It also depends on the strain itself- I have the very virulent strain, so even though I'm a non-smoking vegetarian who exercises and eats well, and avoids alcohol generally, and drinks green tea like it's going out of style (plus the socieoeconomic factors I've mentioned) I've still got it. I do agree that high-risk people should be targeted most heavily.

I'm not sure that the anal pap can tell about a genital infection in men- I've read on the CDC website and heard from my two gynocologists that they can't detect it in men without warts.
