antiretroviral pills

In high-income countries like the U.S., the standard of care for people infected with HIV is to provide antiretroviral pills when the virus is found, even when there are no symptoms of AIDS. The strategy staves off the disease and has a second — big — benefit. It has been shown to prevent the spread of HIV in sexual encounters. It's called "treatment as prevention" (TasP in medical jargon), or "test and treat."
