<div style="font-style:italic;">The CDC has a site that might be of interest to you. It compiles statistics on all reportable diseases: <a href="http://www.cdc.gov/mmwr/summary.html" target="_blank">clicky!</a> This allows you to look at the incidence (number of new cases) of these diseases by year. For example, the incidence rate for diphtheria in 2001 was 2 cases.<br><br>

But in their pink book chapter, they say that toxogenic diphtheria is "still circulating in areas where it was endemic in the past". When they've gone out intentionally culturing to find it, they always do, although it's not doing that weird green membrane thing anymore. (which is puzzling, but bacteria do change over time sometimes). They say it's difficult to culture, and shares "space" with s. pneumo, so it's getting misdiagnosed. It's mostly just causing sinus infections and tonsillitis now, for the most part.<br>
FWIW, it's treatable with antibiotics, just like s.pneumo is, so that's a good thing.
