Blastomycosis is a fungal infection that primarily affects the lungs, but can also spread to other parts of the body. It is caused by the fungus Blastomyces dermatitidis and is most commonly found in the central and southeastern United States, as well as parts of Canada. While pulmonary blastomycosis is the most common form of the infection, there are other forms that can occur.
Diagnosis of blastomycosis can be challenging, as the symptoms can mimic other respiratory infections. A definitive diagnosis is typically made through laboratory tests, such as culture or biopsy. Treatment typically involves antifungal medication, such as itraconazole or amphotericin B, and may need to be continued for several months.
Prevention of blastomycosis involves avoiding exposure to the fungus, which is typically found in moist soil and decaying organic matter. People who work or recreate in areas where blastomycosis is common should take precautions, such as wearing protective clothing and avoiding activities that disturb soil or decaying matter. Good hygiene, such as washing hands frequently and covering the mouth and nose when coughing or sneezing, can also help prevent the spread of the infection.
If you suspect you may have blastomycosis or have been exposed to the fungus, it is important to seek medical attention promptly. With early diagnosis and treatment, most people with blastomycosis can make a full recovery.
