ART significantly extends the likelihood of surviving for several decades, according to the U.S. Department of Health & Human Services. If untreated, HIV-positive persons typically live in clinical latency for around 10 years. Individuals on ART are not likely to have their HIV infection reach the AIDS stage. If the viral infection progresses to that stage, survival is estimated at around three years.
