Methods The epidemic data of hepatitis virus C during 2004 -2012 in Suining city were collected and analyzed by descriptive epidemiological methods.

The report incidence increased from 1.51/10^5in 2004 to 17.79/10^5in 2012 2 （Хtrend^2 = 1000. 15, P 〈0.01） , with an amplification of 10. 78 times. The constituent ratio of hepatitis C in notifiable infectious disease rose from 0. 23% in 2004 to 3. 88% in 2012. The number of reported cases in Chuanshan district was the most, with 1131 cases （51.62%） , followed by Anju district with 371 cases （ 16.93% ） , Shehong county with 316 case （ 14.42% ） and Daying county with the fewest of 161 cases （7.35%）. The reported incidence rate in Chuanshan district in 2012 was the highest （42.37/105） and the lowest was in Shehong county （8.31/105）. No apparent seasonal distribution was found. Incidence in men was higher than in women （Х^2 = 3.44 × 10^7, P 〈 0.01 ） ; the incidence constituent ratio of those aged 1 - 9 years old was 0. 18% （4 cases）, 20 - 59 years old was 59.93% （1313 cases） and those above 60 years old was 37.38% （819 cases）.
