the reason of inactivation

[wangxian77]

why the HIV virus in blood is so easy to inactivate when the blood leave the body?
why just need seconds for its inactivation even if the blood are not dry?
I want to know the details,thank you very much!!
I was cut on my neck skin when I have haircut,no blood,maybe a little,I do not know because I see the wound 2 days later.I do not know what cut my skin,maybe razor,maybe hair Clipper,I am sure that no one has used the razor and the hair Clipper only for 3-4 minutes,I do not know whether there is blood on these tools,my  wound

This is an HIV prevention forum where people can get risk assessments, not a place for biology lessons.  You can google the information you seek...there have been numerous studies where the biology and life cycle of the HIV virus have been closely studied.  Without an education in biology or medicine, it will be difficult for you to understand the information.

Unless ypi have a bacground in biology, it's not something you wouljd understand.  The details are unimportant....just accept the fact that HIV is a very weak virus.

why the HIV virus in blood is so easy to inactivate when the blood leave the body? protein denaturation?
