HIV Treatment Protects Uninfected Partner From the Virus

HIV Treatment Protects Uninfected Partner From the Virus HIV Treatment Protects Uninfected Partner From the Virus HIV treatment prevented transmission of the virus in gay couples when only one partner had the virus, a new study shows. The research included 358 such gay couples in Australia, Brazil and Thailand. The HIV-positive partners received treatment that reduced the amount of virus in the blood to undetectable levels. The participants were followed from 2012 to 2016. During that time, the couples reported nearly 17,000 instances of anal intercourse without a condom. None resulted in HIV transmission, the study authors said.
