From the Editorial Board Based at Columbia University in the City of New York, The Journal of Global Health is a new international student publication released biannually. The mission of this publication is to facilitate dialogue among students at the medical, graduate, and undergraduate level on innovative solutions to interdisciplinary global health issues from a variety of academic, cultural, and geographic perspectives. The health of human populations depends on the collective efforts of professionals from a vast DUUD\ RI ÀHOGV LQFOXGLQJ VFLHQWLVWV SXEOLF SROLF\ PDNers, and medical practitioners. The most pressing global health issues require increasingly interdisciplinary approaches to solving them. Despite substantial recent growth of interest in global health policy and research, there is currently a lack of dialogue among students on global health issues in an organized, academic fashion. In this inaugural issue of The Journal of Global Health, we represent a wide range of perspectives from students throughout the world immersed in a variety of different academic disciplines relating to global health. Instructions for authors interested in submitting for our Fall 2011 issue can be found online at www.ghjournal.org.

Ebola, Emerging: The Limitations of Culturalist Discourses in Epidemiology Jared Jones Yale University, New Haven, CT, USA Abstract In this paper, I offer a critique of the culturalist epidemiology that dominates the discourse of Ebola in both popular and international health spheres. Ebola has been exoticized, associated with â&#x20AC;&#x153;traditionalâ&#x20AC;? practices, local customs, and cultural â&#x20AC;&#x153;beliefsâ&#x20AC;? and insinuated to be the result of African igQRUDQFH DQG EDFNZDUGQHVV ,QGHHG UHLĂ&#x20AC;HG FXOWXUH LV UHFRQĂ&#x20AC;JXUHG LQWR D ´ULVN IDFWRU Âľ $FFRXQWV RI WKH GLVHDVH SDLQW $IULFDQ FXOWXUH DV DQ REVWDFOH to prevention and epidemic control efforts, at times even linking the eruption of the disease to practices such as burial traditions or consumption of bushmeat. But this emphasis is misleading;Íž the assumption of African â&#x20AC;&#x153;otherness,â&#x20AC;? rather than evidence, epidemiological or otherwise, underpins dominant culturalist logics that â&#x20AC;&#x153;beliefsâ&#x20AC;? motivate behaviors which increase the likelihood of Ebolaâ&#x20AC;&#x2122;s emergence and spread. Conspicuously abVHQW IURP ERWK SRSXODU DQG RIĂ&#x20AC;FLDO UKHWRULF KDV EHHQ DWWHQWLRQ WR ODUJHU VWUXFWXUDO GHWHUPLQDQWV RI WKH FRXUVH RI (EROD HSLGHPLFV <HW JOREDO IRUFHV condition the emergence of Ebola far more than culture does. Inequality and inadequate provision of healthcare, entrenched and exacerbated by a legacy of colonialism, superpower geopolitics, and developmental neoliberalism, are responsible for much of Ebolaâ&#x20AC;&#x2122;s spread. Certainly, structural force alone cannot account for the destruction Ebola has wreaked on the lives of victims and their families. Culture does matter. But the focus on culture comes at the expense of attention to sociopolitical and economic structures, obscuring the reality that global forces affect epidemics in Africa. In this paper, I seek to map the discursive contours of Ebolaâ&#x20AC;&#x2122;s emergence, contextualize these trends within a larger debate about the role of anthropology in epidemiology, and question the simplistic link between culture and Ebola through a critical examination of structural-level forces.

During these outbreaks, most of the world took only passing notice of this new disease. Scientists who had dealt with the disease and the Zairois and Sudanese touched by it would not soon forget the epidemic, but media focus was limited and Western concern was low. It was not until the late 1980s that Ebola would â&#x20AC;&#x153;emerge.â&#x20AC;? In 1989, Ebola was detected in a shipment of crab-eating macaque monkeys to a laboratory in Reston, Virginia, and media frenzy ensued (Associated Press, 1989).

For comparison, twice as many children die of malaria each day (WHO, 2003). Yet Ebola looms far larger in the Western imagination. Why? Because the virus represents a threat to Western populations. It could travel from there and infect us here. It could mutate and spark a pandemic. It could be stolen by terrorist groups or weaponized by hostile forces. It has the potential to infect us in a way that malaria, conquered as an epidemic disease in the West and easily treated in resource-endowed hosSLWDOV GRHV QRW $ VLJQLĂ&#x20AC;FDQW ERG\ RI OLWHUDWXUH H[DPLQHV WKH discourse of â&#x20AC;&#x153;emerging and re-emergingâ&#x20AC;? infectious disease. As anthropologist and physician Paul Farmer has argued, such categorizations are often limiting because they imply a change in the biological organism or pathogenicity, when, in fact, diseases emerge and re-emerge because of social forces (Farmer, 1999). Moreover, the terms mask where and for whom the diseases have emerged. Tuberculosis, for instance, never â&#x20AC;&#x153;disappeared,â&#x20AC;? as its label of â&#x20AC;&#x153;re-emergingâ&#x20AC;? might indicate. But those who it continued to infect and kill in shocking numbers were people from the poorest countries. Consider that for OECD countries, tuberculosis has disappeared. It â&#x20AC;&#x153;re-emergedâ&#x20AC;? only when it once again posed a threat to Western populations in the form of Multi-Drug Resistant TB, which was potentially untreatable. 1

Ebola is an example of such a disease, one that emerged into Western consciousness more than it did into the biological landscape. Media coverage of the epidemic in 1976 was virtually non-existent;Íž a search through the New York Times archives indicates that only one article was written about the disease prior to 1989. But after the 1989 macaque monkey incident, media interest exploded. As Paul Farmer writes:
2007). Such arguments convey that Africans are both ignorant and stubborn in their misconceptions while supporting the notion that Ebola outbreaks are caused by a cultural tradition of bushmeat consumption. As I will show later, similar theories of causation link burial practices to outbreaks. More generally, African culture is seen as an obstacle to overcome when implementing outbreak control. Locals are presumed to subscribe to alternative disease models rooted in â&#x20AC;&#x153;traditional healing,â&#x20AC;? believe in sorcery or the supernatural as the cause of the disease, or generally hold â&#x20AC;&#x153;misconceptionsâ&#x20AC;? about its etiology. Laurie Garrettâ&#x20AC;&#x2122;s description of the response to the Kikwit epidemic is telling:
Modern communications, including print and broadcast media, have been crucial in the construction of Ebolaâ&#x20AC;&#x201D;a minor player, statistically speaking, in Zaireâ&#x20AC;&#x2122;s long list of fatal infectionsâ&#x20AC;&#x201D;as an emerging infectious diseaseâ&#x20AC;Ś journalists DQG QRYHOLVWV ZURWH EHVW VHOOLQJ ERRNV DERXW VPDOO EXW KRUULĂ&#x20AC;F SODJXHV ZKLFK LQ WXUQ EHFDPH SURĂ&#x20AC;WDEOH FLQHPD 7KXV V\PEROLFDOO\ DQG SURYHUELDOO\ (EROD VSUHDG OLNH ZLOGĂ&#x20AC;UHÂłDV D danger potentially without limit.

