Dear all, Some weeks ago I walked across two bill boards at the Central Station in Utrecht, The Netherlands and I stopped myself for a few seconds to have a closer look. One of the bill boards was a commercial by our national Health Centre saying ‘Can you recognize a malaria mosquito?’ The other one was by the Food Safety Centre and it was showing two delicious looking meals while stating ‘you don’t see the pathogens’. Public health and food safety are in our everyday lifes and I once more realized how big of a role vets can play in tackling these human health risks, since 70% of pathogens arise from an animal source. We can do this following the One Health spirit and applying a coordinated, collaborative, multidisciplinary and cross-sector approach to address potential or existing risks that originate at the animal-human-ecosystems interface. Known and unknown disease pathogens pop up everywhere on our planet, on top of that globalization and increased traveling have made it easier for pathogens to spread faster and further. The ebola crisis is still fresh in our minds and there is always a significant risk of new emerging infectious disease outbreaks. The IVSA brings together veterinary students from over 50 countries worldwide. I feel that together we build a powerful network that is able to fight public health issues, both locally and globally. The Veterinary Public Health Journal is compromised by students and brings up some of the latest trends and events in the field of Public Health. In this issue the main focus is on rabies, the zoonotic disease with the highest fatality rate after the onset of clinical signs. Also various other veterinary public health related topics will be covered in this edition of the journal. Enjoy! Best regards, Caroline Publications Team member - Standing Committee on One Health 2015-2016

Veterinary students normally should have received rabies pre-exposure prophylaxis and therefore can be involved in the actual injecting and handling of animals while other students could be more involved in (organizational) aspects of a vaccination campaigns. I worked with students during my time in both Zambia and Mozambique where we held big rabies drives. We mixed teams of older and younger students to allow the exchange of knowledge within the student group. The students were vital by going on radio and speaking the local language to explain rabies, but also by making and helping connect with the local communities during the actual vaccination days. I also advocate for not sticking to the health care profession of students but look beyond the border to business students who can help with the cost benefit or students involved in mass-media and communication. 7.

Students involved in the fight against rabies Report from the vet students of Ibadan, Nigeria
By Mogbojuri Oluwatobi A (Local Chairman Organizing Committee, World Rabies Day 2015)
The International Veterinary Students Association (IVSA) Ibadan Chapter organised a 3-day event on the occasion of World Rabies Day on the 29, 30 September and 10 October 2015. The events were focussed on creating awareness, spreading information on rabies and fighting the disease by vaccinating dogs and cats.
On the first day we had organized a public seminar on rabies at our own university (University of Iba-
dan, Nigeria). Students and all other inhabitants of Ibadan who were interested in joining the seminar were invited. Around 600 people attented the seminar.
On the second day seminars for three secondary schools in the area were given on â&#x20AC;&#x2DC;the zoonotic impli-
cations of rabiesâ&#x20AC;&#x2122;. The main goal was to educate the public on rabies transmission and possible prevention and control measures to be taken. Another important goal was to make the communities aware of the free VPH Journal 5th edition

vaccination programme being offered by the IVSA Ibadan Chapter. A lot of secondary school students attended this day. During the evening session of day 2 an awareness rally took place at a rural area, Egbeda Local Government, Ibadan, Oyo State, Nigeria.
On day three there was the awareness rally in Egbeda Local Government (Bankesa, Erunmu, and Oree),
which is a typical rural community. The awareness rally was aimed to sensitize the community and educate them on the importance of rabies prevention and control and so why their dogs should be vaccinated. We communicated with them one on one. We tried to answer as many questions as possible, because the majority of the population does not understand what rabies is exactly and how to prevent the disease from spreading further. We were able to talk to them in their own language, which ofcourse was a really great advantage.
Rabies is known as “aja digbolugi” in the Yoruba Language which means “mad dog”, literally it means “dog
that bites trees or that hits a tree with his head”. This is similar to the furious form of rabies and the name is based on the clinical manifestations in dogs affected with the rabies virus.
Finally, the vaccination activities took place on the 10th of October in the same rural area. Twohundred lo-
cal strain anti-rabies vaccines were offered by the Nigerian Veterinary Research Institute (NVRI). Dogs and cats of various species ranging from our indigenous breeds to exotic breeds were vaccinated. Additional veterinary services such as deworming, treatment for ectoparasites and advice on pet management and health care practices were carried out as well. It was a great event an hopefully we have more to follow!

