In 2007,    The prevalence of HIV (both diagnosed and undiagnosed infections) among MSM aged 15-44 was estimated to be 8.5% (range 7.0-10.5%).

Uh . . . okay, but. . . .

Now, Zippy the Clown might ask at this point, "If a number of men are undiagnosed, how can they be included in any kind of accurate statistics?"

But the, Zippy is only a simple-minded pinhead.
