[Mod. LL氏解説:
The endemic area of blastomycosis is less well defined as the other 2 dimorphic fungi [Histoplasma capsulatum and Coccidioides immitis] but, based on sporadic cases or clusters of infection in humans and/or dogs, appears to primarily consist of the Mississippi and Ohio River valleys of the south central and Midwestern USA as well as the area on both sides of the St Lawrence river involving both the USA and Canada. Of note, north central Wisconsin, the location of Marathon County, has been the source of a number of reported clusters of this infection.