[It was] something called a virus. Something called Ebola. These things gripped the estimated 400,000 people of Kikwit with a terror unlike any they had ever feltâ&#x20AC;Ś The victims died fast, screamed incoherent phrases of apparent devilish origin. They seemed possessedâ&#x20AC;Ś There were ancient ceremonies handed down by the ancestors that could purge evil spiritsâ&#x20AC;&#x201D;they usually lifted the landa-landa [a local name]. But not this time. The magic was too powerful. Surely it must be the work of an exceptionally evil one, who was the potent fount of Satanism (Garrett, 2000).
Toward a Culturalist Epidemiology Ebola did not merely emerge;Íž it emerged from Africa. Since its discovery, the mystery and intrigue surrounding Ebola has been linked to its foreign origins. The virus was exocitized, and the imagery invoked in many minds was that of an ancient evil surfacing from its hidden resting place in the darkness of the $IULFDQ MXQJOH &11 SURGXFHG D VSHFLDO LQ ZLWK HVVHQWLDOO\ this message, describing â&#x20AC;&#x153;a killer on the loose in the rainforHVWÂľ &11 $Q DUWLFOH HQWLWOHG ´7KH 1H[W 3ODJXH DQG the Nextâ&#x20AC;? argues that â&#x20AC;&#x153;[in] the remotest tropics of Africa and South America lurk a coterie of virusesâ&#x20AC;Ś [such as] Ebolaâ&#x20AC;? (Wade, 1994). A New York Times piece describes how â&#x20AC;&#x153;the rare and terrifying Ebola virus has emerged from its hiding place in WKH KHDUW RI WKH $IULFDQ MXQJOHÂľ (GLWRULDO 7KH REVHVsion with Ebolaâ&#x20AC;&#x2122;s â&#x20AC;&#x153;hidden reservoirâ&#x20AC;? in Africa runs through nearly every Western account of the disease in the media. This connection between African culture and Ebola is more than mere rhetorical racialization of the disease. Culture itself is reconstituted as a â&#x20AC;&#x153;risk factorâ&#x20AC;? for infection in light of assumptions about African â&#x20AC;&#x153;Otherness.â&#x20AC;? In both SRSXODU DQG RIĂ&#x20AC;FLDO L H :+2 &'& DFFRXQWV $IULFDQ ´EHliefsâ&#x20AC;?â&#x20AC;&#x201D;often about disease etiology and transmissionâ&#x20AC;&#x201D;are represented as ignorant and backwards, supposedly hindering or counteracting more enlightened epidemic control efforts. Africans are presumed to believe in spirits and witchcraft as the cause of Ebola, and reject biomedicine and the interventions it necessitates. These â&#x20AC;&#x153;beliefsâ&#x20AC;? are sometimes even held to motivate cultural behaviors or â&#x20AC;&#x153;customsâ&#x20AC;? that are responsible for initial outbreak of the disease and facilitate its spread. The Bushmeat Hypothesis, which posits that hunting, slaughtering, and eating infected gorilla or monkey meat is the primary cause of the virusâ&#x20AC;&#x2122;s entrance to a new population, is among the dominant explanations for Ebola outbreaks, and typically these accounts attribute bushmeat consumption to African culture (Fox, 2004). Rural Africans sometimes eat these animals;Íž this fact is UHFRQĂ&#x20AC;JXUHG LQWR QHDU FHUWDLQ SURRI RI D FDXVDO PHFKDQLVP $FDGHPLF VWXGLHV GHSOR\ D WHFKQR VFLHQWLĂ&#x20AC;F GLVFRXUVH WR PDVN this simple cultural logic in advancing the hypothesis. â&#x20AC;&#x153;Despite efforts to change the eating habits of African villagers,â&#x20AC;? con tends one article, â&#x20AC;&#x153;many believe occult forces are behind Ebola. They do not understand that they could limit their exposure by avoiding dead or sick animalsâ&#x20AC;? (Rizkalla, Blanco-Silva, & Gruver, JGH t Volume 1 t Issue 1 t Spring 2011
These statements seem to suggest that Africans hold eccentric and primitive â&#x20AC;&#x153;beliefsâ&#x20AC;? and may not accept the â&#x20AC;&#x153;truthâ&#x20AC;? of modern biomedicine. Byron Goodâ&#x20AC;&#x2122;s Medicine, Rationality, and Experience offers cogent analysis of the epistemology of medicine, which views itself not as a cultural construction, but a logical progression of objective knowledge into techniques designed to correct concrete biophysical abnormalities.

In short, they believe, we know. The answer to the supposed barrier of culture, according to Western physicians and WHO teams, must be community education campaigns and anthropologically minded initiatives.
The Unhappy Marriage of Epidemiology and Anthropology Susan DiGiacomo has argued that anthropology and epidemiology should be natural allies in the study of disease. %XW ZKHQ DQWKURSRORJ\ LV RSHUDWLRQDOL]HG LQ ELRVFLHQWLĂ&#x20AC;F VHWWLQJV ´FXOWXUH LV UHLĂ&#x20AC;HG DV DQ HQVHPEOH RI PHDVXUDEOH ÂśIDFWRUV¡ ZLWK GHWHUPLQLVWLF SRZHU RYHU VSHFLĂ&#x20AC;F DVSHFWV RI LOOQHVVÂľ 'LGiacomo, 1999).

Research Articles on culture at the expense of structure, however, is obfuscating. Take, for instance, the imagery of the village, which is almost universally deployed. Sub-Saharan Africa actually has one of the highest rates of urbanization (which is typically linked to industrialization) in the world. In fact, DROC and Gabon, the two countries with the greatest numbers of Ebola outbreaks, are the two most urbanized countries in Africa at 67% and 84%, respectively (Falola & Afolabi, 2007). Many depictions of Ebola victims invoke the idea of African â&#x20AC;&#x153;traditionalistsâ&#x20AC;? but a large number of those affected by Ebola live in cities, accept the biomedical model of disease, and are amenable to epidemic control efforts. In Ebola, Culture, and Politics: The Anthropology of an Emerging Infectious Disease, Hewlett describes â&#x20AC;&#x153;village life,â&#x20AC;? detailing family organization, social structure, and cataloguing local explanatory models of sorcery or supernatural causation (Hewlett & Bonnie, 2008). Yet the same source also notes that 60% of the cases were in urban, not rural areas (Hewlett & Bonnie, 2008). The Gulu district, where the epidemic occurred, was not some backwards and timeless village;Íž it had three large hospitals, paved roads, nightclubs, restauUDQWV HOHFWULFLW\ DQG QXPHURXV JRYHUQPHQW RIĂ&#x20AC;FHV 7KLV ZDV a modern city, though a poor one.

Nosocomial transmission was shockingly high in Yambuku, as it was in the Nâ&#x20AC;&#x2122;zara outbreak, where Ebola spread rapidly through the staff and patients at the Maridi hospital (Garrett, 1994). Inadequate supplies and unsterile syringes have also been cited in the Uganda HSLGHPLF RI DQG WKH .LNZLW HSLGHPLF LQ +HZOHWW & Bonnie, 2008). One report declares that â&#x20AC;&#x153;in-adequate [sic] and poor quality of protective materials, especially at the beginning of the outbreak, was a big problem and contributed to the transmission of Ebola virus within the health care settingâ&#x20AC;? (Lamunu et al., 2006). The CDC Ebola Factsheet lists nosocomial transmission as one of the most serious causes of the spread of the disease (CDC, 2009). Yet despite the clear role of poor healthcare infrastructure, the focus in the literature has been on education and community mobilization campaigns, consigning inadequately funded hospitals to a status as an unalterable African condition in which epidemics play out. Poverty, inequality, and poor healthcare infrastructure remain outside the realm of conceivable intervention. The shift in emphasis from resources to culture masks the fact that improving the quality of health care and reducing inequalLW\ FRXOG VLJQLĂ&#x20AC;FDQWO\ UHGXFH WKH VSUHDG RI (EROD HSLGHPLFV

