Without treatment, what is the estimated life expectancy for someone diagnosed with AIDS?

The estimate of three years as the life expectancy for someone diagnosed with AIDS without treatment is based on historical data and research findings. Individuals with AIDS experience a severely compromised immune system due to the progression of HIV, which leads to increased susceptibility to opportunistic infections and certain cancers.

Prior to the availability of effective antiretroviral therapy (ART), life expectancy for untreated individuals diagnosed with AIDS was often estimated around this timeframe. It's important to note that these estimates can vary depending on various factors such as the individual's overall health, the presence of co-infections, and access to healthcare.

Advancements in treatment have significantly improved the prognosis for individuals living with HIV/AIDS. With ART, many people live long and healthy lives. However, the specific question focuses on the situation without treatment, emphasizing the severe impact of AIDS on life expectancy in the absence of medical intervention.
