The extent of the devastation that Nigeria’s anti-gay law is wreaking on Nigerian anti-AIDS efforts is coming into view.

Among Nigerian men who have sex with men, the number of people reached for HIV prevention has dropped drastically since the signing of the anti-gay “Same-Sex Marriage Prohibition Bill” in January. According to a survey of five anti-AIDS organizations in five Nigerian states, HIV prevention contacts (using UNAIDS’s Comprehensive Minimum Prevention Package Intervention) are:

Down 40 percent in Lagos state
Down 30 percent in Rivers state.
Down 10 percent in Cross River state.
Down 30 percent in Abuja (Federal Capital Territory).
Down 70 percent in Kano state.
