HIV does not live long outside of the body. Can you please advise me how long?
| Response from Dr. Wohl
HIV does poorly in dry enviornments. So if a drop of blood containing HIV is left out on a surface, the HIV concentration drops as the drop dries and when drying is complete the HIV is essentially zero.
In used syringes, moist areas can persist for days and thus so too can HIV in these areas.
By and large though, no one gets HIV infection from a surface unless that surface is one something getting is stuck into you.
