In vitro survival time of AIDS virus
Depending on the specific environmental conditions, the survival time of HIV in vitro may vary greatly. If it is in a dry environment, HIV usually quickly denatures its protein, loses its activity and can only survive for a few minutes.
According to the temperature and environment, the survival time of HIV in vitro has a great relationship. It is generally believed that HIV is sensitive to low heat and has strong tolerance to low temperature. High temperature is usually around 56 ℃. AIDS virus can treat human T lymphocytes in vitro for minutes, but it cannot completely inactivate HIV in the blood. HIV can be completely inactivated within 20 minutes at 100 ℃, so HIV must survive in vitro for more than 30 minutes at room temperature. Generally speaking, AIDS has no clear route of transmission, mainly through sexual behavior, blood and blood products, as well as mother to child transmission. General daily contacts, including handshakes, hugs, ritual kisses and shared meals, are generally not infected with HIV.
If HIV is in a humid environment, if there is no dry blood, it can survive for a long time, hours or even days. Research shows that HIV can survive for more than 96 hours because local blood is not easy to dry and coagulate.
In addition, the environmental temperature also has a great impact on the survival time of HIV. For example, at 56 ℃, 30 HIV can be inactivated within a few minutes. The higher the temperature, the faster the HIV death rate. Under appropriate laboratory conditions, HIV can survive for up to 15 days. The best way to kill the HIV virus is to boil it or sterilize it with high-pressure steam.
How long can the HIV virus survive without the human body
Survive for about 10 days in a greenhouse environment and for about 30 minutes at high temperatures. Generally speaking, after HIV leaves the human body, its in vitro viability is relatively poor, and it is not heat-resistant. If you are exposed to HIV in your daily life, you may not be infected. In general, HIV infection rates are high, transmitted through blood, sexual transmission and mother to child transmission. Usually, we must do our own prevention work well and not confuse sexual behavior. We need to wear condoms during sex. This can reduce sexual organ contact and reduce the HIV infection rate.
