Does HIV Aids die when it comes in contact with open air?

The Human Immunodeficiency Virus (HIV) dies in about a minute when outside the body. This is why this disease isn't transmitted by casual contact. It does live in blood that's spilled outside the body, but dies almost immediately when it comes in contact with chlorine {household bleach}.

YES. He's not very resistant outside of the body.

Very quickly. The virus is actually very fragile, which is a good thing. It can't tolerate temperatures outside the range of normal body temperatures ( 95 - 106 degrees F). It can't tolerate dessication (drying), which is why it is fluid borne.
It can't tolerate soap, vinegar, ammonia, alcohol or any other number of household chemicals.

quickly but not immediately, HIV can survive inside the blood until the blood starts to dry up, HIV dries very quickly outside of the body in body fluids, yes HIV is a very fragile virus, that's why it's difficult to infect from one person to another, multiple unprotected exposures are needed to become infected.

if it is a pool of blood or huge blood splatters it canlive longer that is why any time there is a major accident for instance a man with aids shot himself and they went in the house in what looked like hazmat suits to clean it up but if it is just s spot or 2 then chances of you getting it into a small cut and contracting it are very slim
