Part 1: Summary
Sub-Saharan Africa has the highest prevalence of Human Immunodeficiency Virus (HIV) in the world (1). Spread through blood, sexual contact, and mother-to-child transmission, the virus attacks the immune system and its capacity to fight various diseases. After 2-5 years of HIV infection, individuals are at risk for the most advanced stage of the infection is Acquired Immunodeficiency Syndrome (AIDS). There is no cure for the infection, but a cocktail of at least drugs during in antiretroviral therapy (ART) can control viral replication. ART can also be used in prevention of HIV for individuals at risk.
