This graphic highlights the different burden of new HIV infections among key populations (sex workers, people who use drugs, men who have sex with men, transgender people and prisoners) and their partners across regions
The Middle East and North Africa has one of the lowest HIV prevalence rates in the world, at 0.1%. It also has the lowest antiretroviral treatment coverage of any region, with only 24% of adults and 27% of children receiving treatment in 2016.
Nigeria has the second largest HIV epidemic in the world, with 3.2 million people living with HIV in 2016. However, the country's large population means that this equates to a relatively small prevalence rate compared to some East and Southern African countries, of 2.9% in adults.
Zimbabwe has the fifth highest HIV prevalence in Sub-Saharan Africa, with 1.3 million people living with HIV. AIDS-related deaths, however, have more than halved since 2013, from 61,000 in 2013 to 30,000 in 2016.
