Blastomycosis

Blastomycosis is a rare illness caused by a fungus, Blastomyces dermatitidis, which may cause death.  It mainly affects the lungs and less often, the skin.

Blasto sporesThe fungus, B. dermatitidis, that causes Blastomycosis only growns and makes spores under specific conditions of humidity, temperature and nutrients.

The spores get in the air when they are disturbed. People become ill with blastomycosis by breathing in the spores of the fungus.

Blastomycosis is not usually thought to be an illness that you can get from another person or animal.

Can Blastomycosis be Prevented?

At this time, there is no way to know for sure where B. dermatitidis grows in nature.  Because of this, it cannot be controlled with success.
