2. Botswana
Adult prevalence rate: 25.16%
The number of people who are HIV/AIDS infected in this country goes up to 350,000, while the number of AIDS-related deaths is around 3,200. It is important to note that Botswana, the number two on our list of countries that have the most AIDS cases in the world was among the first countries to enable free antiretroviral treatment to its HIV-positive residents, making a significant decrease in AIDS-related deaths. Again, women are the most vulnerable category, since HIV prevalence rate among them is 20.8%, while it is 15.6% among men.
