AIDS is actually an abbreviated model of AIDS, and the transmission of this disease is mainly through sexual contact, as this disease is actually a sexually transmitted disease. Usually, it is transmitted in three ways, besides sexual contact transmission, it can also be transmitted vertically from mother to child and also through bloodstream transmission. Therefore, in the prevention and treatment of AIDS, it is usually done mainly through these three ways. For indirect transmission, we need to pay attention to local isolation, especially the contaminated objects used by patients need to be isolated separately to avoid other healthy people from getting contaminated or being contaminated. In particular, the broken wounds of healthy people should try to avoid the patient’s secretions, including blood or some other secretions, etc.
