2014－2019年河南省水痘报告病例空间分布特征

Spatiotemporal characteristic of varicella cases reported in Henan, 2014–2019

摘要

摘要:
目的分析2014 — 2019年河南省水痘病例时空分布特征，探讨空间聚集区域，为水痘的防控提供科学数据支持。
方法收集2014 — 2019年中国疾病预防控制中心传染病监测系统河南省的水痘报告病例信息，使用SaTScan、Geoda等软件分析河南省水痘病例的流行病学特征、空间自相关分析和时空聚集分析。
结果 2014 — 2019年河南省通过监测系统共报告水痘病例143 333例，年平均发病率为25.13/10万，发病年龄以青少年为主，全局Moran’s I指数均为正值，分别为0.441、0.392、0.447、0.372、0.335和0.163（P<0.001），高–高聚集区分布在河南省中部地区。
结论河南省水痘疫情呈现上升趋势，以河南省中部地区为主，呈现较明显的时空聚集性。

Abstract:
Objective To analysis the spatiotemporal characteristics of varicella cases reported in Henan province between 2014 and 2019, explore its spatiotemporal clustering areas and provide evidence for the prevention and control of varicella.
Methods The data of all varicella cases reported in Henan between 2014 and 2019 were collected from the China Information System for Disease Control and Prevention for an epidemiologic analysis, spatial autocorrelation analysis and spatiotemporal clustering analysis with software SaTScan and Geoda.
Results There were 143 333 varicella cases reported in Henan province between 2014 and 2019, with an average annual incidence of 25.13 per 100 000. Most cases were adolescents. Global spatial autocorrelation showed that all the values of global Moran’s I were positive, i.e. 0.441, 0.392, 0.447, 0.372, 0.335 and 0.163（P<0.001）. The areas with high-high clustering were detected in central Henan.
Conclusions The incidence of varicella case increased with year in Henan from 2014 to 2019, and the cases mainly occurred in central Henan with obvious spatiotemporal clustering characteristics.
