Wikipedia gives estimates on differences between anal and vaginal transmission are about 8-1 but also admits the numbers could be off by a factor of 10.
What we know is that the AIDS epidemic was at it's worst in Africa where it was largely spread through heterosexual transmission.

I was going by Health Canada numbers -- either way, there's a difference.

Agreed.

It is spread by widespread heterosexual sodomy in Africa in addition to homosexual sodomy.
It's clear that HIV can spread via a wide range of sexual activities, but some are much higher risk than others. At the extremes, receptive anal intercourse has a transmission risk roughly 50 times higher than insertive vaginal intercourse, while the risk of oral sex is believed to be non-zero but too low to be accurately measurable.
