AIDS is generally not transmitted through saliva, sweat, urine and other bodily fluids, so if you just touch the bodily fluids of a person with AIDS before washing your hands, don’t worry, even if you don’t wash your hands, it is unlikely to cause transmission. If you come into contact with bodily fluids containing high levels of HIV, such as blood, before washing your hands, you may be infected if you do not wash your hands and come into contact with your own mucous membranes or wounds, so you should wash your hands in this case. Hand washing only needs to pay attention to the visible bodily fluids after washing off, can completely ensure that will not be infected. And don’t worry too much about whether all the HIV is washed off your hands, because it’s not likely to cause infection.
