Undiagnosed and Untreated HIV Infection Among Persons Who Inject Drugs: Results of Three National HIV Behavioral Surveillance Surveys, San Francisco, 2009-2015.

We examined three waves of National HIV Behavioral Surveillance surveys of persons who inject drugs (PWID) in San Francisco to assess meeting UNAIDS 90-90-90 targets. Diagnosis of PWID living with HIV increased from 64.4% in 2009 to 80.5% in 2015. Antiretroviral treatment among those diagnosed did not improve (63.8% in 2009, 62.9% in 2015). Programs in San Francisco have not achieved the first two UNAIDS targets for PWID by 2015. In a context of a rising opioid epidemic, there is urgent need for increased case finding of PWID living with HIV who are undiagnosed with rapid linkage to treatment.
