HIV is not generally contagious when it comes to water. HIV is mainly found in the blood, semen, vaginal secretions, breast milk, cerebrospinal fluid, and chest and abdominal fluids of patients with HIV. HIV is rarely found in the saliva or sweat of HIV patients. The HIV virus is not capable of infecting people once it is out of the body, in the air or in the normal daily environment. Clinically, it has been found that swimming in the same pool with HIV patients does not cause HIV infection, so there is no need to be afraid of getting infected by going to public baths. However, it should be noted that there are some diseases that can be transmitted through towels and washcloths contaminated with STDs, such as syphilis, genital herpes, and condyloma acuminata.
