Clinical Testing Guidance for Coccidioidomycosis, Histoplasmosis, and Blastomycosis in Patients with Community-Acquired Pneumonia

CDC, Mycoses Study Group, and Coccidioidomycosis Study Group developed this guidance with a multi-disciplinary team of infectious diseases physicians, primary care practitioners, urgent care practitioners, and epidemiologists.

Clinicians in urgent care and outpatient settings can use these algorithms to help make determinations about clinical testing for coccidioidomycosis, histoplasmosis, and blastomycosis in patients with community-acquired pneumonia (CAP). The algorithms address an important gap in guidelines for CAP diagnosis by providing recommendations for primary care, outpatient, and urgent care providers for diagnosing fungal pneumonias. Existing guidelines for CAP diagnosis focus on bacterial and viral CAP.
