Blastomycosis Symptoms and Signs
Fortunately, about 50% of all people infected with the fungi do not show any symptoms of blastomycosis. When symptoms of blastomycosis do occur, they appear after a latent or incubation period of time that ranges from about three to 15 weeks after the initial exposure to the fungi. Unfortunately, the initial symptoms of blastomycosis resemble flu symptoms (fever, chills, cough, and discomfort or pain in the muscles, joints, and chest). If blastomycosis is spread by the blood or lymphatic system, skin lesions or bone lesions may develop.
