The cumulative number of estimated AIDS cases in the U.S. is estimated to be 1.8 million. Over 1.1 million people are estimated to be currently living with HIV in the U.S. About 50,000 people are infected with HIV in the U.S. each year, a number which has remained fairly steady over the last decade.
There were 36.7 million people living with HIV in 2016, up from 33.2 million in 2010, the result of continuing new infections, people living longer with HIV, and general population growth. Global prevalence (the percent of people ages 15-49 who are infected) has leveled since 2001 and was 0.8% in 2016 (Figure 1).
