In South Africa, men are less likely than women to know their HIV status or take antiretroviral treatment and often experience higher mortality. This 3-minute animated video describes a study led by the Desmond Tutu Health Foundation and UPenn which found that peer-delivered messaging about HIV being untransmissable if undetectable when on treatment (U=U) increased men’s HIV testing uptake. The study showcases the hallmarks of a BIT project: a rapid, low-cost intervention built upon an existing program and utilising a rigorous study design.
