Diagnoses of HIV Infection in the US, 2019

"From 2015 through 2019 in the United States and 6 dependent areas among all adults and adolescents, the annual percentage of diagnoses of HIV infection among adults and adolescents attributed to male-to-male sexual contact (MMSC) accounted for over 65% of diagnoses (Figure 5 and Table 1b). In 2019, diagnoses of HIV infections attributed to MMSC (approximately 70%, including 4% MMSC and injection drug use [IDU]) and those attributed to heterosexual contact (23%) accounted for approximately 93% of diagnoses in the United States (Figure 6). Among male adults and adolescents, the annual number of diagnosed HIV infections attributed to MMSC decreased and the number attributed to heterosexual contact decreased (Table 1b). The number of infections attributed to IDU and MMSC and IDU remained stable. The perinatal and “Other” transmission categories accounted for less than 1% of cases. Among female adults and adolescents, the number of infections attributed to IDU increased. The number of infections attributed to heterosexual contact decreased. The perinatal and 'Other' transmission categories accounted for less than 1% of diagnoses."
