Science has confirmed that when a person living with HIV is undetectable, they’re not only healthier. they also cannot pass HIV to anyone else. Or, Undetectable = Untransmittable (U=U).
This is a landmark development in the history of HIV. It means that people living with HIV who are undetectable have no reason to fear passing on the virus to sexual partners. People living with HIV are a part of the solution to ending HIV just by taking the medicine they take every day to stay healthy.
