(Rare Disease of Public Health Significance)
Cause: Fungus Coccidioides.
Illness and treatment: Symptoms can include fever, fatigue, cough, dyspnea, headache, night sweats, myalgias, and rash. Typical presentations are shortness of breath and pneumonia. Disseminated disease may also occur, with bones/joints, soft tissues, and meninges most commonly affected. Infection may be asymptomatic. Treatment is with antifungals.
Sources: Coccidioides sp. are environmental fungi that have been isolated from the soil in south-central Washington; cases are most common in the southwestern United States. Exposure is through inhalation of the organism, generally from dust or disturbed soil.
Prevention: There are no specific precautions.
Recent Washington trends: Since 2010, sixteen human cases of coccidioidomycosis with suspected exposure in Washington have been reported, all from south-central Washington. Animal cases with presumed in-state exposure have also been reported. C. immitis was found in soil from south-central Washington, including in Benton, Yakima, and Kittitas counties.
Purpose of Reporting and Surveillance
- To track the emergence of Coccidioides in Washington.
- To differentiate between infection acquired in Washington versus disease acquired outside of Washington.
- To monitor trends in the epidemiology of disease due to Coccidioides.
