Notice: Updating HIV Treatment and Viral Suppression Messages (September 7, 2017)
The goals of HIV treatment are to improve health and prevent transmission of HIV. The best marker of successful treatment is reducing the amount of HIV in the blood and elsewhere in the body to very low levels. This is called viral suppression. Three different studies of the prevention effectiveness of viral suppression to reduce the risk for sexual HIV transmission have shown similar results: across thousands of couples and many thousand acts of sex without a condom or PrEP, no HIV transmissions were observed when the HIV-positive person was virally suppressed. This means that getting and staying virally suppressed is not only the best thing people living with HIV can do to maintain their health, but also one of the best ways to prevent new infections through sex. CDC is working with other federal agencies to ensure that we consistently and accurately describe the prevention effectiveness of HIV treatment and viral suppression for sexual transmission of HIV. We will update our messages accordingly.
