Can’t pass it on: HIV treatment prevents transmission (fact sheet)

HIV cannot be passed on through sex when a person living with HIV is on treatment and the amount of HIV in their blood remains very low. When HIV treatment lowers the amount of virus in the blood to less than 200 copies per millilitre of blood, it is called viral suppression. When someone is virally suppressed, they cannot pass on HIV to others through sex. Viral suppression: Less than 200 copies/ml Viral load: Refers to the amount of HIV in the blood. Regular viral load testing every 4 to 6 months is the only way to know if an individual has reached viral suppression.
