My fellow histonetters,

I would like to inquire about TB exposures.  This would apply to histotechs,
PAs, pathologists, autopsy techs or any other lab personnel working in
anatomic pathology.  Specifically, how many with a prior negative PPD
converted to a positive PPD after exposure to a known case?  Demographics
will factor into this inquiry so if you choose to respond it would be
helpful to know where you're from.  I do not wish to clog the net with
responses, but others on this list may have interest in this data.  
Thanks!
