On September 21, 2002, a pertussis case (confirmed by isolation of Bordetella pertussis) was reported to the Yavapai County Health Department (YCHD). The patient was a child aged 13 years in the 8th grade at a middle school in Yavapai County; the child had attended school during the illness. A case consistent with the clinical definition of pertussis had been reported in another student in the same classroom 2 weeks earlier. On September 22, a second culture-confirmed case was reported from the same classroom. Subsequent investigation identified five additional persons (two students in the same classroom, two 8th-grade teachers, and one parent of an ill student) with prolonged cough illnesses. In comparison, during the previous 10 years, an average of four pertussis cases were reported annually from this county. On September 26, YCHD, in conjunction with the Arizona Department of Health Services (ADHS) and school officials, notified the community of the pertussis outbreak in the middle school and initiated control measures. This report summarizes the epidemiology of the outbreak and the control measures used to contain it. Health-care providers should consider pertussis in persons of any age with acute cough illnesses and consider obtaining nasopharyngeal (NP) specimens for B. pertussis culture.
2002年9月21日，亚瓦派县卫生部门（YCHD）接到一起百日咳病例报告（通过分离百日咳博德特氏菌确诊）。患者是亚瓦派县一所中学八年级的一名13岁儿童；该儿童在患病期间一直在上学。两周前，同一间教室的另一名学生报告了一例符合百日咳临床定义的病例。9月22日，同一间教室又报告了一例经培养确诊的病例。随后的调查发现另外五人（同一间教室的两名学生、两名八年级教师和一名患病学生的家长）患有持续性咳嗽疾病。相比之下，在过去10年里，该县每年平均报告4例百日咳病例。9月26日，亚瓦派县卫生部门与亚利桑那州卫生服务部（ADHS）及学校官员联合向社区通报了该中学的百日咳疫情，并启动了防控措施。本报告总结了此次疫情的流行病学情况以及为控制疫情所采取的措施。医疗服务提供者应考虑到任何年龄患有急性咳嗽疾病的人可能感染百日咳，并考虑采集鼻咽（NP）标本进行百日咳博德特氏菌培养。
