Infection from minimum risk....

I'm wondering if any of the visitors of this board have been infected with HIV after a one time exposure, or while using a condom. Everyone says the chance from a one time encounter is like 1 in 500, and with a condom is basically non existant. If anyone or anyone you know has been infected in such a manner could you please let us know.

What is the meaning of 1/500. Does it mean that you have sex with a HIV + people for 500 times, and then you will one chance to be inflected. It is highly unlikely, everyone know one times is enough to be inflected.

No, that's what everyone assumes. Having unprotected sex with a hiv+ person does not mean that one will be infected. There is a 1 in 500 chance that one can be infected by a one time exposure. It is still a risk but not a certainty.

The 1 in 500 number comes from a one time encounter of unprotected intercourse with an INFECTED partner. Many sources say that it may even be around 1 in 1,000. Now, look at the fact that most people on here were with a partner of unknown status (probably in a low risk group) .... and now we're looking at maybe 1 in 10,000 or something like that. Add to that the fact that many on here are concerned about oral sex - and well, the risk is almost non-existant for many on here.

FallGuy is totally correct. Think of the primary manner in which people catch HIV. Think of a needle with infected blood going into your bloodstream ..... that is an air-tight activity involving blood being "shot" directly into the main bloodstream. Now, think of receptive anal intercourse ..... it's almost an identical situation: Infected semen (sorry to be so graphic) is "shot" into an air-tight mucus membrane that has most likely been torn (and thus bleeding) during the activity. Not only that, but now, this infected semen remains inside this air-tight area, only to be soaked up like sponge. The same concept applies to blood transfusions (but even on a larger scale). These are simply the dynamics of this particular virus .... there are several other viruses that can transmit much easier than HIV, but that is another story all together. So, if you look at a high risk individual - such as someone who shares needles with infected users, or someone who repeatedly is the receptive partner during anal intercourse with an infected partner .... it's easy to understand why this virus has become an epidemic within certain risk groups. The virus does not discriminate .... but the way in which it is transmitted is rather clear and specific. Again, there are unlucky people who do (rarely) become infected after a one-time exposure, but this circumstance would most likely involve quite a bit of blood to blood contact (and some bad luck). Now, I am simply repeating exactly what I was told from a doctor who is an HIV specialist ..... I'm not trying to come off as some expert on the virus; I'm simply passing on facts about HIV. Again, I hope these facts can ease some of the fear out there.

easiest way to explain it is to say that if 500 negative people have sex with a positive person it is likely that 1 of those people would get infected. It can be more or less this is just an average.
