From 2014 through 2018 in the United States and 6 dependent areas, among male adults and adolescents, the annual number of diagnosed HIV infections attributed to injection drug use increased (Table 1b). The number of infections attributed to male-to-male sexual contact and heterosexual contact decreased. The number of infections attributed to male-to-male sexual contact and IDU [Injection Drug Use] 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 cases."
