Epidemiologic and Laboratory Features of a Large Outbreak of Pertussis-Like Illnesses Associated With Cocirculating Bordetella holmesii and Bordetella pertussis—Ohio, 2010–2011

Abstract

We report the first documented mixed outbreak of B. pertussis and B. holmesii infections. Bordetella holmesii particularly affected adolescents. Although laboratory capacity limitations might inhibit routine use of multitarget PCR for clinical diagnosis, focused testing and enhanced surveillance might improve understanding the burden of B. holmesii infection.
