Jack, it is an epidemic amongst MSM, not the general population. The condition is actually very rare amongst heterosexuals in "developed countries"

It is almost exclusively a disease of male homosexuality, and that is where the EPIDEMIC occurs.

The confusion arises over percentage rates and real numbers, male homosexuals are only a small demographic, but contain huge rates of infection......the Canadian figures say that around 10/ 15% is the median, that means that between 1 in 10 and 1 in 15, MSM carry the HIV virus. That is an epidemic, which if it pertained to heteros, would be absolutely devastating for society.
