What is the life span of the AIDS virus outside the human body?

I'm a bit confused because some pple say that a few seconds some say it has none then how come a person can contract the virus when sharing needles,razors etc?serious answers please

It is a fragile virus, meaning simple cleaners will kill it...it cannot survive long outside the body (unlike Hep. B which can live on surfaces for up to 2 weeks...get vaccinated).......the issue is that it may live a few minutes, or an hour.....but how can you be sure with each bit of human blood? So the razor, needle risk isn't worth it.

Approximately 60 seconds.Air kills aids.Unless it is a wet surface, then I would recommend bleach.The reason it can be passed via a needle is that once it is in the plunger there is no air.It remains inside the needle with no air therefore it is still a live virus.

Very interested to know too.

The Aids virus is killed within a few minutes after coming into contact with air. A wet surface then a maybe a bit longer.

The dangerous part of any virus is the mutation of it. So far the HIV virus all strains hasn't mutated that much to cause a 'super virus' it is however just a matter of time.

To contract aids from a needle is high as usually these needles are shared between drug users within seconds. A razor blade, the risk is minute. I've never heard of case of Aids being contracted through a razor blade.

The study of bacteria is actually fascinating and getting up close and personal to them is even more so.

May I suggest the book called Life by Lennart Nilsson who has some excellent images of bacteria as well as cancerous cells and the miracle of life. It's a great coffee table book, not much writing but wonderful photography, any one from the medical profession to children would find the photo's fascinating.
