Calculation of odds of getting HIV
Hey people, i found one webpage about the odds of getting HIV from HIV+ partner during unprotected sex.
http://www.poz.com/articles/396_2286.shtml
Is it really so ? Chances are extremely low and it seems like being killed by falling tree is more credible than to get infected with HIV after having straight vaginal sex with the HIV+ girl (odds according to webpage are 1 to 1,000,000).
Ok, data are from 2005, but still... let's assume that after unprotected sex you don't know the partner's HIV status, according to http://www.avert.org/worldstats.htm the average number of HIV infected people in the world is 0.8% (because of high percentage in Africa). Assuming that you have been having unprotected vaginal sex with a girl in North America, your chances of getting HIV from a single exposure are (1/1,000,000*0.5) 0.0000005%. Actually I can't believe it and I think I'm totally wrong.
What are your thougts ?

the information provided on the POZ website is incorrect or information provided and taken out of context by a forum member?
that website is excellent! and by the way although the website has a chart of odds it clearly states that there are so many variables that can affect the odds, anyway I found this on that website:
There are a few basic facts to consider:
Abstinence is the only 100-percent way to avoid HIV and other sexually transmitted infections.
If you have a partner who has tested negative for HIV, does not inject drugs and is having sexual contact only with you, there is minimal risk of being infected with the virus.
Being infected with a sexually transmitted infection (STI) can increase an HIV-positive person's chance of transmitting HIV, just as it can increase an HIV-negative person's chance of acquiring HIV.
An HIV-positive person with a detectable viral load is more infectious-more likely to transmit the virus to somebody else-that an HIV-positive person who is receiving antiretroviral treatment and has an undetectable viral load.
Safer sex practices, including correct and consistent use of condoms for vaginal or anal sex, can reduce the spread of HIV and other STIs.
Getting intoxicated or high on drugs, including alcohol, can impair judgment and cause people to forget to take care of themselves-or their sexual partners.
Safer sex is not just about vaginal, anal or oral intercourse. Masturbation (alone or with someone else), body rubbing, erotic massage and kissing-they're all fun, no-risk activities

I don't understand those odds... according to that having vaginal and anal sex doesn't offer that much more of a risk than oral sex.
So then why do experts and doctors and sites all over the internet consider vaginal and anal sex as high risk activities and oral sex as very low risk?
Ahh confused now!
