It is not possible to transmit HIV through the act of sharing toilets. HIV is a clinically common sexually transmitted disease caused by HIV infection. The HIV virus is not found in the sweat, saliva, urine or feces of HIV-infected patients or AIDS patients, so HIV transmission does not occur via the toilet. The HIV virus is not active in the body. And if it is a public toilet and the toilet is disinfected regularly, there is no need to worry. This is because ordinary disinfectants can have a relatively good effect on killing HIV.