Milk, the public and economic disaster of Sri Lanka SRI LANKA DAIRY FARMING INDUSTRY VS. MILK POWDER PRODUCTION
Taylor Calloway, US Davis University of Carlifornia, School of Veterinary Medicine, IVSA SCOH Official Member Sri Lanka is an island nation located south of India. The country is known for its rich farming culture of tea and rice plantations. These practices are a vital part of family income and food consumption throughout the nation. Livestock farming is also a practice among the people and provides the main intake of multiple protein sources such as chicken, fish and cattle meat or products. Unfortunately, Sri Lanka is not self-sufficient in its dairy industry, requiring a supplementation of imported powdered and condensed milk products. Local demand of milk requires 70% of outsourced products from other countries (Perera et al, 2008). Most recent statistic studies report the cost of imported products to be Rs 27 billion annually (Ministry of Social Services, Welfare and Livestock Development, 2012). The amount tops the list of one of the largest country expenditures. The Department of Census and Statistics in Sri Lanka reported in the 2012/2013-year, the average household expenditure was Rs. 41,444 monthly. Over a third (Rs. 15,651) of the monthly expenditures were spent on food consumption. The Sri Lankan residents consume rice, wheat flour and bread in the largest VPH Journal 5th edition
17
quantities. This aspect places them at the top of the greater food expenditure list. However the largest expenditure on a protein source is powdered milk by the national household expenditure decile of 2012/2013year.

There are various explanations for the countries need of imported powdered milk products. The reasons include but are not limited to political, technical and socio-economic factors, and a low farm gate price (Perera et al, 2008). The Ministry of Social Services, Welfare and Livestock Development had plans in 2009 to increase the country’s milk production (240 million) 300 times by the end of 2015. The plans included improvement in policy support, developmental programs, research, disease control, and strategies to improve breeding, production, marketing, industrial development and social aspects. In the past ten years, there has been an increase in the country’s own milk production and consumption. Although there is improvement in the years, there is still a high demand for more planning, implementation of new strategies, and sustainability of these ideas for the dairy industry in Sri Lanka to succeed. One Health is a multidisciplinary topic that covers many aspects in the communication between human, en vironmental and animal health. There are many opportunities to use One Health strategies in issues involving local or global health. The example of Sri Lanka’s dairy industry is multifaceted with disease issues, cul-
18
VPH Journal 5th edition
tural necessities, nutritional implications within both animal and human sides and economical problems. These all require a team of diverse specialists to work together and organized large, detailed policies to set Sri Lanka up for success. So when you think of One Health, remember that it is to solve problems to promote the health of all.

world where everything from economy to health care is trending towards globalization. However, we need to develop a better understanding of how the environmental component impacts animal and human health. By using the One Health approach, all three areas, human, animal, and environmental health, will be improved and stabilized. In addition, concerns about antibiotic resistance, zoonotic pandemics, and anti-helminthic resistance (which has a huge environmental component) will likely have a significant impact on the ability of general veterinary practitioners to prescribe drugs that we currently take for granted â&#x20AC;&#x201C; either because the drugs are no longer effective or because of legal restrictions. One Health Consulting hopes to implement protocols to demonstrate that veterinary professionals and animal industries are being proactive in preventing not only antibiotic resistance, but also transmission of contagious disease agents between people, animals and the environment.

