HIV virus survives outside the body for a few hours to a few days after leaving the body, and usually does not survive under natural conditions.
The HIV virus is very weak and can only survive in blood and some body fluids, and is very poorly adapted to the external environment and will die if left in suitable conditions. If the HIV virus is carried in a small amount of blood, it will also be inactivated within a few minutes outside the body. In the case of HIV carried in larger blood clots, the HIV virus can survive for several hours in a suitable environment before the blood clots.
There is no specific treatment for HIV infection, so prevention is based on cutting off the transmission route, such as not having unsafe sex. HIV is generally not transmitted through daily contact such as shaking hands, hugging, or sharing utensils.