(Packard & Epstein, 1991). In short, anthropology has been employed as the handmaiden of epidemiology. Its role has been circumscribed to identifying â&#x20AC;&#x153;beliefsâ&#x20AC;? in order to help design education campaigns and implement â&#x20AC;&#x153;culturally appropriate intervention strategies.â&#x20AC;? Medical researchers ask anthropologists to deal with the â&#x20AC;&#x153;cultural issues.â&#x20AC;? In this light, the discipline has become little more than a specialist in local beliefs and customs. Anthropologists are presumed to have knowledge of culture which they can package into discrete units for international health experts in order to make outbreak control more effective. Many anthropologists seem even to embrace this role. A recent book by anthropologists Barry and Bonnie Hewlett, Ebola, Culture, and Politics: The Anthropology of an Emerging Infectious Disease, effectively serves this purpose. After cataloging local disease models, customs, and beliefs, the bookâ&#x20AC;&#x2122;s conclusion ZDV WKDW ´DQWKURSRORJLVWV FDQ KHOS VROYH VSHFLĂ&#x20AC;F FOLQLFDO ODERratory, epidemiological, and other problems that emerge during an outbreak, such as why people run away from the ambulance, why they refuse to seek treatment at the clinic, andâ&#x20AC;Ś suggest ways to modify clinical and mortuary practices so they are culturally sensitive and appropriateâ&#x20AC;? (Hewlett & Bonnie, 2008). Certainly, there is a need for cultural awareness in any public health campaign or outbreak control. But anthropology discards its position as a contextualizing discipline by circumscribing its role to â&#x20AC;&#x153;explainingâ&#x20AC;? the enigmatic beliefs of locals for use in a behavioralist epistemology. It implicitly reinforces the assumption that behaviors are culturally determined, ignoring social, political, economic, and historical factors that affect health outcomes and disease distribution. Epidemiology has almost always limited itself to an analysis of individual behaviors as â&#x20AC;&#x153;risk factors.â&#x20AC;? Indeed, these individualizing claims of causality may be useful for public health interventions because they allow for rapid targeting of risky behaviors or populations.

The accompanying trade liberalization also diminished, indirectly, healthcare funding, because revenues from tariffs were a sizable portion of government budgets, and as this source dried up, spending had to be further cut.

The persistence of African poverty is a topic too large to examine in the present investigation. But here I will suggest some of the ways in which larger global forces have caused or perpetuated inequality across the continent, and limited the resources available for healthcare provision. Numerous authors point to endemic corruption and the patrimonial tendencies of predatory and autocratic regimes as the cause of poor economic performance and low provision of public goods, including health care.

Political Systems and Health Inequity: Connecting Apartheid Policies to the HIV/AIDS Epidemic in South Africa Victoria Scrubb University of Toronto, Toronto, ON, Canada Abstract South Africaâ&#x20AC;&#x2122;s transition to a post-apartheid government marked a new era of liberation and equality for black South Africans. However, the notions of white supremacy and racial segregation, ideologies of apartheid government, continue to hinder the South African governmentâ&#x20AC;&#x2122;s attempts to restructure its healthcare system. In addition, new economic drives toward privatization act as a new barrier to the achieving of equality in the South African healthcare system. The persistent inequality in the delivery of health care within South Africa is illustrated in the nationâ&#x20AC;&#x2122;s distribution of HIV/AIDS;Íž black South Africans bear the highest burden of disease. This paper argues that the current inability of the South African government to adequately address the HIV/AIDS epidemic is symptomatic of still-existing apartheid ideologies in the healthcare system, faulty public-private relationships, and structural gaps between health policy making and implementation. $SSUR[LPDWHO\ PLOOLRQ SHRSOH LQ 6RXWK $IULFD DUH FXUrently living with HIV, and of these people, 3.2 million are women and 280,000 are children under age 14. 17.8% of 6RXWK $IULFDQ DGXOWV DJHG WR DUH OLYLQJ ZLWK +,9 DQG there are almost 2 million South African children under age 17 who have been orphaned due to HIV/AIDS (UNAIDS, 2011). By overlapping historical analysis of apartheid health policies with current neoliberal discourse, we can witness patterns emerging between HIV/AIDS treatment and incidence disparities and South Africaâ&#x20AC;&#x2122;s political and economic policies. Starting in 1948, black South Africans became the target of exclusionary and exploitive laws that separated South Africans on the basis of race. The government forced black JGH t Volume 1 t Issue 1 t Spring 2011
South Africans to live in designated areas that were separate from areas inhabited by white South Africans. These areas, known as Bantustans, comprised of merely 13% of South Africa in size but were home to over 80% of the population (Price, 1986). In each Bantustan, a large number of which were situated in rural South $IULFD KHDOWK FDUH ZDV SULPDULO\ SURYLGHG E\ QRQ SURĂ&#x20AC;W PLVsionary hospitals and overseen by local elites. By giving control of the healthcare system to individual Bantustans, the national government of South Africa essentially removed its responsibility to monitor and account for the quality of health services in those areas. Due to little government regulation and oversight of privatized health care during apartheid, health services in Bantustans frequently ignored quality-of-care guidelines and became 6

places of abuse and maltreatment (Kon & Lackman, 2008). In many cases, black South Africans who resided in urban areas were largely employed as caregivers, cooks and laborers, and other jobs that put them in contact with the white South African population. Basic health services were provided by the South African government to urban blacks to prevent them from spreading disease to the white South African population that inhabited urban areas (Price 1986). Because very few white South Africans resided in Bantustans, there was little interest amongst South African health policymakers to ensure that basic health care would be provided in rural hospitals. The odds of continuous contact between black populations of Bantustans and white South African populations were low. Almost two decades after the end of apartheid, vast disparities exist in South African HIV/AIDS prevalence and health care. For example, HIV prevalence in the more urbanL]HG :HVWHUQ &DSH SURYLQFH LV DW LQ FRPSDULVRQ WR KwaZulu-Natal, which has an HIV prevalence of 39.1% (UNAIDS, 2011). In addition, infant mortality was 20% among EODFNV EXW RQO\ DPRQJ ZKLWHV OLIH H[SHFWDQF\ ZDV years for blacks and 70 years for whites. There was one physician for every 330 whites but only one for every 91,000 blacks (Kon & Lackman, 2008). In addition to diffusing its responsibility to provide national health services, the apartheid-era government limited the budgets for rural health systems. In 1978, for example, merely 0.23% of the South African GNP was allocated to health systems in Bantustans whereas as 2.3% was given to urban health centers (Price, 1986). Even while Bantustan health care was already subject to limited funding and inferior services, the organization and execution of health care within rural areas furthered ethnic divisions. Delivery was organized through ethnically segregated health services that simultaneously reinforced apartheid ideologies of racial division. Hospitals in Bantustans were â&#x20AC;&#x153;staffed by people from the ethnic group of the relevant authority and who were supposed to treat only patients of the same ethnic groupâ&#x20AC;? (Price, 1986). As a result, workers and patients were forced to think not only in terms of black and white but also in terms of their sub-ethnic identity, in a setting of communities subdivided based on kinship lineages and marriage. This, in turn, contributed to ethnic consciousness centered on the belief that people needed to be separated into ethnically hoPRJHQRXV QDWLRQ VWDWHV LQ RUGHU WR PLQLPL]H FRQĂ LFW 6XFK relationships illustrate the broader connection between politics, socialization, and health outcomes. Moreover, even after the end of apartheid, the goals of securing white supremacy and promoting racial segregation set by the apartheid government continued to inhibit South Africaâ&#x20AC;&#x2122;s potential to implement effective health policies that aimed to reduce social disparities in terms of access, quality of service, and treatment.

By the early 1980â&#x20AC;&#x2122;s, 40% of South African healthcare professionals worked in the private sector, but, by the 1990s, that percentage had climbed to 66% (Kon & Lackman, 2008). Overcoming the unequal distribution of human resources between the public and the private healthcare system is a major existing problem in South Africa. Health care professionals in rural clinics tend to have more poorly developed skills and less management experience, and the entire South African public KHDOWK V\VWHP LV SODJXHG E\ XQGHUVWDIĂ&#x20AC;QJ DQG RYHUFURZGLQJ of patients (Coovadia et al., 2009). Compounded by the presence of hundreds of community health workers sponsored by non-governmental organizations, there is little standardization in terms of the training, oversight, and supervision of South African healthcare workers, which ,in turn, has compromised the delivery of key programs in child health, maternal health, tuberculosis, and HIV/AIDS (Coovadia et al., 2009). In 1990, when privatization of healthcare was still in its elementary stages, the HIV/AIDS prevalence was 0.7% in South Africa;Íž however, by 1994, the HIV/AIDS prevalence was 8%.

