摘要
2023年10月13日,北京经济技术开发区疾病预防控制中心接到某学校报告,其4年级2班出现多例发热病例,立即开展现场流行病学调查.共报告14例病例,均为学生,罹患率为34.15%.发病时间集中在10月6-15日,主要临床症状为发热、咳嗽和乏力,无住院、重症和死亡病例,检出肺炎支原体P1-Ⅱ型阳性7例.根据现场调查和实验室检测结果判断这是一起由肺炎支原体感染引起的流感样病例暴发疫情.引起疫情扩散的原因可能为病例感染后带病上课通过呼吸道飞沫传播感染同班其他同学.本起疫情仅发生在一个班级,未在邻近班级扩散.提示学校应积极开展健康教育,提高家长传染病报告意识,同时应加强晨午检,提高发现敏感性.
Abstract
On October 13 2023,the Beijing Economic and Technological Development Area Center for Disease Control and Prevention received a report from a school indicating an outbreak of fever among students in Class 2,Grade 4.An on-site epidemiological investigation was immediately conducted.A total of 14 cases were reported,all of whom were students,with an attack rate of 34.15%.The onset of illness was concentrated between October 6 and 15,with the main clinical symptoms being fever,cough and fatigue.There were no cases of hospitalization,severe illness or death.Seven cases tested positive for Mycoplasma pneumoniae P1-Ⅱ.Based on the on-site investigation and laboratory test re-sults,it was an outbreak of influenza-like illness caused by Mycoplasma pneumoniae infection.The likely cause of the spread was cases infecting other classmates through respiratory droplets while attending class.The outbreak occurred on-ly in one class and did not spread to neighboring classes.Schools should actively carry out health education to raise awareness among parents for reporting infectious diseases,and strengthen morning and afternoon screenings to improve the sensitivity of identification.
