摘要
目的了解近年兰州市某区丙型病毒性肝炎(简称丙肝)感染状况和发病趋势,为当地制定丙肝防控策略提供依据。方法从中国疾病预防控制信息系统—传染病监测报告管理系统中,收集2010—2023年兰州市某区报告的丙肝病例资料,采用描述流行病学方法分析病例的分布特征。结果2010—2023年兰州市某区符合诊断标准的丙肝报告病例共7582例,其中确诊病例占78.28%。年均报告发病率为39.91/10万,总体呈下降趋势(趋势χ^(2)=2996.598,P<0.05)。平均年龄(54.51±16.57)岁,40岁~组报告病例数最多、占23.83%。不同年龄组间男女报告病例数差异有统计学意义(χ^(2)=240.345,P<0.05)。报告病例职业以离退人员居多、占33.88%。结论近年来该区丙肝报告发病率总体下降;应针对高风险人群如中老年人群、家务及待业人员等,加大宣传干预筛查力度,加强基层医疗机构筛查能力。
Objective To investigate the infection status and epidemic trends of hepatitis C virus(HCV)in a district of Lanzhou City in recent years,and to provide evidence for formulating local prevention and control strategies.Methods HCV case data reported from 2010 to 2023 in a district of Lanzhou City were collected from the China Information System for Disease Control and Prevention—Infectious Disease Surveillance and Reporting Management System.Descriptive epidemiological methods were used to analyze the distribution characteristics of cases.Results A total of 7582 reported HCV cases meeting diagnostic criteria were reported in the district from 2010 to 2023,with confirmed cases accounting for 78.28%.The average annual reported incidence rate was 39.91/100000 population,showing an overall downward trend(trendχ^(2)=2996.598,P<0.05).The mean age of reported cases was(54.51±16.57)years,and the highest number of reported cases was in the 40-years age group,accounting for 23.83%.There were statistically significant differences in reported case numbers between males and females across age groups(χ^(2)=240.345,P<0.05).Retired individuals accounted for the largest proportion of reported cases,accounting for 33.88%.Conclusions The reported incidence of HCV in the district has generally decreased in recent years.Targeted efforts should be intensified for high-risk populations,such as middle-aged and elderly,household workers,and the unemployed,including enhanced publicity,intervention,and screening.Additionally,screening capacity in primary healthcare institutions should be strengthened.