As a result, the rural health sector was consolidated from 400 independently-run local systems into nine provincial healthcare systems (Kon & Lackman, 2008). Although responsibility for implementing public programs remained at the provincial level, the national government sought to ensure that the collection and distribution of revenue was equitable, and it set new standards for service provision (Schneider & Stein, 2001). In collaboration with the National AIDS Committee of South Africa, the new government also introduced a National AIDS Plan that would place the prevention and treatment of HIV/AIDS at the forefront of the nationâ&#x20AC;&#x2122;s health policy. Under the leadership of the post-apartheid government, the National AIDS Plan initiated a cooperative effort to alleviate the burden of HIV/AIDS on the South African population through the promotion of primary health care, preventative interventions, and educational initiatives regarding condoms, safe sex and treatment optionsâ&#x20AC;&#x201D;all of which focused heavily on government action via the local level (Wouters, Rensburg, & Meulemans, 2010). While the push to offer such programs to South Africans at the local level was a progressive idea that recognized local diversity and attempted to strengthen the Bantustan health system, the National AIDS Plan grossly overlooked the inability of existing functional organizations and infrastructures to comply with the new standards. South African healthcare became increasingly fragmented and decentralized by this particular policy. At the time, local leaders were ill-equipped to manage the organizing, problem solving, and coordinating needs of the National AIDS Plan (Schneider & Stein, 2001). Consequently, the National 7

AIDS Plan was unable to counter the transmission of HIV/ AIDS or provide necessary treatment to HIV-positive patients. The failure of the post-apartheid government to address HIV/AIDS highlights the importance of making policies compatible with feasible implementation strategies. The National AIDS Plan was a strategy that was hampered by political instability, concurrent societal reconstruction, and a weak preexisting healthcare infrastructure. A likely result of the demands made by the black South African population for treatment, government funding for the treatment of HIV/AIDS rose IURP LQ WR LQ :RXWHUV HW DO Since the seeming failure of the second governmentâ&#x20AC;&#x2122;s attempt to mount a national strategy against HIV/AIDS and decrease HIV/AIDS mortality and prevalence, the international community has vehemently criticized the inability of the South African government to adequately address the needs of civil society, to involve its citizens in the process of healthcare policy making, and to address the lack of overall governmental accountability in the provision and division of healthcare funds. As a result, the latest National Strategic Plan on AIDS 2007-2011 has incorporated national, non-governmental, and civil bodies, and it has been hailed as â&#x20AC;&#x153;South Africaâ&#x20AC;&#x2122;s most dynamic and comprehensive document yet on AIDS issuesâ&#x20AC;? (Wouters et al., 2010). The National Strategic Plan prioritized prevention of HIV (mother to child and among youth), HIV treatment, and HIV research, monitoring and surveillance, with an emphasis on increasing access to HIV/AIDS treatment (Wouters et al., 2010). However, while the National Strategic Plan 2007-2011 has addressed numerous pressing issues from previous policy failures, it nonetheless fell short of its goals. The main objective of the 2007-2011 Plan was to extend treatment to the majority of people with HIV/AIDS;Íž however, because of poor budgeting and limited human resources, the potential success of this plan was unmet, leading instead to a decrease in treatment options for people with HIV/AIDS. Additionally, the private sector continues to harbor the majority of healthcare professionals even though the public sector supports 82% of South Africans (Wouters et al., 2010). Despite the populationâ&#x20AC;&#x2122;s dependence on the public healthcare system, only one out of every three South African doctors works in the public sector, which has become heavily supported by professional nurses.

The South African government inherited a political system characterized by unequal distribution of wealth and resources in addition to the challenge of rising HIV/AIDS prevalence in its black population. Whereas the private sector was largely supported by the international community and continues to provide high quality care, it is also extremely limited in scope. Despite increased pressure from international communities to reduce public healthcare expenditure in favor of privatization, the government should be more conscious of the needs of the black South African population when making healthcare policies. Similar to the HIV and AIDS and STI National Strategic Plan 2007-2011, long term solutions that address funding and the redistribution of human resources will give South Africa the potential to overcome the legacy of apartheid and effectively reduce the impact of HIV/AIDS on the South African population.

ART eligible subjects who had either accepted or refused ART were interviewed and examined to: a) assess their use of traditional medicine, and b) identify perceived (patient self report and physician examination) and objective (anthropometric measurement-based) features of LD. Concern about lipodystrophy was reported to affect acceptance of ART by 19 patients (36%) who accepted ART (p < .01) and affect adherence to ART amongst 3 patients (6%) who accepted ART.

Again, limited data is available on the effect of traditional medicine use on ART acceptance. In this report, we present data on patient self-assessment and physician assessment of lipodystrophy, as well as anthropometric measurements from an HIV-infected trial population in Dar es Salaam, Tanzania. Also, we summarize attitudes toward ART use as they relate to concerns about lipodystrophy and use of traditional medicine.
Antiretroviral Therapy (ART) consists of drug combinations that are used in the treatment of HIV infection. It is usually a combination of at least three drugs, including a Nucleoside or Nucleotide Reverse Transcriptase Inhibitor (NRRTI), a Non-Nucleoside Reverse Transcriptase Inhibitor (NNRTI), and a Protease Inhibitor (PI). Since 2003, various international initiatives have supported efforts to increase ART access for people living with HIV in low-income countries. At the end of 2008, more than 4 million people were receiving ART, two-thirds of whom were from Sub-Saharan Africa. The use of antiretroviral therapy has been found to decrease the severity of HIV/AIDS-related illnesses, de crease mortality, and improve survival among HIV/AIDS patients. As access to ART continues to increase in resourcelimited settings, it is important to understand factors that LQĂ XHQFH +,9 WUHDWPHQW LQLWLDWLRQ DQG GUXJ DGKHUHQFH It has been found that among patients who accept ART in resource-limited settings, rates of adherence are comparable to those reported in industrialized countries (Gill, Hamer, 6LPRQ 7KHD 6DELQ /DXUHQW HW DO 6SDFHN HW al., 2006). However, data on correlates of HIV-infected patientsâ&#x20AC;&#x2122; initial acceptance of ART in resource-limited settings are not widely available (Fisher et al., 2006;Íž Hardon et al., 2007;Íž Karcher, Omondi, Odera, Kunz & Harms, 2007). Based on our experiences with ART adherence and acceptance among HIV-infected patients enrolled in a TB vaccine trial in Tanzania, almost 30% of ART-eligible patients who we worked with were reluctant to accept ART.

Research Articles We hypothesized that lipodystrophy is common among patients on ART in Tanzania. In addition, we hypothesized that fear of lipodystrophy may contribute to decreased likelihood of ART initiation. Among patients who initiated ART, fear of lipodystrophy may also contribute to reduced likelihood of adherence to ART medication. Similarly, traditional medicine is common among HIVinfected patients in Tanzania, and it may also contribute to decreased likelihood of ART initiation. Among patients who initiated ART, use of traditional medicine may contribute to decreased likelihood of ART adherence.

Initiated in 2001, the DarDar study is a Dartmouth Medical School/ Muhimbili University of Health and Allied Sciences (MUHAS) collaborative phase III trial to evaluate a BCG prime-boost vaccine strategy for the prevention of HIV-associated tuberculosis (TB) (Vuola et al., 2003). We gratefully acknowledge the support of and contributions made by the participants and the staff of the DarDar Study. In the DarDar study, participants were ambulatory HIVinfected subjects over the age of 18 years with a CD4 count > 200/mm3, two positive ELISA tests for HIV, a BCG scar, and no evidence of active TB. They were followed every three months for routine clinical care with periodic laboratory analyses. At each visit, subjects who met 2003 World Health Organization HIV Care and Treatment criteria for ART treatment initiation were counseled and referred to ART clinics.

