Public health officials are investigating a blood mystery in the Hometown (Schuylkill, Luzerne, Carbon Counties of PA) area, and they're asking locals for their help.

This week, the Pennsylvania Department of Health and the Atlanta-based U.S. Agency for Toxic Substances and Disease Registry will begin interviewing residents of Schuylkill, Luzerne and Carbon counties who have been diagnosed with polycythemia vera, a rare blood malignancy that a recent PADOH study found to occur locally at an unusually high rate. However, because the agencies face restrictions on calling patients, they're asking the patients to call them.

I've also heard of a possible cluster in Western Kansas.

Anyone else heard of unusual geography or relationship to toxics in play?
