In her view, this landmark development could help end the HIV pandemic by preventing the virus’ transmission in high-risk populations.
The study, published in the Lancet medical journal on Thursday, considered the risk of HIV transmission between serodifferent gay male couples – where one partner is HIV-positive and one is HIV-negative — who do not use condoms.
About 1,000 gay male couples who had sex without condoms — where one partner had HIV and was taking antiretroviral drugs to suppress it — were assessed and the results showed that the treatment can prevent sexual transmission of the virus.
The study found no cases of HIV transmission within the couples even after eight years of following up with them.
The researchers estimate that the suppressive antiretrovial treatment prevented around 472 HIV transmissions during the eight years.
