As soon as it's exposed to air and ph changes it causes the shell of the virus to rupture ending it's ability to infect.
Thats my last question. I promise
But does it become inactive immediately or there is timelag??????
No, once HIV is inactive you can't make it active again.
Teak, so if semen is ejaculated, the HIV becomes inactive imediately? And if yes, then can it again become active?
It never dies, it's not alive. It's either active or inactive. HIV cannot survive outside it's host.
