And, for clarity, I haven't concerned my self with statistics for "MSM" which I hadn't even heard of 'til last week. What I said the first time I mentioned figures was simply: And we have now had HIV/Aids with us for well over 30 years that we know of, yet the number of HIV-positive people in the UK is under 100,000, fewer than one in 600 of the population (and by no means all will develop Aids).
