目的了解2005-2014年江苏省戊型病毒性肝炎流行病学特征,为制定有效防控措施提供流行病学依据。方法采用描述流行病学方法,对2005-2014年江苏省报告的戊肝病例流行特征进行分析。结果 2005-2014年江苏省共报告戊肝病例32 931例,年均发病率为4.26/10万,年报告发病率呈现较平稳趋势(Z=3.06,P=0.12)。冬春季为发病高峰,高峰日为3月12日,高峰期为11月29日至次年6月23日;男性发病高于女性,男女发病率之比为2.70∶1,中老年人发病率高,儿童及青少年发病少见,报告病例中农民所占比例最高并逐年升高(Z=163.90,P<0.001);苏南地区的镇江市,苏中地区的扬州市、泰州市和南通市,苏北地区的徐州市和连云港市报告发病水平较高,呈现地区性扩散趋势。结论江苏省戊肝发病率高于全国平均水平,对重点人群和高危人群开展健康宣教,推广疫苗接种免疫,降低该病对广大群众的健康危害。
Objective To understand the epidemiological characteristics of E virus hepatitis in Jiangsu province from 2005 to 2014 and provide epidemiological evidence for effective prevention and control measures. Methods Descriptive epidemiological methods were used to analyze the epidemiological characteristics of hepatitis E reported in Jiangsu Province during 2005-2014. Results A total of 32 931 hepatitis E cases were reported in Jiangsu Province from 2005 to 2014, with an average annual incidence of 4.26 / 100 000. The incidence of annual reports showed a relatively steady trend (Z = 3.06, P = 0.12). Winter and spring peak incidence, the peak day of March 12, the peak from November 29 to June 23 next year; men than women, the incidence of men and women was 2.70: 1, the incidence of the elderly (Z = 163.90, P <0.001). In Zhenjiang City in southern Jiangsu Province, Yangzhou City in Taichung City, Taizhou City and Nantong City in the middle and southern part of Jiangsu Province, the number of peasants in the reported cases was the highest and increased year by year. Xuzhou City and Lianyungang City in northern Jiangsu reported a higher incidence and showed a regional trend of spread. Conclusions The incidence of hepatitis E in Jiangsu Province is higher than the national average level. It carries out health education on key and high-risk groups, promotes vaccination and immunity, and reduces the health hazard of the disease to the general public.
