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 ?

Spot on but how can you know someones status at the time of exposure as there is a window period
BOTTOM LINE IS THAT IF YOU HAVE UNPROTECTED VAGINAL / ANAL INTERCOURSE WITH SOMEONE WHOSE STATUS YOU DO NOT KNOW...THEN YOU RUN A RISK OF CONTRACTING NOT ONLY HIV, BUT OTHER STDS AS WELL.
A RISK IS A RISK ! !
A RISK IS A RISK ! !
When a condom is used correctly and consistently they are 100% effective in preventing the transmission of HIV and most STDs.
well 1 in 1000000 is completely ******** it cant be that high it must be around 1 in 3000 or maybe a little more and the odds in this article about receptive oral is really ridiculous and funny.
The information about safe sex on poz.com is completely accurate. abstinence is 100 percent and then i think protected oral would be around 100 percent too but protected penetrative sex in the long term is not 100 percent safe, practically as there are chances of condom failures and in the long run in real world most people dont use them consistently. I guess protected sex for one time exposure where the condom remained intact and in place is very safe indeed next to zero.
