Clinician Information As of this posting, case-patients in the cluster reportedly have had fever, di culty breathing, and bilateral lung in ltrates on chest radiograph. For patients with similar respiratory symptoms who recently traveled to Wuhan, consider pneumonia related to the cluster and notify infection control personnel and your local health department immediately.
