HIV in the United States by Region: Viral Suppression
Viral suppression is one of the six Ending the HIV Epidemic in the U.S. indicators. Viral suppression refers to the percentage of people with diagnosed HIV who have less than 200 copies of HIV per milliliter of blood.


It is important for people to know their HIV status so they can take medicine to treat HIV if they have the virus. Taking HIV medicine every day can make the viral load undetectable. People who get and keep an undetectable viral load (or remain virally suppressed) can stay healthy for many years and will not transmit HIV to their sex partners.

Data for 2020 should be interpreted with caution due to the impact of the COVID-19 pandemic on access to HIV testing, care-related services, and case surveillance activities in state and local jurisdictions.
