Most medical students go overseas on their electives—97% from one medical school— and many go to Africa. The attractions are obvious: adventure, travel, new cultures, and a depth and range of medical experience that may never be gained at home. However, like any travel experience, electives can be dangerous. British medical students doing electives overseas often go to areas with high HIV prevalence, work in settings with poor infection control practices, and are exposed to HIV and other bloodborne viruses. The reports by Moss and Beeching (p 161) and Gamester et al (p 158) in this week's issue provide shocking data that help to quantify these concerns.
