2016-2021年江西省丙型病毒性肝炎流行特征和时空聚集性分析

Epidemiological characteristics and spatiotemporal distribution of hepatitis C in Jiangxi,2016-2021

目的分析江西省丙型病毒性肝炎(丙肝)的流行病学特征和时空聚集性,为丙肝的风险识别、预警和有效防控提供参考依据。方法收集2016—2021年江西省丙肝的监测数据,用ArcGIS 10.2软件进行空间自相关分析,用SaTScan软件进行时空扫描分析。结果2016—2021年江西省累计报告丙肝病例14982例,其中死亡病例4例,年平均报告发病率为5.44/10万,平均病死率为0.03%。报告病例中男性多于女性,年龄集中在40~69岁,职业分布以农民、家务及待业人员、离退休人员为主。空间自相关分析显示,2016—2021年丙肝发病具有一定的空间聚集性,高发区域主要分布在萍乡市、九江市、抚州市和南昌市所辖县(区)。时空扫描分析探测到1个Ⅰ类聚集区和3个Ⅱ类聚集区,Ⅰ类聚集区域主要覆盖萍乡市主城区和周边县(区)。结论江西省丙肝发病具有明显的人群流行特征和时空聚集性。萍乡市、九江市、抚州市和南昌市的主城区及周边临近县(区)为丙肝发病的重点聚集区,需特别关注。

Objective To analyze the epidemiological characteristics and spatiotemporal distribution of hepatitis C in Jiangxi province and provide scientific basis for risk identification,early warning and effective prevention and control of hepatitis C.Methods The surveillance data of hepatitis C in Jiangxi from 2016 to 2021 were collected,spatial autocorrelation analysis was performed with ArcGIS 10.2,and spatiotemporal epidemiological analysis was performed with SaTScan.Results A total of 14982 hepatitis C cases,including 4 deaths,were reported in Jiangxi during 2016-2021.The annual average reported incidence rate was 5.44/100000,and the average case fatality rate was 0.03%.More cases were reported in men,and the cases were mainly aged 40-69 years.The cases were was mainly farmers,the jobless or the unemployed and retirees.Spatial autocorrelation analysis showed that the incidence of hepatitis C had a certain spatial clustering during 2016-2021,and the areas with high incidences were mainly distributed in counties or districts of Pingxiang,Jiujiang,Fuzhou and Nanchang.One class I clustering area and three II clustering areas were detected by spatiotemporal scanning.The class I cluster area mainly covered the urban area and surrounding counties of Pingxiang.Conclusion The incidence of hepatitis C had obvious demographic characteristics and spatiotemporal clustering in Jiangxi.The urban areas and surrounding districts of Pingxiang,Jiujiang,Fuzhou and Nanchang were the key clustering areas of hepatitis C incidence,to which special attention needs to be paid.
