Bordetella pertussis is all over the place. Since the vaccine protects against
disease much better than it protects against infection, groups studying BP
infection can create outbreaks at will. In addition, in the last two years
there have been increases in the US and Canada that may relate to an increase
in adult pertussis (a direct result of adult immunity from previous immunity
vs. previous disease). PCR creates even greater problems since it detects
asymptomatic infections in the contacts of patients with symptoms. We have lot
of BP in NEW YORK. I don't know about the midwest but OHIO had a big outbreak
(see the NEJM article of a few months ago).
