Key Points Question What proportion of black African adults attending social and commercial venues in London, United Kingdom, have been tested for HIV in the past 5 years and what proportion are living with HIV—both diagnosed and undiagnosed? Findings In this cross-sectional study of 604 respondents, 51.0% of men and 52.7% of women had undergone HIV testing in the past 5 years. Of respondents who provided an oral fluid sample for anonymized HIV testing, 93.2% of women and 90.4% of men were HIV negative; among those testing positive, 56.3% of women and 40.9% of men self-reported as HIV negative or untested, indicating they were living with undiagnosed HIV. Meaning Despite ongoing campaigns to increase HIV testing in African communities in London, the fraction living with undiagnosed HIV remains unacceptably high; therefore, testing coverage must be enhanced to meet the HIV prevention needs of this group.
