New research suggests an HIV-positive person taking drugs to treat the virus that causes AIDS may be able to have unprotected sex without fear of passing on the deadly virus.
A study published by the Journal of the American Medical Association found that nearly 900 HIV-positive people using antiretroviral drugs who reported having unprotected sex with their partners didn't pass on the virus, Science Daily reports.
When researchers followed up a year later, none of the partners had conclusively gotten HIV from their partners (though 11 were infected in other ways).
Scientists still urged people to take caution with HIV-positive partners. Doctors Eric Daar and Katya Corado wrote that the virus should be suppressed by the medicine at least six months before anyone could assume any level of safety.
"Even though the overall risk for HIV transmission may be small, the risk is not zero.
The researchers added that gay couples may be at higher risk than heterosexual couples.
Months ago, Charlie Sheen admitted to having unprotected sex while HIV-positive. Sheen's ex-girlfriend told Entertainment Tonight she slept with him knowing just that, and didn't seem disturbed.
