Approximately 36.9 million people were living with the human immunodeficiency virus (HIV) at the end of 2017, the majority of them in sub-Saharan Africa. While there is no cure for HIV/AIDS, a combination of drugs, known as antiretrovirals (ARVs), enable people to live longer, healthier lives. The cost of first-line drugs are now cheaper than ever, but efforts are still needed to ensure everyone who is living with HIV receives treatment. Over 15 million people missed out on receiving treatment in 2017.
