Disease Reporting


Blastomycosis is an uncommon, but potentially serious fungal infection. It primarily affects the lungs and skin and is caused by the fungus Blastomyces dermatitidis. The illness that can result from exposure to this organism is extremely variable. Infected individuals may not develop any symptoms or may develop mild and rapidly improving respiratory symptoms; a very serious progressive illness involving multiple organ systems can occur in untreated patients.
