Sorry about the typo Don.
It should have been 15 to 44 of course.

In the West, MSMs may have been the first, but heteros were exposed from the earliest days too, 40 years ago now, via bisexuals, infected blood transfusions and shared needles.
If an epidemic was going to start, it could have done so in everyone of those 40 years.
It just can not spread among heteros as it does among MSMs. Not my opinion but an observation.

There is not really a rise among heteros now. It is just that a community of African people are living here now and it does spread among them.
The numbers are small because there are only a few thousands of them.

Royston was wrong about it, probably knowingly wrong.
He just really wished it was true, and wanted it to be believed.
