HIV Testing Pre- and Post-COVID-19 Pandemic Among Persons who Inject Drugs - National HIV Behavioral Surveillance, 19 Cities, 2018 and 2022.

HIV testing decreased during the COVID-19 pandemic among persons who inject drugs (PWID), though it is unclear how these changes in HIV testing affected different sub-groups of PWID. We estimated the change in past-year HIV testing between 2018 and 2022 overall and by sociodemographic and health care characteristics among PWID. Past-year HIV testing significantly decreased between 2018 and 2022 overall and across most sub-groups of PWID, including PWID accessing and not accessing medical and harm reduction services. Integrating HIV testing across medical and harm reduction services accessed by PWID and expanding community-based HIV testing might increase HIV testing among PWID.
