Objective To understand the epidemiological characteristics and trends of hepatitis C in Henan Province,so as to provide evidence for prevention and control measures.Methods The data of hepatitis C cases reported in Henan from 2013 to 2023 were extracted from China Disease Prevention and Control Information System;descriptive analysis for the epidemiological characteristics of hepatitis C cases was conducted.Jionpiont 5.1.0.0 software was used to analyze the trend of hepatitis C epidemic in Henan from 2013 to 2023.Results A total of 236 668 cases of hepatitis C were reported in Henan from 2013 to 2023,with an average annual reported incidence of 19.43/100 000.The overall reported incidence showed a downward trend(From 2013-2021,APC=-8.09％,95％CI:-11.15％-4.92％,P＜0.05;from 2021-2023,APC=22.48％,95％CI:-14.67％-75.80％,P＞0.05).The reported incidences in males and females were consistent with the overall incidence,and the proportion of male cases showed an upward trend(AAPC=2.29％,95％CI:1.75％-2.84％,P＜0.05).The most case-concentrated age group was the group of 45-64 years old,accounting for 57.25％of the total reported cases,and the incidence showed a downward trend(From 2013-2021,APC=-5.58％,95％CI:-8.48％-2.60％,P＜0.05;from 2021-2023,APC=21.34％,95％CI:-11.94％-67.19％,P＞0.05).Farmers were the main occupation,accounting for 71.83％of the total cases,and the proportion increased year by year(AAPC=1.93％,95％CI:1.50％-2.36％,P＜0.05).The cities with the top five morbidities were Zhengzhou(53.55/105),Zhumadian(32.33/105),Luohe(28.25/105),Jiaozuo(26.71//105)and Xuchang(25.24/105),higher than the average annual incidence in the whole province.Conclusions The incidence of hepatitis C in Henan shows a downward trend,but it is still necessary to pay close attention to the key population and key areas and take targeted prevention and control measures for reducing the occurrence of the disease and infection.
