目的分析辽宁省甲型病毒性肝炎(甲肝)流行特征。方法通过中国疾病预防控制信息系统收集2008-2022年辽宁省甲肝发病数据,描述性分析甲肝发病率和分布特征。结果2008-2022年辽宁省共报告甲肝21064例,年均报告发病率为3.28/10万;其中2008-2012年、2013-2017年、2018-2022年报告发病率分别为2.87/10万(5948例)、4.09/10万(8982例)、2.84/10万(6134例),各年龄组报告发病率在0-4岁的0.60/10万(83例)至35-39岁的7.45/10万(3852例)之间。农民、家务/待业人员分别占总报告病例数的37.31%、29.07%。结论2008-2022年辽宁省甲肝发病呈现波动流行和总体下降趋势,<15岁儿童发病率低而青壮年发病率高。需继续做好适龄儿童甲肝疫苗接种,探讨高危成人免疫预防策略。
