Epidemiological analysis of viral hepatitis C in Bazhong City from 2013 to 2022
Objective To analyze the epidemiological characteristics of hepatitis C cases reported in Bazhong City from 2013 to 2022,and to provide basis for formulating effective prevention and control strategies.Methods Data of all hepatitis C cases reported in Bazhong City from 2013 to 2022 were collected.Chi-square test was performed by SPSS 23.0 software,and the test level wasα=0.05.Results From 2013 to 2022,a total of 1 472 cases of hepatitis C were reported in Bazhong City,with an annual average incidence of 4.59/105 and no death cases.The largest number of cases and the highest incidence rate of hepatitis C were found in Pingchang County.There were statistically significant differences in the annual average incidence among counties/districts(x2=254.401,P＜0.001).The incidence of hepatitis C in Bazhong City showed an overall upward trend from 2013 to 2022,and the increase was obvious from 2019 to 2022.In terms of monthly distribution,the cumulative number of reported cases was the highest in March and the lowest in September,and the concentration ratio was M=0.06,indicating poor seasonality.The incidence of males was higher than that of females,and the difference between male and female incidence was statistically significant(x2=10.667,P=0.001).Farmers were the most affected population,accounting for 62.64％.Conclusions From 2013 to 2022,the incidence of hepatitis C in Bazhong City showed an increasing trend,which was the same as the national incidence of hepatitis C.The ability of nucleic acid detection of hepatitis C in medical institutions needs to be improved,and the publicity and promotion of radical treatment programs for hepatitis C RNA(ribonucleic acid)positive cases should be strengthened to reduce the prevalence of hepatitis C.
