How long can AIDS live?

The natural history of AIDS is clinically divided into acute infection period, asymptomatic period and AIDS period.

Acute infection usually occurs about 1 ~ 2 weeks after exposure to HIV, and acute symptoms last about 2 ~ 4 weeks. After acute AIDS infection, most patients have a long asymptomatic period, but the length of each individual varies greatly. The asymptomatic period from infection with AIDS-1 to clinical symptoms or further development of AIDS is about 8 ~ 10 years. About 5% of AIDS-1 infected people have no clinical symptoms and can maintain a normal immune state of 65438+. The average survival time of untreated people after entering the AIDS phase is 12 ~ 18 months. The above is the survival time without any treatment after getting AIDS.

At present, the biggest problem in the diagnosis and treatment of AIDS in China is that HIV-infected people are not found early, so that these "invisible" infected people are diagnosed when they enter the late stage of AIDS. At this time, the number of CD4+T lymphocytes in their bodies has dropped to dozens or even several per microliter of blood (the normal value is 750 250/microliter), and the human immune function has almost disappeared, so most of them have serious opportunistic infections and tumors.

Experts say that at present, the most effective way to control the source of infection is to treat the infected person without vaccine, and the life span of patients who start antiviral treatment ("cocktail" therapy) in time can be extended by more than 30 years.

If infected people can be found early and active treatment measures are taken, it is not a dream to extend their survival time for more than 30 years.
