MMWR Morb Mortal Wkly Rep

On September 5, 2014, the public health department of a Maryland hospital was notified of a case of Bordetella pertussis infection confirmed by polymerase chain reaction (PCR) in a staff health care worker (HCW). The HCW experienced onset of diarrhea and malaise (nonrespiratory symptoms atypical of the catarrhal phase of pertussis) on August 26. By September 2, paroxysms of coughing led the HCW to consult a colleague, who ordered the PCR test, prescribed a 5-day course of azithromycin, and advised avoidance of patient care until treatment completion. Contrary to the hospital's infection control policy, neither the HCW nor the colleague reported the presumptive diagnosis of pertussis to the hospital's public health department. The HCW continued to work in the outpatient department until the positive PCR result was received on September 5, at which time the hospital's public health department was first notified. The hospital barred the HCW from further work at the hospital while ill, and, in collaboration with local and state public health counterparts, began a contact investigation and stratified patient and HCW contacts by level of exposure.
