No. A person living with HIV on antiretroviral therapy (ART) with an undetectable HIV viral load in their blood for at least six months has a negligible risk of transmitting HIV to a sexual partner. Negligible means: so small as to not be worth considering; insignificant. Therefore, HIV experts and health educators have described the transmission risk in public health communications as: "not transmittable", “no longer infectious”, "zero risk", "no infection risk", “do not transmit”, and “cannot transmit.”
