HIV Treatment Can Prevent Sexual Transmission
People with HIV should take medicine to treat HIV as soon as possible to Improve their own health, and Prevent transmitting HIV to other people.
HIV medicine can reduce the amount of HIV in the blood (also called viral load).
HIV medicine can make the viral load so low that a test can’t detect it. This is called undetectable viral load. Having an undetectable viral load (or staying virally suppressed*) is the best thing people with HIV can do to stay healthy. If their viral load stays undetectable, they have effectively no risk of transmitting HIV to an HIV-negative partner through sex.
