Emerging Fungal Infections in the Pacific Northwest: The Unrecognized Burden and Geographic Range of Cryptococcus gattii and Coccidioides immitis.

Both Cryptococcus gattii and Coccidioides can cause debilitating diseases if not identified early. It is imperative that clinicians recognize these diseases and begin treatment quickly when necessary. In order to have these two mycoses in their differential diagnosis, clinicians, microbiologists, and public health officials must be aware of the expanding geographic boundary in the case of Coccidioides immitis and the new emergence in the case of C. gattii. Accordingly, there is now mandatory reporting for cases of C. gattii and C. immitis in both Washington and Oregon, and the Centers for Disease Control and Prevention keeps a repository of available isolates. Through the One Health initiative, clinicians, veterinarians, and public health officials are collaborating to better understand the emergence and expanding geographic range of these extremely important fungal diseases.
