Swaziland, a small landlocked country in southern Africa, has the highest HIV prevalence in the world, with 28.8% of their adult population living with HIV. In 2015, 11,000 people were newly infected with HIV and 3,800 people died of an AIDS-related illness.1.
Lesotho is one of the countries hardest hit by HIV, with the second highest HIV prevalence after Swaziland.1 HIV prevalence was 25% in 2016, and has been around this level since 2005.2 An estimated 330,000 people were living with HIV in Lesotho and 9,900 died from AIDS-related illnesses in 2016.3 Overall, HIV incidence is declining, from 30,000 new infections in 2005 to 21,000 new infections in 2016.
Botswana is still one of the countries most affected by HIV in the world, despite its provision of universal free antiretroviral treatment (ART) to all people living with HIV. Botswana’s HIV epidemic is firmly established in the general population, with women and young women disproportionately affected.
Malawi has one of the highest HIV prevalences in the world despite the impressive progress the country has made in controlling its HIV epidemic in recent years. Young people are particularly at risk, due to early sexual activity and marriage, with 50% of new HIV infections affecting those aged 15 to 17 in Malawi.
Additionally, CDC-Tanzania supports studies to understand the impact of HIV in people who inject drugs, female sex workers, and men who have sex with men (MSM). CDC supports testing, prevention, and linkage to care and treatment services for key populations.
Nigeria is one of ten countries that together are home to 80% of people living with HIV and TB co-infection.91 Low antiretroviral treatment coverage (30%) contributes to the high rates of HIV-associated TB in the country, as being on antiretroviral treatment dramatically reduces a person living with HIV’s risk of TB.
