Globally, new HIV infections are concentrated in eastern and southern Africa where the infections are largely acquired by women outside of known key populations. Identifying African women at high risk for HIV acquisition and successfully engaging them in HIV prevention services, particularly pre-exposure prophylaxis (PrEP) programs, is an urgent global health priority.

However, these tools have low to moderate sensitivity, missing many women at high risk for HIV. This is partly due to underreporting of risk factors, but also because many African women are at heightened HIV risk solely through relationships with high-risk male partners. Moreover, many African women enrolled into PrEP programs stop using Pr