World veterinary day is an event to remind peo-
ple about contribution of veterinary profession to the many aspects of life, an important one being the health of both human and animals. This year, world veterinary day appointed an emerging issue as a theme: Vector Borne Diseases.
Vector borne diseases are becoming a major
public health issue worldwide. In the past time, vector borne diseases were known as infections in tropi-
“Rise of earth temperature is one of the reasons mosquitoes can impenetrate subtropical areas”
cal areas, but today the infections may spread into subtropical areas. There are many contributing factors driving this emergence. These factors include but are not limited to the destruction of habitat, changing ways in farming primarily in developing countries, and human invasion and encroachment and climate
change. All of these things caused an imbalance among host, agent and environment. A destroyed environment can lead to a number of other issues including global warming. Rising of the earth’s temperature is one of the reasons why mosquitoes can impenetrate subtropical areas. Mosquitoes usually cannot sustain their life in low temperature zones, but as the temperature rise mosquitoes can adapt and prolong life.
One very important vector borne disease is Chikungunya. Chikungunya is a viral zoonotic di-
sease caused by Chikungunya virus infection. Chikungunya was first isolated in Tanzania in 1952 from a patient. The word “Chikungunya” comes from the Kimakonde language (an ethic language of Tanzania), and means to become contorted. Before 2000, Chikungunya outbreaks were very rare. Since 2000, Chikungunya outbreaks have emerged frequently. In 2000, there was a large outbreak happened in Democratic Republic of Congo, while another outbreak happened in Indonesia in 2001 to 2003. In addition, Kenya suffered Chikungunya outbreak in 2004. Comoros Island and India suf32
VPH Journal 5th edition
“Chikungunya is not treatable but preventable” fered Chikungunya outbreak in 2005 and 2007 respectively. Until 2015, Chikungunya fever has been identified in 60 countries in Asia, Europe, Africa, and America.
As was mentioned earlier, the cause of Chikungunya Fever is Chikungunya Virus. Chikungunya
is an RNA virus, genus Alphavirus, Family Togaviridae. Chikungunya is transmitted through Aedes, mosquito bites. Two species of Aedes, A. aegepty and A. albopictus, were known to be able to transmit the virus to vulnerable hosts. The mosquitoes are active primarily during the day, and humans are one of Chikungunya virus’ hosts. In Africa, Chikungunya virus was found in Bats and Non-human primates.
When an infected mosquito bites, the virus penetrates the body and enters blood stream, the
virus will start to infect cells and replicate rapidly. After 3 - 7 days after mosquito bite, symptoms most likely will start to emerge. In humans, some common symptoms of Chikungunya include fever and severe joint pain, and sometimes other symptoms can appear like headache, muscle pain, joint swelling and rash. The symptoms will emerge after 3 to 7 days after being bitten by infected mosquitoes. At this stage, the virus can be found in the victim’s blood and the infected individual may transmit the disease to other people through a mosquito bite. When a human is infected, transmission of other vector borne diseases may occur (for instance dengue), so if you are infected by Chikungunya, you must protect yourself from mosquito bite because you’re the source of new infection. Usually sick people will get better within a week, painful joints may remain for months but death is rare.
Chikungunya is not treatable but preventable. So far there is neither vaccine nor medication ap-
proved for treating Chikungunya. We can prevent the infection by avoiding mosquitoes bite. Mosquitoes, especially Aedes, are active aggressively during daylight. It is highly recommended to use insect repellent before you go out during the day. If you stay in the room, make sure the door and window are always closed and use air conditioning if possible. You can also use insecticide spray to secure the room, wear long sleeved shirt and long pants. The other method to prevent the infection is by terminating life cycle of mosquitoes. In wet season or rain season, check items that may hold water around houses, if you find them you have to empty, throw out, bury or at least turn them over so they will not contain water any longer. Aedes have tendency to lay their eggs in fresh water so by doing this, it may help to cut their life-cycle.
We can prevent Chikungunya fever more further by spreading this information to your peers
and fellows to increase public awareness. Many diseases can be avoided by taking preventing actions, so make sure to take care of yourself and others. VPH Journal 5th edition

