Biomedical research has given us powerful new tools to prevent HIV transmission. Those at very high risk for getting HIV can take PrEP, a daily pill that greatly reduces their chance of getting HIV. People who have been exposed to HIV can take PEP, medicine that can reduce the chance of becoming HIV-positive, if started within 3 days of exposure. Furthermore, treatment for those who have HIV infection, called ART, is now a proven prevention strategy. CDC has identified the best practices and most effective prevention strategies in the Compendium of Evidence-Based Interventions.
