That information is BS,HIV becomes inactive once outside the body and exposed to air--you had no risk.
Hello, I am from china. I am still a little worried as I have got some datas from china's biggest internet database ------ The Encyclopedia of BaiDu.
These datas are described as follows:
the lifespan of HIV virus in the blood outside the body depends on the quantity of virus. If the quantity is high and the blood id not dry, hiv virus is still active after 96 hours.
The blood with low virus quantity loses vitality after natural drying up after 2 hours. HIV virus in the blood with high virus quantity still can copy once cultured in the culturemedium even 2-4 hours have passed after the blood has was dry.
No risk of HIV transmission from blood stained bed sheets because HIV becomes inactive and unable to infect once outside the body and exposed to air.