IVSA Policy Statement Antimicrobial Resistence Week
During the week of 17-22 November 2015, for the first time, the World Health Organization (WHO) held an Antimicrobial Resistance (AMR) week in recognition of this growing international problem. The WHO is making a massive step forward to highlight the immense global danger that AMR presents. Their campaign aims to increase worldwide awareness of antimicrobial resistance and to encourage best practices among the general public, health workers and policy makers to avoid the further emergence and spread of antibiotic-resistance (1). Put eloquently by Dr. Margaret Chan, the Director-General of the WHO, “Antimicrobial Resistance is not a future threat looming on the horizon. It is here, right now, and the consequences are devastating.” To put this in perspective, there have been no newly developed classes of antimicrobial drugs for about the past 30 years. Bacterial virulence factors are continuously gaining advantage over our outdated antimicrobials, leading to more infection and disease paired with increased mortality. The dramatic rise of AMR in recent times can be attributed to two main causes: •
The limitless and incorrect usage of antimicrobials by a variety of health professionals
•
The generalized lack of compliance by patients, owners and users of antimicrobials in regards to the
appropriate manner in which to use these medications.
The veterinary field has recently come under intense pressure to limit the use of antibiotics in multiple areas, especially concerning livestock. By enforcing regulations on the use of antimicrobials in food animals, there is an attempt to decrease residual levels of antibiotics found in meat for human consumption. There are copious amounts of scientific research showing that antibiotic use in livestock contributes to AMR spread in humans, due to these drug residues (2). Thus, the IVSA calls that all veterinary students should be well informed about this issue of increasing AMR and should be actively involved in halting its progression. Students must have the ability to accurately inform animal owners about the risks of using antimicrobials, as well as to highlight the importance of following prescriber instructions. It is imperative that students clearly guide owners to follow directions and use the appropriate dosage and duration for their animals. Veterinary students must work to correctly diagnose patients and limit the use of antimicrobials for use only in those that genuinely benefit from them. As future veterinarian, students should avoid regarding antimicrobials as the panacea of all diseases. 34
VPH Journal 5th edition
To achieve all of these goals, we need a change in the veterinary curriculum. The educational system must give students the opportunity to better educate consumers, allowing students to have the proper tools for guiding clients and educating owners on the importance of appropriate use of antimicrobials. The veterinary curriculum should also give future veterinarians the ability to correctly prescribe antimicrobials, and to stress the seriousness of limitless use. Proper usage of antimicrobials should be well understood and followed by veterinarians, and this usage should be based on clinical proof of active bacterial infection, as well as guided by antibiograms and susceptibility tests where possible.

IVSA Policy Statement International Students Day
On this day, November 17, the International Veterinary Studentsâ&#x20AC;&#x2122; Association (IVSA) congratulates the numerous people across history that have stood up for the rights of students: from Jan Opletal in 1939, to the strike in Athens in 1973, to the Velvet Revolution in Prague in 1989, to the recent shutdown of tertiary education in South Africa, to the hundreds of thousands of students in the Netherlands who stood up in the name of a free, fair education for all. As veterinary students, we know and understand the pain and stress placed on students as they make their way through their veterinary education, and in particular the pressure they feel due to concurrent financial strain. In many countries, veterinary education is one of the most expensive degrees to pursue. This high cost of education not only places a great stress burden on students, but it can also prevent many students from achieving their dreams of becoming a veterinarian if they cannot afford to appropriately further their education or even afford it at all. There is an increasing demand for veterinarians due to a changing global perception of a veterinarianâ&#x20AC;&#x2122;s role in the betterment of human health following One Health principles, and the consequences of the financial burden of student education might soon result in the veterinary community not being able to cater to these demands. However, the cost of education does not solely have a negative impact on academic pursuance and development. Studies have shown that veterinary students experience depression more often than human medical students, with up to one third of first-year students showing symptoms of depression, in one US study (1) financial stress burden are less likely to be involved in campus life and instead, focus solely on their academic studies in fear of failing out (2) variety of problems, but perhaps, more importantly, does not foster adequate communication and social skills for a veterinary graduate to fit appropriately into society. Especially in a profession that requires a high level of social engagement and empathy with clients, this can have devastating effects in the work field, in turn, leading to a decrease in work satisfaction and an increase in work-related stress. With the rising size and number of student loans required to achieve degrees, the financial burden does not end once a student has graduated. Veterinarians, who study on average for 6 years, earn much less money as compared to many other academic professions with a comparable degree. Many students find it impossible to combine the stress and lengthy hours of their education with a stable job during their veterinary studies, and are therefore left to start paying their debts as soon as they graduate and begin their working life. Although starting 36

salaries have increased over the years, educational debt has proportionally increased at a much greater rate (3). The veterinary degree has a very high debt-to-starting-salary ratio, which forces recently graduated veterinarians to face a very difficult first few years in their working lives as they struggle to pay off a loan that has accumulated over a considerable time. This adds much stress to veterinarians who are also dealing with being placed in highly emotional situations on a daily basis during the work day, and contributes to why the veterinary profession has one of the highest suicide rates across the world (4). The IVSA, a global body representing over 30,000 veterinary students around the world, therefore calls on students and places of tertiary education to work together in decreasing the cost of veterinary education while maintaining high standards and excellent quality. We call on these institutions to work towards a model of free veterinary education to allow all students the ability and chance to achieve their goal of one day being high-quality and stress-free veterinarians. We therefore call on the global community of students to stand together to demand free, fair and quality education for all. References: 1.