Selected subjects were informed of the study and invited to participate via telephone contact or home visit to account for phone unavailability.

Anthropometric measurements Height, weight, mid-upper arm circumference (MUAC), hip-circumference, and waist-circumference were measured according to the Lohman anthropometric standardization manual (Lohman, Roche, & Martorell, 1988). Height was measured with a stadiometer and weight measured (in kg) by a beam balance in kg (without shoes). Using a tape measure (in cm), waist circumference was measured at the narrowest area around the waist just above the navel, hip circumference was measured at the largest extension of the buttocks, and MUAC was measured halfway between the acromium and the olecranon of the non-dominant arm.

The members of DWC each have varying degrees of fourth ventricular cystic dilation, vermian dysgenesis, and posterior fossa enlargement, as described in the sections that follow. In increasing severity, the DWC includes mega cisterna magna (MCM), Blakeâ&#x20AC;&#x2122;s pouch cyst (BPC), Dandy-Walker variant (DWV), and Dandy-Walker malformation (DWM).

Furthermore, while the medical care these patients receive while hospitalized is of utmost importance, the social environment surrounding the patient and its implications for a successful recovery cannot be overstated. Hydrocephalus, whether associated with DWC or another cause, carries a powerful stigma in many cultures;Íž it is a stigma that poses great barriers to patient recovery and societal assimilation.

Communities will often reject the mother and child for fear that either one carries a negative contagion that could disrupt society. Unfortunately, some mothers will even kill their children in an effort to escape the burden or rid her community of a presumed evil being. It is for these reasons that the hospital maintains an active and well-supported social outreach team charged with educating patient caregivers about their childâ&#x20AC;&#x2122;s disease, and offering VSLULWXDO VRFLDO YRFDWLRQDO DQG RFFDVLRQDOO\ Ă&#x20AC;QDQFLDO VXSSRUW It became apparent early in the establishment of CCHU that surgical outcomes correspond with the degree of social support surrounding a patient and his or her caregiver(s).

During this evaluation, caretakers often paint a picture of the hardships suffered during the life of their child. A plan is then made for each patient, and social workers, religious staff, and medical personnel work in concert to address these challenges and develop solutions.

This knowledge is meant both to eliminate the caretakerâ&#x20AC;&#x2122;s fear that their child is a form of punishment and to empower him or her with knowledge to educate community members at home. Religious leaders employed by the hospital are available to counsel caregivers and their children throughout their hospital stay. Families are free to interact as much or as little as they choose with the religious staff. Spiritual counseling is available to guests on an individual basis, and prayer and song sessions are regularly held for community worship. CCHU strives to accommodate patients from every geographic region and tribe of Uganda and beyond. With over 80 different tribes and scores of distinct languages and dialects, CCHU employs staff that speak dozens of languages to ensure that patient caretakers can tell their childâ&#x20AC;&#x2122;s story in their native tongue. The hospital leadership believes that of all the obstacles faced by these patients, a language barrier is one that can be eliminated from the outset.

Language of the Heart: A Studentâ&#x20AC;&#x2122;s Perspective on Congenital Heart Defects and Volunteering Alina Yang Princeton University, Princeton, NJ, USA Lan Xiao Hua is a 13 year old girl from Gansu, China. She had Ventricular Septal Defect, a hole in her heartâ&#x20AC;&#x2122;s right ventricle. Doctors said she would be able to live to approximately 20 years of age. Xiao Huaâ&#x20AC;&#x2122;s family knew about her congenital heart disease (CHD) since she was 7 years old, but with the humble living they made coaxing wheat from the dry, parched land of Gansu Province, the necessary surgery expenses would have required 10 yearsâ&#x20AC;&#x2122; worth of their income. Xiao Huaâ&#x20AC;&#x2122;s condition is not untreatable. Rather, CHD requires what is considered one of the simpler cardiac surgeries. Had Xiao Hua been operated on earlier, the chances of a successful surgery would have been almost 99%. After the surgery, she would have been completely normal, with JGH t Volume 1 t Issue 1 t Spring 2011
few lingering symptoms. Instead, without the necessary surgery for CHD, Xiao Hua was easily exhausted by the simplest of everyday activities, such as walking. Her lips were tinted blue whenever she did any work. Even breathing was painful for her. Xiao Hua was more susceptible to transmittable diseases and caught colds frequently, a symptom of poor blood circulation. She was also shorter than other 13-year-old girls because her faulty heart contributed to stunted growth and development. Xiao Hua desperately needed the heart surgery, but she didnâ&#x20AC;&#x2122;t have the resources needed to obtain treatment. Lan Xiao Huaâ&#x20AC;&#x2122;s plight is not unusual. Congenital heart defects (CHD) are a leading cause of child mortality both worldwide and in the U.S. According to the American 16

Because water can sell at roughly 80 RMB per barrel, families struggle to provide proper nourishment for pregnant women and their growing fetuses. While it cannot be concluded that lack of precipitation is directly linked to CHD, it does, however, affect the diets and nutrition of Gansu families.

Defects range in severity from simple problems, such as â&#x20AC;&#x153;holesâ&#x20AC;? between chambers of the heart, to very severe malformations, such as complete absence of one or more chambers or valves. In severe defects, CHD can lead to heart failure, a condition in which the heart is unable to pump blood throughout the body. Other common results include lifethreatening brain infections and the hemorrhaging of the heart.

Nearly two times more American children die from congenital heart disease annually than those who die from all other forms of childhood cancers combined (Childrenâ&#x20AC;&#x2122;s Heart Foundation, 2009).

Today, the outlook for a child with a congenital heart defect is better than ever.
Causes and Treatment of CHD Researchers do not yet fully understand why CHD develop. Many scientists and philanthropic foundations highlight the role of heredity in some heart defects (American Heart Association, 2011;Íž Bruneau 2008;Íž Gelb & Weismann 2007;Íž Pierpont et al. 2007). For example, an individual who has a congenital heart defect may be especially likely to have a child with a similar condition. The American Heart Association advises that pregnant women should avoid alcohol, drugs, and environmental toxins to decrease the chance that their newborns would develop congenital malformations. (American Heart Association, 2011). Unfortunately, for the majority of CHD cases, the precise cause of CHD remains unknown. Treatment ranges from procedures that use catheters to repair the defect to open-heart surgery, and, in the severest cases, heart transplants are an option.
What Is Overlooked? While possible causal agents of CHD include drugs, chemicals, and infections during a fetusâ&#x20AC;&#x2122; development in the womb, or genetic and chromosomal defects apparent shortly after conception, mainstream resources for medical knowledge overlook another noteworthy possibility: socio-economic correlates. It may not be a coincidence that Gansu, China, which has a CHD incidence rate that is six times Chinaâ&#x20AC;&#x2122;s average, also has a poverty rate three times Chinaâ&#x20AC;&#x2122;s average poverty rate. Millions of rural residents in Gansu work in subsistence farming and animal husbandry, earning an average annual per capita income thatâ&#x20AC;&#x2122;s only 63% of Chinaâ&#x20AC;&#x2122;s average income in 2000 (Adams et al, 2008). Extreme drought is common in Dingxi, Gansu, 17
The future Today, the outlook for a child with a congenital heart defect is better than ever. Advances in testing and treatment give most children born with heart defects the chance to grow into adulthood and the ability to live active, productive lives. However, it is also true that Lan Xiao Huaâ&#x20AC;&#x2122;s condition was most likely not due to genetic disorder, or irresponsible consumption of drugs and alcohol on the part of her mother.

Studies published on all the congenital anomalies (CAs) have either indicated no clear socioeconomic or psychosocial correlates of CHD or a higher prevalence of CAs among children born to lower social class mothers. (Knox et al, 1991;Íž Olsen et al, 2003;Íž Stone et al, 1989). More research is urgently needed to examine psychosocial and socioeconomic correlates of CHD incidence.

