Stained with blood after a vehicle crash and HIV transmission

Dear Ask The Doctor: Hello about two weeks ago a guy we were riding with crashed. He was fine but there was blood everywhere. Anyways he was getting cleaned up and stuff and the rest of us decided to leave so i move his motorcycle and happened to put my hand in some of his dried up blood(this was after a good 10 minutes)Now is there anyway i could get HIV from this? Thanks

Dear Bryan: The following factors are associated with an increased risk of acquiring HIV infection: Unprotected sex, receptive anal intercourse carries a particularly high risk, injection drug use (sharing needles or drug paraphernalia), occupational needle stick or body fluid splash (estimated transmission rate <0.3%), contaminated blood products (before 1985 in the United States). As you see the risk of transmission in the way that you described is extremely low. The HIV virus needs to be inside the white cells and use their internal structures to replicate and survive. No sooner the body fluid containing the HIV virus starts to dry, 90% to 99% of the virus present becomes disabled upon drying. The HIV virus is very fragile when is outside the human body, like on the floor or on an outer surface and is not likely to survive an important amount of time in outside world. The only studies on the survival of HIV outside the body have been done in the laboratory under controlled scientific conditions. These studies have shown that HIV is not affected by extreme cold, but it is destroyed by temperatures of 60 degrees centigrade and above, detergents or disinfectants (bleach). In HIV contaminated blood when store in blood banks at 4 C , the virus may live no longer than 3 weeks or until the white cells fade away, maybe in frozen state could survive for years. The virus does not spread through casual contact such as preparing food, sharing towels and bedding, or via swimming pools, telephones, or toilet seats. The virus is also unlikely to be spread by contact with saliva, unless it is contaminated with blood.
