Sweat does not transmit AIDS because it does not carry the AIDS virus, or even if it does, it is very small and does not constitute an infection. In fact, in addition to sweat, saliva, urine and feces do not cause HIV transmission. The main cause of HIV transmission is the blood, semen, prostate fluid, vaginal secretions, cerebrospinal fluid, pleural fluid, ascites, etc. of HIV patients, which contain more HIV. Therefore, to avoid the transmission of AIDS, you should pay attention to avoid contact with the blood of AIDS patients and the above-mentioned body fluids. If the skin comes into contact with it, there is no need to worry too much, because intact skin mucous membrane can prevent the human body from being infected with AIDS, and the skin mucous membrane can be rinsed and disinfected with running water immediately after contact.