The Case for Strong Immunization Programs The advent of childhood vaccinations revolutionized the Ă&#x20AC;HOG RI SXEOLF KHDOWK DQG FRQWLQXHV WR EH RQH RI WKH PRVW FRVW effective public health interventions. Vaccinations led to the eradication of smallpox in 1979, and scientists are currently on the cusp of using vaccinations to eradicate poliomyelitis (Modlin, 2010). Recent estimates provide an illustration of the effective nature of vaccines: immunizations averted up to 61% of measles deaths, 69% of tetanus deaths, 78% of pertussis deaths, 94% of diphtheria deaths, and 98% of polio deaths that would have occurred in the absence of vaccinations (Jamison, Breman, & Measham, 2006). These estimates are derived from mathematical models that focus on susceptible proportions of the population, infectivity rates of disease, and case fatality rates. In 2003, it was estimated that immunizations prevented two million childhood deaths from measles, neonatal tetanus, and pertussis (Tangermann, Nohynek, Eggers, 2007). However, there is a wide disparity in access to vaccines between industrialized and developing countries, as evidenced by the non-uniform global GHFOLQH RI PRUWDOLW\ UDWHV LQ FKLOGUHQ XQGHU Ă&#x20AC;YH ,Q .HQ\D WKH LQFUHDVH LQ FKLOG PRUWDOLW\ ZDV SHU \HDU DPRQJ WKRVH UHsiding in rural areas and among those who lack a formal education (Houweling, Kunst, Moser, & Mackenbach, 2006).

With this crop of vaccinators, we were afraid that the quality of our immunization program could be compromised. It was important to set up a one day workshop on fundamentals of immunization to educate the selected vaccinators. The workshop covered the tallying process, administration of antigens, community mobilization, contraindications, and surveillance of adverse reactions.

These are the main reasons why lack of routine immunization activities at the Primary Healthcare Center (PHCC) are in line with low immunization coverage rates in South Sudan. The national cold chain storage is at Juba, the capital of South Sudan, but vaccines do not trickle down to more rural and inaccessible areas of the country. It would take a long time for the Southern Sudan government to provide permanent electricity to Kajo Keji County. Electricity is a requirement for cold chain maintenance. In the meantime, routine immunization strengthening can be achieved by procuring solar freezers and kerosene fridges at every Primary Healthcare Unit (PHCU).

The steady rise of HIV infections has been a source of grave concern for health workers not only due to its immediate economic and health costs but also the danger it presents in the future.

Factors Detrimental to HIV/AIDS Control
The momentum gathered in the past few years in addressing the spread of HIV in Pakistan may soon be lost. Despite having constructed a thorough plan to prevent the spread of HIV/AIDS, Pakistan currently faces severe shortages that may hinder the initiatives in NSF-II from proceeding.

Despite considerable interest in global health education from students and its reportHG EHQHĂ&#x20AC;WV KRZHYHU PRVW VFKRROV KDYH QRW LQWHJUDWHG IRUPDO global health programs into their curricula (Izadnegahdar et al., 2008;Íž Panosian & Coates, 2006). Only recently have formal ethical guidelines for global health experiences been introduced (Crump, Sugarman, & Working Group on Ethics Guidelines for Global Health Training, 2010;Íž Provenzano et al., 2010). The lack of an institutionalized framework for global health education has had important ethical and educational implications for medical students who pursue electives in resource-poor settings. International research programs are governed by well-developed clinical guidelines, but global clinical electives carry with them many ethical challenges that have received relatively little attention (Shah & Wu, 2008). While international research programs contribute to the larger academic discourse and are subject to institutional review board approval and other ethical standards, clinical programs that involve students also impact the local community and thus require similar attention. In particular, the perspectives and needs of institutions that host and support foreign students at the international clinical sites in low-resource settings (â&#x20AC;&#x153;host institutionsâ&#x20AC;?) have been neglected. Electives have been described as a â&#x20AC;&#x153;one-way opportunityâ&#x20AC;? that favor students who visit from wealthier institutions (Mutchnick, Moyer, & Stern, 2003). Paradoxically, the disproSRUWLRQDWH IRFXV RQ WKH EHQHĂ&#x20AC;WV IRU YLVLWLQJ VWXGHQWV UDWKHU WKDQ for the host institution reinforces the same disparities in wealth and opportunity that global health programs seek to address. The case studies presented here, based on the experiences of the student authors, show the need for a more cohesive, informed approach to global health electives. Through building formal, long-term, global North-South partnerships, medical schools and host institutions may prevent many of the ethical dilemmas that arise as a result of global clinical experiences (Horton, JGH t Volume 1 t Issue 1 t Spring 2011

(Crump & Sugarman, 2008). To further complicate such challenges, host institutions with fewer resources may be hesitant to address such concerns with wealthier, â&#x20AC;&#x153;sending institutionsâ&#x20AC;? to avoid jeopardizing relationships. Reasonable expectations for both institutions should be made explicit at the outset of collaboration. For instance, comprehensive pre-departure training for students is one way to decrease the demands on hosting institutions. Mentors in developing countries should be able to expect visiting students to be well-prepared for the experience with knowledge of the regional culture, local disease epidemiology, and local language when possible. Electives implemented within a structured partnership can alleviate the demands on the host country by providing an infrastructure for student preparation at home.

The informed consent process, however, takes on further complexity when one participates in the care of patients of an entirely different culture, and provides an example of why cultural competency training is necessary for successful global rotations. While the concept of â&#x20AC;&#x153;informed consentâ&#x20AC;? is largely heralded by international human rights groups, its value and role may have a different meaning in different cultures (Barry, 1988).

With this insight, Elisa could have sat down with her mentor and discussed her thoughts and questions about informed consent.

Ideally, institutional partnerships should provide equitable educational opportunities for medical students from both the global North and global South.

Conclusion: Recommendations for Ethical and Equitable Global Electives
Several recommendations are offered here for global collaboration between medical schools and host institutions (See Table 1), with the primary aim of improving the quality of patient care in low-resource settings. Several different collaborations model this goal, exemplifying both the feasibility and importance of these relationships and pre-departure trainings (AFMC Global Health Resource Group, 2008;Íž Barry, 2011;Íž Chase & Evert, (LQWHU] .HOOH\ 0DPOLQ 9DQ 5HNHQ (OHFWLYHV IRU students from both the global North and global South represent one component of such collaboration.

Fighting Stigma: Lymphatic Filariasis Zaina Naeem University of Pennsylvania, Philadelphia, PA, USA Introduction Mosquitoes are everywhere, and millions of people fall victim to mosquito bites daily. While mosquito bites are generally harmless, for those who live in underdeveloped countries, these bites carry diseases that result in severe socioeconomic and physical subordination (Wynd et al., 2007). People who contract Lymphatic Filariasis (LF), an infectious disease transmitted by mosquitoes, may experience grotesque enlargements of their affected body parts, which include the arms, the legs, and the genital areas. When such swelling occurs, the patient is said to have progressed to a stage of LF known as elephantiasis, a term designed for the elephant-like texture of the resulting skin (Evans, Gelband & Vlassot, 1993). ,Q WKH :RUOG +HDOWK 2UJDQL]DWLRQ FODVVLĂ&#x20AC;HG /) DV D SRWHQWLDOO\ UHFWLĂ&#x20AC;DEOH GLVHDVH 6LQFH WKHQ WKH :RUOG +HDOWK $Vsembly has called upon its member states to initiate drug pro-

Approximately 120 million people are already infected with LF, and 40 million have advanced to elephantiasis (Evans et al., 1993;Íž Sudomo, Chayabejara, Duong, Hernandez, Wu & Bergquist, 2010;Íž Wynd et al., 2007). In these countries, medical access and hygiene measures do not adequately accommodate overpopulation (Wynd et al., 2007). Reforming the healthcare systems of these countries, contrary to popular belief, is not enough. Battling LF is an issue that requires a profound radicalization of human thought. However, before we can begin to examine what is implied by this â&#x20AC;&#x153;revolution of thought,â&#x20AC;? it is important to understand how LF is contracted and spread.

