2018-2020年浙江省杭州市学生因流感样症状缺勤监测结果分析

Surveillance for school absence due to influenza like illness in children in Hangzhou, Zhejiang, 2018–2020

  • 摘要:
      目的  了解杭州市幼托儿童和中小学生因流感样症状缺勤状况,分析学校因流感样症状缺勤数、哨点医院流感样病例(ILI)数、同期幼托儿童和中小学生流感报告病例数之间的关系,为学校流感样疫情的预警预测提供参考依据。
      方法  收集2018年9月至2020年1月共3个学期杭州市幼托儿童及中小学生因病缺勤、因流感样症状缺勤数据。 采用Spearman法分析缺勤与哨点医院监测ILI数、网络直报流感病例数的相关性。
      结果  全市共监测到因流感样症状缺勤人天数合计158 171人天,缺勤率为0.11%,不同学龄学生缺勤率差异有统计学意义。 哨点医院5~14岁年龄组ILI发病数与学校因流感样症状缺勤数相关性较高(r=0.558,P<0.001)。 学生及幼托儿童的流感报告病例数与学校因流感样症状缺勤数相关性良好,在“提前1周”相关系数最高(r=0.754,P<0.001)。
      结论  幼托儿童和小学生是流感样症状的高发群体;学校症状监测系统可反映流感在学校的流行状况,可在学校流感样疫情的早期预警和预测中发挥积极作用。

     

    Abstract:
      Objective  To evaluate the school absence due to influenza like illness (ILI) in children in kindergartens and schools in Hangzhou, analyze the correlation among the number of school absence due to ILI, the number of ILI cases in sentinel surveillance and the number of influenza cases reported in children during same period, and provide evidence for the early warning of influenza epidemic in schools.
      Methods  School absence surveillance data in kindergartens, primary and middle schools in Hangzhou from September 2018 to January 2020 (3 semesters) were used to analyze its correlation with sentinel surveillance data of ILI and reported incidence data of influenza in children with Spearman method.
      Results  The overall school absence due to ILI was 158 171 person-days in Hangzhou, the absence rate was 0.11%. The differences in absence rate among kindergartens, primary schools and middle schools were significant. The sentinel surveillance data of ILI were highly correlated with school absence surveillance data due to ILI in age group 5–14 years, (r=0.558, P<0.001). The number of influenza cases in young children and students was highly correlated with the number of school absence due to ILI, the correlation coefficient was highest at one week ahead (r=0.754, P<0.001).
      Conclusion  Children in kindergartens and primary schools are at high risk of ILI. School-based ILI surveillance plays an active role in influenza surveillance in kindergartens and schools.
