Can toothbrush infect AIDS?

First of all, about HIV, that is, outside the laboratory environment, the probability of infection caused by isolated blood containing HIV is almost zero. HIV can't live in air, water and food. Outside, these viruses will die quickly, even in blood and other body fluids containing HIV. HIV cannot remain active outside the laboratory environment or in a closed environment (such as syringes and needles).

Secondly, there is almost no virus in saliva, unless the gum bleeds when the person brushes his teeth, and the virus is only brought with the blood.

Finally, if you are really uneasy, you can go to the local CDC to check whether there is AIDS after 4-6 weeks.
