If you live in an area where fungal spores are abundant, you are at a higher risk of contracting the disease. Because fungal spores are abundant in damp forests, if you work as a hunter, forest worker, camper, or farmer, you may be at a higher risk of contracting the disease. Furthermore, the disease is not contagious. Although the most common symptom of the disease is the flu, the symptoms of blastomycosis usually last longer and are more severe than the flu. If the infection spreads through the blood, you may also notice skin or bone lesions.
