The number of blastomycosis cases linked to recreation at the Little Wolf River in Waupaca County near New London, WI has increased by two during the past week, bringing the total confirmed cases to 40, with an additional 37 probable cases being investigated.



The Wisconsin Division of Public Health advises the public who have visited the Little Wolf River since Memorial Day weekend of their risk of being exposed to the fungus.

You should see your health care provider if  you develop symptoms including cough, fever, chills, muscle aches, joint pain or chest pain, health officials advise.

Blastomycosis is an uncommon, but potentially serious fungal infection. It primarily affects the lungs, and is caused by the fungus Blastomyces dermatitidis. The signs and symptoms of illness that can result from exposure to this soil organism are variable. Illness may develop 2-15 weeks after exposure to the fungus.

Approximately 50% of people who are infected with B. dermatitidis will not have symptoms. Among the infected persons who develop symptoms, the symptoms vary from mild to severe, and can be fatal. A very serious progressive illness involving multiple organ systems can occur in untreated patient.

    My family and I went to the Wolf river to go tubing July 9th. Out of our group of five, one has a confirmed case of Blasto.
    We live out of state, had it not been for my family and friends telling us to get tested, we would not have known anything about this. The region that I live in has limited resources for treatment. The ONE person in our party with confirmed Blasto is the only case in our state. Please make a better effort to inform travelers about this. Thank you!!
