The Human Immunodeficiency Viruses (HIV) are two species of Lentivirus (a subgroup of retrovirus) that infect humans. Over time, they cause Acquired Immunodeficiency Syndrome (AIDS), a condition in which progressive failure of the immune system allows life-threatening opportunistic infections and cancers to thrive. Without treatment, average survival time after infection with HIV is estimated to be 9 to 11 years, depending on the HIV subtype.
An estimated 2.1 million people were living with HIV in Latin America and the Caribbean in 2017 (1.8 million in Latin America and 310,000 in the Caribbean). This equates to an HIV prevalence of 0.5% in Latin America and 1.2% in the Caribbean. In the same year, there were 100,000 new infections in Latin America and 15,000 in the Caribbean, and 47,000 people died from AIDS-related illnesses (37,000 in Latin America and 10,000 in the Caribbean). - Avert.org
West and Central Africa is home to 5 million people living with HIV, of whom 450,000 are children. HIV prevalence among adults is 1.5%, which is relatively low when compared to East and Southern Africa. There is wide variation between countries, ranging from 0.2% in Mauritania to 7.1% in Equatorial Guinea. - Avert.org
East and Southern Africa is the region hardest hit by HIV. It is home to around 6.2% of the world’s population but over half (54%) of the total number of people living with HIV in the world (20.6 million people). In 2018, there were 800,000 new HIV infections, just under half of the global total. - Avert.org
