This is from the category ... Legends. Somehow information was wandering around the network, they say, HIV-infected people infect healthy citizens in public transport. They say they insert needles with a drop of contaminated blood, a person sits on a chair, pricks himself on the needle - HIV begins to hurt. Film This is actually impossible. First, the virus lives in an open environment for a very short time. Secondly, this amount of blood is not enough to infect a person.
It's the same story with insects. Otherwise we would all be sick
Because HIV in the blood of a person who has left this person does not live long, it is generally a rather unstable virus. And blood-sucking insects do not immediately devour the second person after being sucked from the first, but digest it.
