In general, if you get HIV on your hands, the HIV virus usually only survives for about 2 hours. As long as you keep your skin intact, you will not be infected with HIV. HIV is spherical in shape, the genetic material is single-stranded RNA, the outer layer is a protein coat, and the outermost layer is an envelope composed of proteins, lipids, and sugars. The virus is transmitted mainly through sexual transmission, blood transmission, and mother-to-child transmission. HIV can only be parasitized in the blood of the human body, the ability to adapt to the outside world is extremely poor, leaving the human body will soon die. HIV is sensitive to temperature and can die in 30 minutes at 56°C. The higher the temperature, the shorter the survival time. HIV on the hands may survive for up to 2 hours. As long as the skin is kept intact, it is unlikely to be infected with AIDS. If you may have HIV on your hands, you should check your skin immediately to see if there are any breaks in the skin. If there are no breaks, you can disinfect the skin with disinfectants such as sodium hypochlorite and 50% ethanol, and if there are any breaks, you should go to the hospital immediately for treatment.
