Prevention of HIV


The World Health Organization publishes a set of comprehensive guidelines to the prevention of HIV and AIDS; the most recent version was published in 2010. I’ve tried to distill down the 174-page document here. It’s especially interesting to see how treatment and prevention come together as research has demonstrated that ARV treatment reduces the risk of transmission.

Know your HIV status
·       Client-initiated HIV testing and counseling
·       Provider-initiated HIV testing and counseling
·       Blood donor HIV testing and counseling
·       Laboratory support

Prevent sexual transmission of HIV
·       Promote condom use

·       Risk reduction counseling

Prevention in childbearing women, infants, children
·       Family planning, counseling, contraception
·       ARV treatment in pregnancy to prevent infection in infants
·       Education and support for women living with HIV and their children and families

Treatment scale-up
·       Intervene to prevent illness
o   Cotrimoxazole prophylaxis (vs. PCP and toxoplasmosis)
o   Prevent fungal infections
