How long does HIV virus live after its left the body?

u cant catch it from touching something someone else has touched can u?

You can't catch HIV through any means other than sharing bodily fluids, i.e. sex or contamination through blood by open wound or infusion.

So if someone with HIV coughs on you, you're fine. If they throw up on you at a party, you're fine. You can share drinks, take a drag off their cigarette, etc. You can use the same doorknobs, pencils, keyboards, tennis rackets, etc.

I have no idea how long the virus lives once expelled from the body, but I do know that HIV can stay live in donated blood for some period of time. Samples of dried fluids, like blood, should kill the virus as it doesn't survive well in dry environments, but precaution is always best.

Once outside the body, exposed to air, HIV only lives for a few minutes at MOST. You can't get HIV from touching something someone else has touched. It is not spread by saliva or by casual contact.

HIV CAN be spread by having unprotected sex with someone who is infected, sharing needles for drug use with someone who is infected, or transmission from mother to child during birth or breastfeeding.

HIV lives for a long time outside the body, the person saying a few minutes at most is spreading misinformation. However its still unlikely to contract HIV in this manner due to the fact that someones blood or other bodily fluid would have to come in contact with a open sore.

12 hrs.. you can catch hiv, if you come in contact with body fluids of theirs, if you have a cut on you.. just becareful...
