[Objective] To analyze the epidemiological characteristics of hepatitis C in Xuzhou City from 2010-2015,provide scientific basis for the effective control of hepatitis C.[Methods]The epidemic data of hepatitis C were analyzed by the descriptive epidemiology. [Results]There was an increasing trend in the incidence of hepatitis C from 2010 to 2015,and the average annual incidence was 5.28/lakh. The incidence increased significantly in Pizhou City and Quanshan District nearly six years,and the seasonal distribution of hepatitis C was not obvious. The cases were mainly adults over 20 years old,and patients aged 1-14 years old were rare. The proportion of patients aged 20-39 years old,40-59 years old,and 60 years old and above was 20.27%,43.54%and 32.97%,respectively. The incidence of hepatitis C in ≥45 year-old age group was higher than that in 44 year-old age group,and the incidence in 45-84 year-old age group increased during these years. The case number and incidence of males were higher than those in females. Most of patients with hepatitis C were farmers.[Conclusion]There is an increasing trend in the incidence of hepatitis C in Xuzhou City from 2010 to 2015.
