HIV/AIDS

In the decades that followed the start of the epidemic, the progress in the treatment and prevention of the Human Immunodeficiency Virus (HIV) has been substantial. Still, the epidemic is not over. Too many new infections still occur, in specific populations that are at consistently higher risk of acquiring HIV. They are what UNAIDS call key populations (e.g., sex workers, men-having-sex-with-men). Also, in many countries in sub-Saharan Africa, the epidemic is generalized in the population, with new cases being particularly high among young women.

Here, we

• study how mobility and migration patterns drive the risk of HIV acquisition where the epidemic is generalized,
• evaluate strategies to offer HIV prevention and how they could be made more effective,
• study the effect of the complex interplay between HIV prevention, HIV treatment and circulation of other sexually transmitted infections.
