Abstract:
Objective:To analyze the epidemiological characteristics of hepatitis C in Wenzhou City, Zhejiang Province from 2005 to 2023, so as to provide the evidence for improving hepatitis C prevention and control measures.
Methods:The data of hepatitis C cases in Wenzhou City from 2005 to 2023 were collected from the China Disease Prevention and Control Information System. Descriptive epidemiological methods were used to describe the incidence of hepatitis C by gender and age in Wenzhou City from 2005 to 2023. Average annual percent change (AAPC) was used to analyze the trend of hepatitis C incidence.
Results:A total of 15 707 hepatitis C cases were reported in Wenzhou City from 2005 to 2023, with an average annual reported incidence of 9.17/100 000. The reported incidence showed an overall upward trend (AAPC=2.401%, P<0.05). In terms of occupation, farmers/migrant workers and workers accounted for 34.26% (5 382 cases), followed by domestic workers, those engaged in housework and unemployed people, accounting for 19.39% (3 045 cases). Lucheng District, Pingyang County, and Yongjia County had relatively high average annual reported incidences of hepatitis C, which were 18.12/100 000, 13.53/100 000 and 9.88/100 000, respectively. There were 10 816 males and 4 891 females, with a male-to-female ratio of 2.21∶1. The average annual reported incidence of hepatitis C in males was higher than in females (12.06/100 000 vs. 6.00/100 000, P<0.05). The reported incidence of hepatitis C in males showed an overall upward trend (AAPC=3.011%, P<0.05), but there was no significant change in females (AAPC=1.803%, P>0.05). The case was mainly aged 25-<55 years (12 659 cases, 80.59%). There was no significant change in incidence of hepatitis C in 0-<10 years old group and 10-<20 years old group (AAPC=2.103%, 1.126%, both P>0.05), while the incidence of hepatitis C in 20-<30 years old group and 30-<40 years old group showed downward trends (AAPC=>-13.160%, -7.159%, both P<0.05). There were upward trends in the 40-<50 years old group and 50-<60 years old group (AAPC=10.457%, 11.831%, both P<0.05), but no significant change in the ≥60 years old group (AAPC=2.867%, P>0.05).
Conclusions:The reported incidence of hepatitis C in Wenzhou City showed an overall upward trend from 2005 to 2023. Lucheng District, Pingyang County, and Yongjia County were high risk areas. Farmers/migrant workers, workers, males, and people aged 40-<60 years were the key population for prevention and control of hepatitis C.
