This is the tenth AIDS Review published by the Centre for the Study of AIDS at the University of Pretoria. These Reviews have been regarded as some of the most critical and interesting writing on HIV and AIDS in South Africa. They are widely prescribed as core reading in university courses in the USA, the UK, Australia, India and Brazil. The latest Review, Magic, authored by Isak Niehaus and Fraser McNeill, looks at uptake of ARVs and the forces that come into play which determine how people and communities respond to the ‘magic’ of treatment – the physical effect on the body, as well as ‘supernatural’ effects.
