The urine of AIDS patients is not infectious. Generally, urine does not contain the virus, and even if it does, it is very small and not enough to cause infection. Unless the urine of a patient contains a large amount of blood, and the contamination of the urine with blood makes the urine infectious, the urine of a patient will not cause infection. In addition to urine, saliva and feces of patients are generally not infectious. However, the semen, prostate fluid, vaginal secretions, cervical secretions, pleural fluid, ascites, cerebrospinal fluid, breast milk and other body fluids of AIDS patients contain a relatively high level of virus, which can cause infection through contact, so if you want to avoid contracting AIDS, you should avoid contact with the blood and these body fluids of patients.
