Pneumonia in Children Caused by Infection of Bordetella pertussis and Two Respiratory Viruses: Case Report and Literature Review

BACKGROUND: "Pertussis reappearance" and its epidemic pattern have changed, and the overall incidence group has shifted from infants and children to adolescents and adults. METHODS: We use real-time PCR technology for nucleic acid detection of multiple pathogens in respiratory specimens. RESULTS: Children infected with pertussis are prone to coinfection with other pathogens. In February and March of this year, ADV and HRV were highly prevalent in the local area. The child visited the hospital multiple times, increasing the possibility of cross infection, resulting in coinfection of pertussis with ADV and HRV. CONCLUSIONS: Early nucleic acid testing for Bordetella pertussis is helpful for the diagnosis of pertussis. Mixed infection pathogens are mainly viral infections. The common mixed infection pathogens in different regions are different and related to the prevalence of local pathogens.
