1. How long can HIV survive
It is a very fragile virus. This virus cannot survive on its own. It must be a parasite to survive. For example, a single virus will die in a few minutes in human blood. If it is a simple virus, it will not cause transmission. of. Viruses need to rely on human genetic genes to replicate and survive in white blood cells. While white blood cells are alive, cells carrying the virus can spread AIDS. When the cells die, the virus dies. Viruses that are free outside cells will die quickly, and will also be degraded quickly whether they are in the human body.
2. How long does the blood of AIDS patients survive in the air
AIDS is transmitted through blood or body fluids. Although HIV is highly contagious, it is also very fragile. Because they can only survive in living cells in blood and body fluids, they cannot survive in air, water or food. When HIV leaves these blood and body fluids, it quickly dies. Therefore, HIV generally only survives for a few minutes when exposed to the air.
3. How long can HIV survive when blood is invisible to the naked eye
AIDSThe amount of viral infection is required, and in the case you\’re talking about you generally don\’t get HIV in the blood that is invisible to the naked eye, and it doesn\’t survive for more than a few minutes. It does not survive dry conditions for more than a few minutes and is not immediately deactivated. When blood dries on a person\’s hands, the blood becomes inactive and HIV cannot survive when it comes into contact with paper.
4. How long does HIV survive outside the body
The survival time after human infection is related to the specific environment in which the virus is located. If the HIV virus is completely exposed to outside air, the HIV virus dies rapidly within minutes. If the HIV virus remains in the blood after leaving the body, it may remain viable for several days unless the blood dries up.
5. How long can HIV survive in pure water? 30 minutes
HIV can survive in liquid environments at room temperature for 15 days, and HIV-contaminated items will be infectious for at least 3 days. In recent years, some research institutions have proven that the survival time of HIV virus in isolated blood is determined by the virus content in the isolated blood. Blood with high virus content, if it is not dry, still has the potential to survive even if it is left at room temperature for 96 hours. vitality. Even in a drop of blood the size of a pinhead, if it encounters fresh lymphocytes, HIV can continue to replicate in it and can still be transmitted. Blood with low virus content will lose its vitality after natural drying for 2 hours; while blood with high virus content, even if it dries for 2-4 hours, can still enter the culture medium and encounter lymphocytes and continue to replicate. . Therefore, isolated blood containing HIV can cause infection.
But HIV is very fragile, and HIV in liquid can be inactivated by heating it to 56 degrees in 10 minutes. If boiled, it can be quickly inactivated; at 37 degrees, use 70% alcohol, 10% bleaching powder, 2% glutaraldehyde, 4% formalin, 35% isopropyl alcohol, 0.5% Lysol and 0.3% ethanol. Treatment with disinfectants such as hydrogen oxide for 10 minutes can inactivate HIV. HIV can be transmitted through subcutaneous needle puncture. HIV is not transmitted through droplets from coughing and sneezing.
6. When AIDS blood is exposed to the air, how long does it take for the virus in it to lose its life
HIV itself may live longer. Generally speaking, HIV has two concepts, one is the survival time of the virus, and the other is the infection time. What\’s really worryingIt could be infection time. If we consider the survival time of AIDS, it may be several hours or even weeks. Only under low temperature or even freezing conditions, the virus may survive for weeks or even longer, but in a natural environment, it is generally within 4-5 hours. AIDS will be completely inactive. Usually blood is no longer contagious after leaving the body for a few minutes, so there is no need to worry.
