Infection rates in the MSM demographic fell swiftly between the mid 80s and the early 90s, the epidemic was under control, then infection rates began to rise and have been rising steadily ever since.

Why did infection rates amongst MSM fall to reasonable levels? Obviously the fear of death from a new disease caused them to self regulate their behaviour. As the condition was gradually thought to be manageable, MSM resumed their original behaviour patterns, with the consequences we now see, 70% of new infections among 0.75% of the population.

The same pattern seems to apply to new Syphilis infections.....where the disease did not originate amongst male homosexuals.