Perspectives A Peek into the Biology of LF
LF is caused by a nematode, a long thin parasitic worm, ranging from 7-10 cm in length, that resides in the lymph channels of the infected person. The adult form, known DV PDFURĂ&#x20AC;ODULD PDWHV DQG UHOHDVHV PLOOLRQV RI ODUYD FDOOHG PLFURĂ&#x20AC;ODULDH PI LQWR WKH EORRGVWUHDP $KRUOX 'XQ\R Koram, Nkrumah, Aagaard-Hansen & Simonsen, 1999). Now mosquitoes become relevant. Mosquitoes serve as transmitting agents for LF. Several mosquito genera can transmit LF, but the most common is Wuchereria bancrofti. Other genera include Culex quinquefasciatus, which breeds in dormant water in urban villages, and Brugia malayi, which LV VRPHZKDW FRQĂ&#x20AC;QHG EHFDXVH LW UHTXLUHV IUHVKZDWHU SODQWV found in rural areas for growth of larvae (Evans et al., 1993). A female mosquito takes a blood meal when it bites a person who has mf circulating in his/her bloodstream. As it sucks blood, the female mosquito also ingests the mf. For 12 days, the mf progressively mature in the mosquito and enter the â&#x20AC;&#x153;infective stage.â&#x20AC;? At this point, when the mosquito takes another blood meal, the mosquito can now pass mf into another personâ&#x20AC;&#x2122;s bloodstream, thereby infecting the person (Evans et al., 1993). The mf continue to grow in the hostâ&#x20AC;&#x2122;s bloodstream, and eventually migrate into the lymphatic system, ZKHUH WKH\ EORFN WKH Ă RZ RI O\PSKDWLF Ă XLG 7KH EORFNDJH FDXVHV WKH Ă XLG WR GUDLQ LQWR WKH H[WUHPLWLHV RI WKH ERG\ XVXally the legs and feet, where phenotypic changes in the skin become apparent. These changes depend directly on the activity of the worms, and the consequential blockage in the lymph nodes (Burril, Loutan, Kumaraswami & Vijayasekaran, 1996).
The Physical & Socioeconomic Impacts
â&#x20AC;&#x153;As the severity of the disease becomes more apparent, social and economic stigma follow suit.â&#x20AC;? Most patients with LF tend to experience skin fold thickening and pigmentary changes to their skin. In these instances, the infected skin hardens and develops small bumps, such that even pressing cannot dent the skin. Furthermore, due to the dryness of the skin, soaking the patientsâ&#x20AC;&#x2122; skin in water does not relieve the painful cracks that soon develop (Burril et al., 1996;Íž Evans et al., 1993). Along with skin changes in the early stages of LF, infected persons also have to battle other infections. The lymphatic system is vital to the elimination of pathogens, and a blockage of the system causes an onset of secondary diseases that make it even more difĂ&#x20AC;FXOW IRU SDWLHQWV WR OLYH D QRUPDO OLIHVW\OH %XUULO HW DO Swelling of body parts is a consequence of LF. 7KRVH ZKR KDYH VZROOHQ WRHV Ă&#x20AC;QG LW QHDUO\ LPSRVVLEOH WR wear shoes, which are vital for protection against the outside environment.

In this way, infected persons become breeding grounds for further diseases (Burril et al., 1996). The trauma of LF patients does not end here. Those who continue to experience progressive swelling are declared to have elephantiasis and are in for a life of painful disability. As the severity of the disease becomes more apparent, social and economic stigma follow suit. Most females in India, East Africa, and Haiti, for example, are expected to nurture children (Wynd et al., 2007). However, young, unmarried women with LF are unable to abide by the standards set by society, due to limited marriage prospects (Wynd et al., 2009). In Thailand and West Africa, there is a common perception that children born to LF-infected women will also inherit the genes for the disease (Wynd et al., 2009). There are also VLJQLĂ&#x20AC;FDQW HFRQRPLF LPSOLFDWLRQV WKDW HQIRUFH WKH LPDJH RI these infected LF womenâ&#x20AC;&#x2122;s being poor marriage prospects. In fact, a study on infected Haitian women by Coreil and colleagues found that many women were unable to â&#x20AC;&#x153;harvest the garden produce because [one] has to stand to do it.â&#x20AC;? 7KHVH ZRPHQ WKXV VWUXJJOH WR Ă&#x20AC;QG D SDUWQHU DQG DQ LGHQWLW\ LQ +DLWL DQG FRDVWDO *KDQD ZKHUH Ă&#x20AC;QDQFLDO FRQWULEXWLRQV WR the family are essential aspects of social culture (Coreil et al., 1998). It is this very fear of an economic burden and of increased attention to their infected state that render many women reluctant to seek treatment, even if they have desires for such treatment. Coreil and colleagues reported one family memberâ&#x20AC;&#x2122;s sentiment: â&#x20AC;&#x153;Youâ&#x20AC;&#x2122;ve lived with it this long, why do you need this treatment so far away?â&#x20AC;? Another woman expressed her despair: â&#x20AC;&#x153;I ask for death because it makes me very sick. Iâ&#x20AC;&#x2122;ve been suffering with this for 33 years.â&#x20AC;? Men with LF share similar sentiments, especially in regards to marriage and employment problems (Wynd et al., 0DOH VH[XDO GLVDELOLW\ KDV QRW EHHQ VLJQLĂ&#x20AC;FDQWO\ VWXGied, but even so, it is believed that young men with hydrocele, another form of LF, struggle to â&#x20AC;&#x153;establish their sexual identity and their capacity to be reliable economic providersâ&#x20AC;? (Coreil et al., 1998). In South America, for example, researchers discovered that many marriages lacked sexual activity due to the painful intercourse resulting from LF (Wynd et al., 2009). In Tanzania and Haiti, for example, men in the advanced stages of LF are considered socially â&#x20AC;&#x153;unacceptableâ&#x20AC;? to the rest of society due to their inability to produce a child (Evans et al., 1993). Infected men and women are thus unable to and sometimes prohibited from selling garden produce in the market by the rest of society, and therefore cannot contribute to the household economy (Coreil et al., 1998). This exclusion leaves these individuals seemingly helpless, with few options to alleviate their social and economic distress.

ment programs in endemic areas, and give the 120 million people infected with LF a chance to be treated for their illness. In addition, attempts to raise awareness on LF give inhabitants of endemic areas a chance to better understand how LF can be prevented and treated. And once the misconceptions are corrected, as seen in Tanzania and the Philippines, the citizens of these countries may be empowered to take better care of their hygiene and well being (Evans et al., 1993).
â&#x20AC;&#x153;Those who have LF are often excluded from society due to a dichotomy that exists between â&#x20AC;&#x153;usâ&#x20AC;? (the uninfected) and â&#x20AC;&#x153;themâ&#x20AC;? (the infected).â&#x20AC;? It is essential that we embrace an open mind when we encounter disability, and relay tolerance to others. Those who have LF are often excluded from society due to a dichotomy that exists between â&#x20AC;&#x153;usâ&#x20AC;? (the uninfected) and â&#x20AC;&#x153;themâ&#x20AC;? (the infected). These labels cause those who suffer from LF to fall to the bottom rung of the social ladder, contributing to a sense of subjugation and subordination. When most people encounter a description of LF or meet an individual with LF, they may tend to cringe back in horror and feel a sense of relief for not being infected. Coreil and colleagues describe how LF patients â&#x20AC;&#x153;received glancesâ&#x20AC;? and were subjected to rude remarks about their infected arms. The disgust and alienation that these patients received contributes to a striking decrease in their self-esteem. In fact, one women reported that she â&#x20AC;&#x153;hopes to dieâ&#x20AC;? because she has been living with the disease for such a long period of time (Coreil et al., 1998). It is this general attitude that needs to be upturned in order to truly combat LF and its implications. We have to realize that those who suffer from disabling and deforming diseases are humans too. They deserve to be integrated into the everyday activities of society. There LV QR UHDVRQ ZK\ SHRSOH H[SHULHQFLQJ LQĂ DPPDWLRQ GXH to LF should be shunned from the school and work community, or be considered useless and a burden on society. We need to talk and listen to organizations and individuals connected with LF, and decrease the schism that exists between these individuals and the rest of society. We unconsciously endorse â&#x20AC;&#x153;inclusive exclusion,â&#x20AC;? a phrase that reveals the â&#x20AC;&#x153;dual natureâ&#x20AC;? of combating LF. On one hand, we attempt to help LF patients by improving their physical health through medical preventions, but on the other hand, our mindset still remains somewhat dehumanizing as we see these people who live so differently from us.

