Shared use of razors carries the risk of HIV infection. If the razor cuts the skin and bleeds in the process of shaving, and it happens that the person has AIDS, then he or she will come into contact with the blood of the AIDS patient, and if the razor is not sterilized in a special way after use, then if it cuts the skin and bleeds in the process of shaving another person, it is possible that the razor will become infected. Of course, if the skin is not cut in the process of shaving, even though the person is suffering from AIDS, he will not be infected with AIDS when shaving other people.
