"At yearend 2021, an estimated 11,810 persons in the custody of state and federal correctional authorities were known to be living with HIV, a decrease of about 2% from yearend 2020 (12,060) (figure 1).1 This decrease followed the largest 1-year decline (down 15% between 2019 and 2020, largely as a result of the COVID-19 pandemic) since data collection began in 1991. The population of state and federal prisoners living with HIV has fallen for 23 straight years from its peak of 25,980 in 1998, largely due to a roughly 4% average annual decrease in state prisoners with HIV."
