一起ECHO 30病毒引发游泳队脑炎爆发调查

Investigation on the outbreak of ECHO 30 viral encephalitis in a swim team

  • 摘要: 目的 分析ECHO 30病毒性脑炎在冬季体校游泳队爆发的特征.方法 应用流行病学描述方法,对体校学生进行筛查;采集典型病例脑脊液(CSF)、血液样本和泳池水样进行实验室检测.结果 病例均为体校游泳队学生,共发病37例,罹患率25.18%,性别间罹息率差异无统计学意义(2=0.03,P>0.50),流行9 d;游泳池水污染严重,6份CSF样本肠道病毒核糖核酸阳性,2份分离到ECHO30肠道病毒.结论 游泳池循环净水和消毒设备应正常运转,日常监督监测应加强.

     

    Abstract: Objective The present investigation was designed to analyze the epidemiological characteristics of the outbreak caused by ECHO 30 in a winter swim team. Methods Descriptive epidemiological approaches were used to screen among the students in the palestra, sampling cerebrospinal fluid (CSF), blood samples and water from the swimming pool for laboratory test. Results A total of 37 cases were involved, all of them being the students of the swim team members in the palestra, the attack rate 25.18% without statistical significance between different sex.(x2=0.03,P0.50). The epidemic process was 9 days. The water from the swimming pool was seriously polluted, while six of the CSF samples were EV-RNA positive, two of which were detected ECHO 30. Conclusion Water purifying and cycling equipments should be running normally. Strict daily supervision and surveillance should be strengthened.
