teak/mikey - I was wondering what your thoughts are on incidence rates of infection. Now I know the virus does not discriminate and anyone can get it but was wondering what the prevalence of it is in the various groups. I guess you can categorize by MSM, IDU, hetero, endemic (any others?) - this is not to say that the infection cant cross into other categories. Say if you live in Chicago - roughly 2.7 million people in the City area (not including the burbs as it gets difficult to slice boundaries). The docs (HHH and hook) frequently mention that the virus is very rare in the general population - but how rare is it? If I were walking in a train station downtown chicago you see people all over the place, business men and women, students, etc.... I sometimes have the thought how many are of those you see are infected. I know its all guesstimates but any general educated breakdown would be interesting.
