I can't speak to the number of infections coming from heterosexual sex as a result of the partner being infected with HIV, but we definitely know that happens. I would challenge folks to look at the stats. If you look at a city like Vancouver, you see that 60% of new infections are gay men; but then when you look at smaller Prince George, you see that only 2% are gay men, because there's this large heterosexual category that doesn't exist anywhere else.
Is it possible that these people are just not out, so they're not being recorded as having MSM infections? We know that's the case because we have data that says that up to 60% of guys are not out to their health care provider. If you're not out to your doctor, why are you going to tell this public health nurse who just told you you have HIV?
