National HIV Care Continua for Key Populations.

We reviewed published national HIV care continua for men who have sex with men (MSM), people who inject drugs (PWID), and female sex workers (FSWs) to track progress toward the 90-90-90 target. We searched the Internet, PubMed, surveillance reports, United Nations Programme on HIV/AIDS country reports, US President's Emergency Plan for AIDS Relief country/regional operational plans, and conference abstracts for the continua and graded them on quality. We found 12 continua for MSM, 7 for PWID, and 5 for FSW from 12 countries. HIV diagnosis, antiretroviral therapy coverage, and viral suppression varied between (1) 5% and 85%, 2% and 73%, and 1% and 72%, respectively for MSM; (2) 54% and 96%, 14% and 80%, and 8% and 68%, respectively for PWID; and (3) 27% and 63%, 8% and 16%, and 2% and 14%, respectively for FSW. Two countries, using data from national cohorts, were high quality. There are limited key population continua in the public domain. Of the few available, none have achieved 90-90-90. Improved monitoring and evaluation of key population continua is necessary to achieve the 90-90-90 target.
