How long? few minutes? few seconds? or immediately? I had read the answer on the website of CDC is :Scientists and medical authorities agree that HIV does not survive well outside the body, making the possibility of environmental transmission remote. and I also read :there are 8 causes "Human Immunodeficiency Virus Transmission in Household Settings — United States.” BUT I can read some answers of export in medhelp are : the virus dies when they are outside the body. I was puzzled, and Which answers are accurate?
