The demonstration of the efficacy of antiretroviral therapy (ART) for HIV prevention in heterosexual HIV serodiscordant couples has resulted in the call for widespread implementation of “Treatment as Prevention” (TasP) to confront the challenge of continued transmission of HIV. In addition, evidence of the possible effect of use of ART on decreasing the incidence of tuberculosis (TB) in persons living with HIV has also contributed further enthusiasm. Mathematical modeling studies evaluating the potential impact of TasP on the trajectory of the HIV and TB epidemics have inspired discussions about a possible future without AIDS. We present the evidence regarding the effect of ART on the incidence of HIV and TB, benefits and risks associated with embracing TasP, and the need for multicomponent prevention strategies and for further research to generate empiric data on the effect of TasP on HIV and TB at a population level.
