There is no exact value for how many years an AIDS patient can live on free medication because individual health, lifestyle habits and compliance with medication vary, so it is impossible to give an exact value. Usually, people with AIDS who take their medication regularly and on time may live as long as ordinary people. AIDS is an infectious disease characterized by severe immune deficiency that can disrupt the body’s immune function, making it more likely to contract other diseases. Although there is still a lack of specific drugs to cure AIDS, regular medication can minimize viral load, suppress HIV for a long time, keep it at latency level, and allow patients to obtain immune function reconstruction and maintain immune function, and if well controlled, life expectancy may not be affected. According to our policy, medication for AIDS treatment is distributed free of charge, thus patients do not have to worry about the cost of medication. Patients with AIDS are careful not to miss their medication, and not to stop taking it without permission. Patients should try to be in a sterile environment, avoid touching animals and keep warm to reduce the risk of infection. Also reduce the consumption of raw and cold foods to avoid diarrhea, which can lead to other adverse conditions. In addition, patients need to carefully observe their condition and seek immediate medical attention if they develop fever or rapid pulse.
