If you have visited the Little Wolf River since Memorial Day weekend (May 23-25, 2015), you may have been exposed to the fungus that causes blastomycosis. If you develop symptoms including cough, fever, chills, muscle aches, joint pain or chest pain, visit your health care provider.

Blastomycosis is caused by the dimorphic fungi, Blastomyces dermatitidis. It is endemic in the southeastern and Midwestern United States and his classically associated with the Ohio and Mississippi river valley region.

People typically get infected with this fungus via the lungs through inhalation. Infection can mimic bacterial pneumonia and chronic infection is often confused with tuberculosis.

The fungus can also disseminate through the bloodstream infecting the skin causing lesions on the face and extremities. To a lesser extent, the bone, the prostate and the epididymis can become infected.

Untreated disseminated or chronic pulmonary disease can progress to death.

Blastomycosis can be diagnosed through laboratory testing to include microscopic exam, culture and molecular methods. Itraconazole is the drug of choice for treatment of blastomycosis.

    I got Blasto, you don’t want it. If you are short of breathe, get your ass to the doctor. There were a few nights I was afraid to go to sleep in fear of not waking up. This is nothing to mess around with. Mine started off like the flu with aches, weak as hell, sweats, uncontrollable shakes. then went for 2.5 days then my chest tightened up and could only take half breathes. This is the point where it got scary….get to a doctor and get it looked at before you get to this point. A few nights I slept all of 2 hours because I was afraid I wouldn’t wake up
