Blastomycosis in New England: 5 Cases and a Review.

The geographic range of blastomycosis is thought to include New England, but documentation is sparse. We report 5 cases of infection with Blastomyces dermatitidis that were likely acquired in New England between 2011 and 2021. Our experience suggests that chart coding for the diagnosis of blastomycosis is imprecise and that mandatory reporting might help resolve uncertainties about the prevalence and extent of blastomycosis.
