how long does HIV survive in air?

Hello and welcome to e health forum.

For your information HIV cultures in accredited research laboratories is done under strict conditions, as it is not able to survive outside the host cell.

HIV is a very delicate virus and its survival outside the host cell requires multiple factors including specific Ph, temperature, moisture, etc.

In the absence of the required factors HIV outside the host cell can lose its infectiousness within a few minutes to a few hours (depending on the specific surroundings). The location or the country does not matter much.

When infected blood, comes into contact with intact skin, it does not result in infection. This is due to the fact that HIV cannot penetrate the thick keratin layer on the skin.

But, HIV can be transmitted when infected blood comes into contact with open wounds, open sores and deep cuts on the body. Viruses in the infected blood can infect the living tissue within such surfaces and hence result in infection. But for this to happen the blood should be in sufficient amounts, should be fresh and the skin cuts or wounds should not have healed.

I hope this helps.
