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.
How long can or does the HIV virus remain dormant in the Human Body before it becomes AIDS virus? For the majority of patients who have HIV, the dormancy period lasts about 10 years.

It is estimated that another 5 percent to 10 percent of patients will not reach the AIDS phase for more than 15 years.
