HIV prevalence

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 2009, it is estimated that there are 33.3 million people worldwide infected with HIV.

The HIV pandemic is most severe in Sub-Saharan Africa. Over 60% of all people living with HIV reside within the region. Adult HIV prevalence exceed 20% in Swaziland, Botswana, and Lesotho, while an additional six countries report adult HIV prevalence of at least 10%. In terms of raw HIV case numbers, South Africa has largest population living with HIV (6.3 million), followed by Nigeria (3.2 million), and India (2.1 million) by the end of 2013. While South Africa's large population of HIV-positive people is attributable to its high disease prevalence (17.3%, ranked highest in the world) and Nigeria is ranked 20th (3.7%), India's prevalence (0.3%) is comparable to Canada, the UK, and lower than the USA due to its large population (1.3 billion).

On the other end of the spectrum, Svalbard is reported as having no cases of HIV/AIDS, while Bhutan has a much larger population but still only an estimated 246 cases through 2011. Countries such as Afghanistan, and Cape Verde are reported to have the lowest prevalence of the disease, at less than 0.1% of their populations.
