Dear experts, I am an Asian, so English is not very good. I would like to ask the forum to point out that HIV is immediately inactivated in the air, but if there is a large amount of blood and body fluids in the air, these HIV exist in these blood and body fluids, and these blood and body fluids are fresh, so it will not give HIV a living environment ? Is HIV not contagious when exposed to the air? Is there no danger of the wound coming into contact with such a liquid?
