There's a kind of energy to publish things based on individual interviews and what we call "publication bias" towards potentially sensational articles as Rick and as Kim pointed out. That six-month window is probably much longer than actually would occur, but we took a wide period of time in order to rule out any other possible exposures. Some would say yes, some would say no. I think it's appropriate that we refer to receptive sex on a male partner as "fellatio," since that is an appropriate and well described term for the act. Unprotected sex refers to sexual contact that does not involve the use of condoms or biomedical prevention i. Are bitten by a mosquito or any other bug or animal. One of these other fluids must be present, and there must be a way for them to enter the HIV-negative person's bloodstream such as mouth sores or genital ulcers , for HIV transmission to be possible. At least, I think from everyone I'm hearing except Jeff. Your viral load is currently very low, which make any risk incredibly low. And so we have to continue to promote responsible sexual behaviors, using condoms and reducing exposure to infected semen, no matter what practice they're having. We had about a hundred seroconverters who were prospectively identified and were asked about their risk behaviors both prospectively--before their infection status was known--as well as retrospectively, when they were queried in great detail about all of their potential HIV exposures from three months prior to their last negative HIV test all the way through their first positive HIV test. We did a first step, which was to look at a baseline questionnaire that they did when they were enrolled that included a series of questions about how they might have been exposed to HIV. Touch, hug or kiss a person who is HIV positive. Doctors and researchers can't be sure how many people have acquired HIV through oral sex. If you're able to do that, that's the safest thing you can do. There was another person who reported only oral sex and no other exposures, and when I'm saying no other exposures, we're just taking a very broad period of time-a six- month period, up until the day they went for the first positive HIV test, or symptoms of potential acute HIV infection.
