Anonymous users2024-01-24At room temperature, HIV can survive for 15 days in a liquid environment, and HIV-contaminated items are contagious for at least 3 days. In recent years, several research institutes have demonstrated that the survival time of HIV virus in isolated blood is determined by the amount of virus in isolated blood, and blood with high viral content remains viable even if it is left at room temperature for 96 hours when it is not dried. Even a drop of blood the size of a pinpoint can be transmitted if it encounters fresh lymphocytes, in which HIV can replicate and spread.
Blood with low levels of virus loses its vitality after 2 hours of natural drying; And the blood with a high content of the virus, even if it dries up for 2-4 hours, once it is put into the culture medium and encounters lymphocytes, it can still enter it and continue replication. Thus, isolated blood containing HIV can cause infection.
But as long as you don't touch the wound, you won't get infected!
AIDS is transmitted only through mother-to-child [breast milk], sex, and blood.

Generally not, but in public places, it is necessary to pay more attention to health and safety, etc., and the five necessary factors of HIV infection are indispensable: 1. The other party has the virus, 2. The virus has a huge load, 3. The wound has oneself, 4. The wound and the virus body fluids have been in contact with each other repeatedly, and 5. The virus stays on the wound for a long time. Effective prevention can avoid infection, and the saliva collector Tmall samples are collected at home and mailed to the testing center, and the test results are more reliable.
Unless the previous user touches the doorknob with an HIV-infected person and gets their own fresh bodily fluids (saliva, blood, etc.) on them, and the latter user touches the bodily fluids of the previous one with a bleeding wound in 3 seconds - I don't believe there is such a coincidence, such a bad thing in the world! >>>More
No, the survival of the virus has high requirements for the environment, even if there is a virus, it dies in the water for a while, so don't worry too much
I hope that I will be better, and I hope that the people around me will be better. Please, the virus will only appear in your home if the people around you are infected. >>>More
