Ninety percent of the world’s HIV-infected population lives in developing countries, and women and children are among the hardest hit. The global health community has worked hard to hone best practices in the fight against HIV/AIDS at the facility and community levels. Key interventions include: prevention of mother-to-child-transmission and medical transmission of HIV; counseling and testing; voluntary medical male circumcision (for prevention); and care and treatment (e.g., antiretroviral therapy, opportunistic infections, palliative care). Great strides are also being made in integration of HIV/AIDS services with other interventions (TB, family planning, etc.)—to reach as many people as possible.
