Methods The reported data of Hepatitis C cases in Changsha during 2005 and 2014 were collected, and epidemiological descriptive method was adopted to analyze the data. Results The averagereported incidence rate was 11.02 /100,000 per year in Changsha during 2005- 2014, which was increased through years bySpearman＇s rank correlation analysis（r = 0.95,P 〈0.001）, and no obvious seasonal variation was observed for the incidence ofHepatitis C. However, urban area（Furong District, Tianxin District, Yuelu District, Kaifu District and Yuhua District） hadhigher reported incidence rate than rural area（Changsha County, Wangcheng District, Liuyang City and Ningxiang County） withχ2=1677.011 and P〈0.001, and higher incidence rate was also observed in males（χ2=91.239,P〈0.001）. There were significantdifferences of incidence among differrent age groups by Chi-square test（χ2= 2118.329,P〈0.001）, the reported incidence rateof the high age group was quite higher than that of the middle and low age groups, and low age groups and low age groups hadthe lowest incidence rate. The proportions of farmer cases ranked highest was farmer（23.7%）, followed by house- worker/unemployer（15.8%）, retired people（12.9%）and worker（8.1%）. Conclusion The reported incidence rate of Hepatitis C has atendency to increase in Changsha, and prevention and control measures should be strengthened.
