Two things I hear that really disturb me:
You're only as safe as your last test. No, you're not. The test is meaningless until the HIV seroconversion and that can take as long as 30 days, even six months and, in rare cases, 12 months, but transmission of the disease can occur during that time. So you're only as safe as all the sex you've had in the last twelve months and your partners have had in the last twelve months and their partners have had in the last twelve months. Okay. Use a rubber.
We all take risks every day. Yes, we do. But only a fool plays golf in a thunderstorm or swims in shark infested waters or eats unwashed fruit off a supermarket shelf or walks into a fenced yard with a sign that says "Beware the Pit Bull." We do takes risks when we get out of bed - but we don't take them deliberately and fucking outside a long term committed relationship without a condom is taking a deliberate risk.
I have to admit my point of view is skewered. I know some of the models. I wouldn't want anything to harm them. They're good, nice kids. I can't imagine how horrible it would be to have even one of them become ill because his desperation was taken advantage of and deliberately risky behavior was bought for somebody's viewing pleasure.
The rare cases that have been documented for 6 mos. and beyond are based on not being able to determine the exact date or mode of exposure. It is believed that the inaccuracy of this data is based on the subject not being entirely accurate or truthful with the evaluator about dates and times of engaging in risky behaviors. Rifle, you are so right. in 90 percent of the cases seroconversion takes place with 2-4 weeks. 6 mos. is the recognized maximum window time period by the CDC. However; since we developed the p24 antigen test in 1996 this test can detect before seroconversion. It is about 80% accurate for HIV positive accuracy.
