The Spread of HIV

Chart from TDAXP

According to a study in the Journal of the American Medical Association, men almost never get HIV from women. A healthy man who has unprotected sex with a non drug-using woman has a one in 5 million chance of getting HIV. If he wears a condom, the odds drop to one in 50 million. And though it's easier for men to infect women, the odds that an HIV-positive man will transmit the virus to a woman through sex are less than one in 1,000.
