9. Malawi
Adult prevalence rate: 10.04%
Around 980,000 people in Malawi, the next one on our list of countries that have the most AIDS cases in the world are HIV/AIDS infected, while the number of AIDS-related deaths is 27,000. Again, there is a huge disproportion in the number of infected people when it comes to men and women since HIV prevalence is 12.8% among women and 8.2% among men.
