The Latest Rates for HIV

The CDC reports that the overall occurence of HIV in the US is about one-half of one percent, depending on risk group, of course.  Combine these numbers with the published sensitivity and specificity of the fast HIV test, and you’ve got a great lecture on Bayes’ Theorem.

Tip from the Drudge Report.

Update (30 January).  Changed the FDA link for sensitivity and specificity, since the old link reported specificity as 100%, which is ludicrous.
