100 degree instant inactivation of HIV
The resistance of HIV to the environment is relatively weak, and HIV will basically die soon at 100 ℃ boiling water, perhaps less than a minute.
HIV is a common chemical disinfectant of retroviral RNA, which can easily kill the virus. HIV can also rapidly denature and inactivate proteins under high temperature environment. At 56 ℃ in the environment, HIV is usually inactivated in about 30 minutes, losing its infectivity. So at 100 ℃ in boiling water, the protein and nucleic acid molecules that constitute HIV will rapidly denature, lose their biological vitality, and die in a short time.
AIDS patients need to pay attention not to share personal Household goods with others, such as toothbrushes, and insist on cooperating with doctors to treat, so as to keep the body in a relatively healthy state and avoid related complications. At the same time, we should avoid unclean sexual behavior, prevent AIDS from spreading through sexual channels, and try to avoid injuries. Blood transmission is one of the most important ways of AIDS.
HIV has no cell structure and cannot live independently. It must live in living cells. HIV is a enveloped virus with low resistance to external physical and chemical factors, short survival time and inability to survive on metal surfaces.
Can HIV Survive on Metal Surfaces
HIV has no complete cellular structure. The manifestation of survival is that it can proliferate in living cells. Strictly speaking, HIV cannot survive without living cells. HIV has a capsule. The envelope usually comes from the host cell membrane or nuclear membrane. The envelope contains proteins necessary for virus infection in cells. The envelope is essential to maintain the ability of HIV infection. When HIV is exposed to the external environment alone, dryness, pH and temperature changes will affect the ability of HIV infection.
In a dry environment, HIV usually loses its activity quickly. Completely dry HIV is not infectious. The drying time is related to temperature and humidity. In addition, copper, zinc, silver and other metals can react with proteins to denature proteins and make HIV less infectious. Therefore, when HIV is located on the surface of copper, zinc, silver and other metals, it will become inactive after several decades.
AIDS is usually not transmitted through indirect contact, so there is no need to worry about HIV on metal surfaces. If you suspect that there is AIDS, you can go to the general hospital for examination.
