An antiretroviral drug is showing promise in the fight to eliminate AIDS by drastically reducing the odds of contracting HIV when taken before and after sex.
According to a new study published by the New England Journal of Medicine on World AIDS Day Tuesday, study participants who took the antiretroviral drug Truvada prior to, and following sex were 86 per cent less likely to contact the virus compared to those who took a placebo.
The study looked at 400 gay men and transgender women at high-risk of HIV transmission. The high-risk group was defined as people who had unprotected anal sex with two or more different partners within a six-month period.
