2017—2021年黄山市丙型病毒性肝炎流行特征分析

Epidemiological analysis of Hepatitis C in Huangshan city in 2017-2021

目的了解黄山市丙型肝炎流行特征,为制订防控措施消除丙肝危害提供参考依据。方法收集传染病报告管理信息系统中丙肝发病资料和传染病报告质量漏报调查资料,采用描述性研究方法分析丙肝的流行特征。结果2017—2021年黄山市累计报告丙肝494例,平均发病率为7.15/10万。报告漏报率为14.4%~38.10%,经校正后报告发病率为8.22/10万~11.60/10万。主城区周边县区报告发病率为7.90/10万,高于远郊山区的5.20/10万(χ^(2)=14.37,P<0.01)。病例主要集中在40岁以上人群,且发病率随着年龄的增加而不断上升(趋势χ^(2)=170.78,P<0.01)。职业以农民(60.12%)、家务及待业(10.53%)和离退人员(10.32%)为主。确诊病例占病例总数的82.59%。结论黄山市丙肝发病呈低水平散发状态,发病有明显的地区和人群分布特征,仍需进一步强化丙肝监测和重点地区、重点人群精准干预。
