Abstract
in English, Chinese

Objective: To explore the characteristics regarding temporal, spatial and spatiotemporal distribution on severe fever with thrombocytopenia syndrome (SFTS) in Henan province. Methods: Surveillance data related to SFTS was collected in Henan province, from year 2014 to 2016. Descriptive method was used to analyze the distribution of SFTS. 1.7.0 software related to the Public health geographic information system (PHGIS), was applied to draw the spatial distribution map of SFTS. Chi-square test was used to compare the different incidence rates. Results: A total of 2 781 SFTS cases, including 34 deaths, were reported in Henan province from 2014 to 2016, with an average annual fatality rate as 1.22%. There were statistically significant differences for the incidence rates of SFTS between different years (P<0.01). Cases were mainly concentrated from April to October, which accounted for 96.66% of the total number, with the incidence peak seen in May. Incidence rates of SFTS in spring, summer, autumn were higher than that in winter. The cases were scattering around in 26 counties of 8 cities. Xinyang city reported 2 714 cases, accounting for 97.59% of the total number of cases in the province. The average annual incidence rate in Xinyang city was 17.22 per 100 000, much higher than that for the whole Henan province (0.98 per 100 000), with statistically significant difference (P<0.01). Six counties reported having death cases, that accounted for 23.08% of the total number of counties, reported to have death cases. Two kinds of incidence patterns of SFTS were noticed in Henan province, with aggregation in some local regions or sporadic in individual counties. The number of counties with reporting cases increased annually. The epidemic area was expanding and gradually spreading from south to north areas of the province. Conclusions: SFTS was characterized with both temporal and spatial clusters in Henan province. Effective prevention and control measures should be made in accordance with the spatiotemporal distribution and the trend on SFTS.

目的： 探讨河南省发热伴血小板减少综合征（SFTS）的时空动态分布特征。 方法： 收集2014－2016年河南省SFTS疫情监测资料，应用描述流行病学方法分析SFTS病例分布特征，采用公共卫生地理信息系统（PHGIS）1.7.0软件绘制SFTS空间分布图。率的比较采用χ(2)检验。 结果： 2014－2016年河南省共报告SFTS病例2 781例，死亡34例，平均病死率为1.22%。不同年份发病率的差异有统计学意义（P<0.01）。SFTS病例主要集中在4－10月，占病例总数的96.66%，5月为发病高峰。春、夏、秋季发病多于冬季。病例分布在8个地市26个县（区）。病例主要集中在豫南地区，信阳市发病最多，占全省病例总数的97.59%，其年均发病率为17.22/10万，高于全省平均发病率（0.98/10万）水平（P<0.01）。6个县（区）有死亡病例报告，占病例报告县（区）总数的23.08%。河南省SFTS存在局部空间区域高度聚集和个别县（区）散在发生两种发病模式。河南省报告SFTS病例的县（区）数逐年增多，疫区范围不断扩大，呈现由南向北逐渐扩散趋势。 结论： 河南省SFTS发病具有时间上的季节性和空间上的高度聚集性特征，应针对其时空分布特征和发病趋势，制定有效防控措施。.
