Healthcare-Associated Pertussis Outbreak in Arizona: Challenges and Economic Impact, 2011.

An outbreak investigation identified 15 pertussis cases among 5 infants and 10 healthcare professionals at 1 hospital’s neonatal intensive care unit (NICU). The cost of the outbreak to this hospital was $97 745. Heightened awareness of pertussis in NICUs is key to preventing healthcare-associated spread and minimizing outbreak-control-related costs. Bordetella pertussis is a highly communicable bacterial pathogen that causes a prolonged cough illness and is spread by respiratory droplet transmission. Infants aged ≤6 months are most susceptible to B pertussis infection and pertussis-associated complications, including pneumonia, encephalopathy, and death, and are commonly hospitalized for treatment [ 1]. Despite a universal pertussis vaccination program, 27 550 pertussis cases were reported in the United States during 2010 [ 2]. Pertussis outbreaks in healthcare settings can be challenging and costly to control [3]. On September 13, 2011 and September 15, 2011, 3 pertussis cases, including 2 confirmed by B pertussis isolation, among preterm infants discharged ≤30 days previously from a 71-bed NICU of a general hospital (NICU A) were reported by Hospital B, a large pediatric facility, to Maricopa County Department of Public Health. This report describes the outbreak, examines outbreak-associated costs and risk factors that might have contributed to healthcare-associated transmission, and provides guidance to prevent outbreaks in healthcare settings.
