NEW YORK — Taking drugs for treating HIV might reduce the risk of infection among heterosexual couples, according to two new studies conducted in Africa.
One study, funded by the Bill & Melinda Gates Foundation and conducted among 4,758 couples in Kenya and Uganda, found that when taken daily, Gilead’s Viread (tenofovir) reduced the rates of infection by at least 62% compared with placebo. Truvada (tenofovir and emtricitabine), another drug made by Gilead, reduced infection risk by 73%.
