目的探讨2011-2016年江苏省肾综合征出血热流行特征。方法对国家疾病监测信息报告管理系统中2011-2016年江苏省肾综合征出血热疫情资料进行描述性流行病学以及时空重排扫描统计方法分析。结果2011-2016年江苏省累计报告肾综合征出血热1 733例。年均发病率为0.36/10万,男女性别比为1∶0.30;40~岁和50~岁年龄组发病较多;职业分布以农民为主(78.71%),家务及待业构成比逐年上升(χ~2趋势=4.446,P=0.035);全年疫情呈现双峰分布,最高峰出现在每年的10月至翌年1月,次高峰出现在每年的4~6月。时空扫描发现在区县尺度上有时空聚集性,根据总病例分布探测到5个时空聚类区域。结论 21世纪以来,江苏省肾综合征出血热疫情时有抬头,全省各地区地区流行强度不同,发病存在时空聚集性,在高发地区应持续做好控制工作,预防出现聚集性疫情。
Objective To explore the epidemiological characteristics of hemorrhagic fever with renal syndrome in Jiangsu Province from 2011 to 2016. Methods Descriptive epidemiology and spatiotemporal rearrangement scan of statistical data of epidemic situation of hemorrhagic fever with renal syndrome in Jiangsu Province from 2011 to 2016 in the National Disease Surveillance Information Reporting Management System were analyzed. Results In 2011-2016, a total of 1 733 cases of hemorrhagic fever with renal syndrome were reported in Jiangsu Province. The average annual incidence rate was 0.36 / 100000, male to female ratio was 1:0.30; 40 to 50 years old and 50 to the age group had more morbidity; the occupational distribution was dominated by peasants (78.71%), and the ratio of domestic and unemployed workers increased year by year χ ~ 2 trend = 4.446, P = 0.035). The epidemic situation showed bimodal distribution throughout the year, with the highest peak occurring from October to the following January each year and the next peak occurring from April to June each year. Spatial and temporal scanning found spatial and temporal clustering on the scale of county and county, and detected five spatiotemporal clusters according to the total case distribution. Conclusions Since the 21st century, the epidemic situation of hemorrhagic fever with renal syndrome in Jiangsu Province has been on the increase. There are different epidemic intensities in different regions of the province. There is spatiotemporal aggregation in the incidence of the disease. Control work should be continued in high incidence areas to prevent the occurrence of epidemic of aggregation.
