List of countries by HIV/AIDS adult prevalence rate

The human immunodeficiency virus (HIV), which causes AIDS, varies in prevalence from nation to nation. Listed here are the prevalence rates among adults in various countries, based on data from various sources, largely the CIA World Factbook.
As of 2018, 38 million people are estimated infected with HIV globally.
The HIV pandemic is most severe in Southern Africa. Over 10% of all people infected with HIV/AIDS reside within the region. Adult HIV prevalence exceeds 20% in Eswatini, Botswana, and Lesotho, while an additional six countries report adult HIV prevalence of at least 10%. Outside Africa, the highest prevalence rate is found in the Bahamas (3.3%).
In absolute numbers, South Africa (7.2 million), followed by Mozambique (2.2 million), India (2.1 million) and Nigeria (1.8 million) had the highest HIV/AIDS number of cases by the end of 2019. While South Africa's large population of HIV-positive people is attributable to its high disease prevalence (17.3%, one of the highest in the world), Nigeria's is lower at 1.3%, with India's prevalence rate at 0.2%. However, countries such as Nigeria with high HIV rates above 1% are classified as having Generalized HIV Epidemics (GHEs) by UNAIDS, while India's prevalence is well below this threshold, with a prevalence lower than the US's and about the same as France.
On the other end of the spectrum, Svalbard is reported as having no cases of HIV/AIDS.
