The average duration of HIV asymptomatic infection is 8-10 years.
AIDS is caused by HIV infection and is clinically divided into three phases: the acute HIV infection phase, the asymptomatic HIV infection phase, and the AIDS phase. Without treatment, the average duration of asymptomatic HIV infection is 8-10 years, which can be as short as a few months for those with rapid disease progression or up to 20 years for those with milder disease. If aggressive anti-HIV treatment is administered, the death rate can be reduced by 80% and the life expectancy of some patients can be extended by at least 30 years. Without aggressive treatment or lack of treatment, when the disease progresses to the AIDS stage, the average survival period is only 12-18 months, and even shorter for those with severe disease.
The survival of AIDS patients is closely related to their treatment. Early and timely treatment can help delay the progression of the disease and extend the survival period.