The lack of consensus as to what â&#x20AC;&#x153;global healthâ&#x20AC;? means poses a number of important problems, both for the present and for future generations.

Consider a lack of uniformity found in global health training programs and how, for graduates of such programs, the career pathways are less clear and consistent than those in related disciplines such as public health. In the United Kingdom, for example, doctors may choose to specialize in public health in the same way they might train in cardiothoracic surgery or psychiatry. There currently exists no such equivalent for global health. A lack of consensus on aims means that it is hard to make appropriate comparisons between the increasing numbers of benchmarks that are used. How do we compare and prioritize between efforts to increase the resilience of vulnerable populations to climate change with efforts to reduce irrational antibiotic use so as to prevent resistance from developing?

Spotlight on Fukushima: The Aftermath Interview with Norman J. Kleiman, Ph.D Mailman School of Public Health, Columbia University Credit: JGH
Norman J. Kleiman, Ph.D. is a faculty member at Columbia Universityâ&#x20AC;&#x2122;s Mailman School of Public Health, Director of Columbia Universityâ&#x20AC;&#x2122;s Eye Radiation and Environmental Research Laboratory, and the U.S. Director of the Ukranian American Chernobyl Ocular Study (UACOS). Dr. Kleimanâ&#x20AC;&#x2122;s research uses the human eye as a model system to study the effect of ionizing radiation and environmental exposures on human health. Following the March 2011 earthquake in Japan, Dr. Kleiman has been frequently asked to discuss the consequences of the radiation leak from the Fukushima nuclear plant and has been featured in various publications and media outlets including Science, PBS, and MSNBC. In past interviews, Dr. Kleiman has offered some stirring and thought-provoking insight on the health consequences of radiation exposure at Fukushima, and he has interestingly warned against overstressing the risks posed by the radiation leak.

But from a factual perspective, we need to know more, for example, about what the particular radionuclides are. Different radionuclides have different half lives. Radioactive iodine has a half life of 8 days, and in 3 months, it is essentially at a negligible level. Radioactive cesium has a half life of 30 years, and cesium is much more of a long term issue. It is not simply enough to say that a great deal of radioactivity was released. We need to examine the type of radionuclides and their eventual presence in the food supply and in humans.

Spotlight The ocean is huge in volume. While Fukushima involved a very large amount of radioactivity that was released at the site of the plant and the levels of radioactivity at the site of the plant were enormous, as we move further away from the plant, even in terms of hundreds or thousands of meters, the concentrations drop dramatically. And at much greater distances from the plant, the concentrations in the ocean drop even more.
the long-term health outcomes and risks are. These are usually long-term, and in some cases, lifetime studies. In my area of research, which involves studying the relationship between ionizing radiation and cataract, there are important studies that came out only a few years ago on the A-bomb survivors in Hiroshima and Nagasaki.

We also need to distinguish between nuclear workers who are working heroically at the plant right now and were exposed to relatively higher doses and the general population, which, by-and-large, has been evacuated and removed from areas of immediate exposure risk.

'U .OHLPDQ There are regulatory guidelines within each country that say: â&#x20AC;&#x153;This is a safe level of radiation in foodâ&#x20AC;? or â&#x20AC;&#x153;this is an unsafe level of radiation in food.â&#x20AC;? These guidelines vary a bit from country to country. But in general, these guidelines are set so that the threshold levels of radioactivity are well below anything that would cause human health concern. Most guidelines are based on yearly consumption. So for example, the total amount of radioactivity that you are permitted to be exposed to over a year might be set to 1 mSv per year, and another guidelineâ&#x20AC;&#x2122;s threshold (for a different NLQG RI H[SRVXUH FRXOG EH VHW WR P6Y SHU \HDU 6R XVing water as an example, via back-calculation based on avHUDJH LQWDNH RI ZDWHU SHU GD\ DQG D GD\ H[SRVXUH LI

As I said earlier, future research is dependent on good dosimetry. And more importantly, additional research on the human health risks from low-dose radiation exposure is desperately needed. The health authorities have set up radiation monitoring stations through the prefecture and throughout Japan, monitoring levels in the soil, in the water and in the food supply, and taking physical samples to look for the type and amount of radiation being dispersed. Individual nuclides have different biological effects. For instance, cesium accumulates in soft issue while iodine goes to the thyroid, where it can increase the risk of thyroid cancer. At present, cesium and iodine are the two radionuclides most pertinent to human health concerns. We are measuring radioactive incorporation in individuals, via measurements in human excretions, or by direct Geiger counter readings of radioactivity in the thyroid.

Spotlight you drink contaminated water at a given level for that long, you might exceed the regulatory guidelinesâ&#x20AC;&#x2122; threshold. That would pose a potential, long-term health risk to the population. So as a result, we wouldnâ&#x20AC;&#x2122;t allow food or water to be sold or consumed if it is above a particular level of radiation. Again, these are just regulatory guidelines. It does not indicate whether youâ&#x20AC;&#x2122;re going to get the disease or not.

'U .OHLPDQ The type of reactor at Chernobyl is a type of reactor that we do not currently use. No external containment structure was present at Chernobyl to prevent the release of radioactivity. At Chernobyl, there were two explosions that vaporized and ejected tons of highly radioactive material from the core of that reactor high into the atmosphere.

The quantity of radioactivity material released at Fukushima is far, far lower than that at Chernobyl. So the public health risk is much lower because the amount of material released was much smaller. As opposed to Chernobyl, Three Mile Island was on the opposite end of the spectrum. The radiation at Three Mile Island was contained in the reactorâ&#x20AC;&#x2122;s containment structure, so there was little radioactive release, with the exception of a relatively small planned release of gas to reduce pressure in the vessel.

How do you think Fukushima will affect new initiatives to develop nuclear power?
'U .OHLPDQ We are living in a world of risk: the water we drink, the food we eat, cigarette smoke, unsaturated fats, alcohol, and lifestyle choices. These all contribute to our lifetime risk for disease. We need to keep radiation risks in context. There is a disproportionate fear of radiation that needs to be evaluated and kept in perspective with respect to the other risks we face. I am not saying that we shouldnâ&#x20AC;&#x2122;t be respectful of ionizing radiation. But we need to view radiation with the same perspective as we view looking both ways when we cross the street, smoking a cigarette, drinking alcohol, and leading a sedentary lifestyle. 35
One of the prime environmental exposures that I study is ionizing radiation, but I am also interested in arsenic exposure as well as other potential DNA damaging, genotoxic events. We believe that the lens of the eye and the associated pathology of cataract is a good model for environmental exposure associated with DNA damage and misrepair, and that the pathomechanisms of radiation cataract are fundamentally similar to some of the molecular and cellular pathways associated with development of cancer in other tissues. Another area of my research revolves around the genetic basis of differential sensitivities to radiation. Hypothetically, if you had a hundred people with prostate cancer at the same stage and with the same treatments, ninety-nine might do well with radiotherapy and respond similarly. One will do poorly. Why? We believe that some individuals have particular genetic makeups that make them much more radiosensitive. Typically, these are genes involved with recognizing and repairing DNA damage and regulating progression through the cell cycle.
