The saliva of an AIDS patient does not transmit AIDS. The saliva of an AIDS patient usually does not contain HIV. Even if saliva contains HIV, it is very small, and this is not enough to cause HIV infection, so saliva of AIDS patients will not transmit AIDS, and ritual kissing with AIDS patients will not transmit AIDS. In fact, the relatively high viral load in the body of an AIDS patient is mainly due to the blood of the AIDS patient and some body fluids, such as the semen and prostate fluid of a male AIDS patient, which are relatively high in viruses. The vaginal secretions and cervical secretions of female AIDS patients also have a relatively high viral load, as well as cerebrospinal fluid, pleural fluid and ascites also contain relatively high viral load. Therefore, if you are with an AIDS patient, you should try to avoid contact with the blood and body fluids of the AIDS patient so that you can avoid contracting AIDS.
