Dear Ask The Doctor: Hi, I have a few encounter that I have questionable doubts about, maybe someone can help clarify my risks. Here are my encounters. I received a handjob, during the encounter I was touching the outer part of the womans vagina where I started to feel alittle wetness on my finger tips, after ejaculation, I cleaned the entry of my urethra with the same wet wipe I used to to clean the vaginal fluid off my finger. Is this a possible way of HIV transmission? I also had a few encounters that involved me receiving oral sex with protection, one of encounters involved the woman using excessive saliva. Is this a possible way of HIV transmission? Another encounter involved a woman and I participating in mutual masturbation, no physical contact occured, but during ejaculation, the woman touched the the bottom part of my penis for a split second with the hand she used to masturbate herself. All of my encounter were non penetration encounters. Am I risk of contracting HIV from any of my emcounters?
Dear Angel: 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 on an open wound (estimated transmission rate <0.3%), contaminated blood products (before 1985 in the United States).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 the 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 and this contact an open wound.
