Successful treatment is “as effective as consistent condom use” in reducing HIV transmission

At least, for vaginal sex…(no data on anal sex!)

The statement notes that there is now conclusive randomised clinical trial evidence, from the HPTN 052 trial, to show that transmission of HIV through vaginal sex is significantly reduced when an HIV-positive person is taking effective antiretroviral therapy (ART). In this trial, early treatment reduced HIV transmission to an uninfected partner by 96%.
