Guidance on oral pre-exposure prophylaxis (PrEP) for serodiscordant couples, men and transgender women who have sex with men at high risk of HIV Recommendations for use in the context of demonstration projects

These recommendations have been developed specifically to address the daily use of antiretrovirals in HIV-uninfected people to block the acquisition of HIV infection. This prevention approach is known as pre-exposure prophylaxis.

At this stage evidence is available from studies with two groups: men and transgender women who have sex with men; and serodiscordant heterosexual couples. In parallel, WHO also is preparing new recommendations on the use of antiretroviral drugs in people living with HIV to prevent transmission of infection.
