AIDS can be transmitted through body fluids because the body fluids of AIDS patients also contain a relatively high level of the virus. So when a healthy person’s wound comes into contact with the patient’s body fluids, the virus in the body fluids can enter the body through the wound, thus causing infection in the healthy person, and these body fluids mainly include semen, prostate fluid, vaginal secretions, cervical secretions, pleural fluid, ascites, cerebrospinal fluid, and breast milk. The feces, urine and saliva of AIDS patients usually do not contain the virus and are not infectious. To avoid contracting AIDS, you should try to avoid letting your wounds come into contact with the patient’s blood and body fluids. This is especially true for family members who take care of AIDS patients.
