What are the probabilities of a person catching HIV/AIDS, statistically

What are the probabilities of a person catching HIV/AIDS, statistically?
I mean like, 1 in 10,000 or 1 in 25,000? The web has too many generic figures! Post your info please.

I don hav figures but I no that infectivity with HIV is very low. It's only lack of sure cure that people r so much afraid of it.

According to estimates from the UNAIDS/WHO AIDS Epidemic Update (November 2006), around 37.2 million adults and 2.3 million children were living with HIV at the end of 2006. http://www.avert.org/worlstatinfo.htm That's 39.5 million people total who are HIV+. There are about 6.1 billion people on the planet. (39.5*10^6) / (6.1*10^9) = 6.475*10^-3 that's a worldwide prevalence of 6.475 people per thousand or about 0.65 percent of the population. So what are the chances off a person being HIV+ it's a little more than half a percent. HOWEVER That assumes all people are equally at risk of contracting HIV. While all people are at risk of contracting HIV, some people are MORE at risk than others. For example, a monogamous lesbian who does not use any injectable drugs and has never had a blood transfusion nor accepted any donor sperm is far LESS likely to get HIV than a male steroid-injecting bodybuilder who receives anal penetration from multiple anonymous male partners who don't use condoms. Some activities are riskier than others. To quantify risk would involve a whole lot of multivariate analyses. You could try to read a lot of journal publications on the matter, but that's a lot of work. So is there a raw number that I could give you? Not without a whole lotta work involved.

If your a non-drug user that doesn't engage in sex or have surgery then your odds are pretty much zero. If on the other hand your a crack head that shoot up with any needle you find and engage in unprotected sex in exchange for drugs and live in Southern Africa - I would say closer to 90% chance you'll be infected within 5 years. Your question isn't really of any value to you. Everyones probability of getting aids/hiv varies based on their lifestyle. A blanket number for all of humanity would over estimate the probability of some people and under estimate the probability for others. So if you want a meaning full answer you should provide some relevant details about yourself... Are you Male or Female... Females are more likely than males to get it if both are hetrosexual. If your male are you gay or straight. Are you married or in a long-term committed relationship do you practice any type of safe sex like condoms do you use drugs do you have any type of medical condition that requires blood transfusions. What country do you live in Those are just a few of the questions you have to have answer to before you could even begin to give someone the odds they would get aids/hiv.

The probability depends on whether you engage in activities that might expose you to HIV. That's why there are so many different figures. If you are not sexually active, do not inject yourself with needles, do not suffer a needlestick, and are not otherwise exposed to body fluids, the probability is close to 0%!
