Abstract:Objective To analyze the epidemic features of viral hepatitis C (hepatitis C for short) in Pingdingshan City, Henan Province from 2017 to 2021, and to provide a scientific basis for developing measures to eliminate hepatitis C. Methods We collected the data regarding the reported cases of hepatitis C in the Information Management System for Infectious Disease Reporting, and analyzed the prevalence and distribution characteristics of hepatitis C by using descriptive epidemiological methods. Results A total of 2,843 cases of hepatitis C were reported in Pingdingshan City from 2017 to 2021, with 1,618 confirmed cases (56.91%) and the average annual incidence rate being 14.06/100,000. The total number of cases and the incidence rate showed a trend of rising first and then falling. The male to female ratio of hepatitis C incidence in the city was 1.25∶1. No obvious seasonal characteristics were observed. The incidence rate of hepatitis C was slightly higher in urban areas than in suburban counties (16.22/100,000 vs. 14.27/100,000). The cases were mainly concentrated in middle-aged and elderly people over 40 years old (89.69%), and the occupation distribution was mainly farmers (63.14%). Conclusion The incidence of hepatitis C in Pingdingshan City has obvious population and spatial distribution characteristics. The vast rural areas are key areas, and farmers and people over 40 years old are key groups. Health education and interventions are needed to curb the spread of hepatitis C.
