Objective To explore the epidemiological characteristics of viral hepatitis in the county from 2009 to 2012. Methods 2324 patients with viral hepatitis in our hospital from 2009 to 2012 were selected. Basic data of each patient were analyzed to discuss their age of onset, occupation and disease classification. Results From 2009 to 2012, viral hepatitis showed a trend of decreasing year by year with the highest average annual incidence of hepatitis B and the lowest of hepatitis E. By etiological typing observed, the highest proportion of hepatitis B, hepatitis A, hepatitis B, non-segregated hepatitis have a lower incidence rate, hepatitis C, hepatitis E there is an increase. Occupational diseases are mainly farmers, students; 20 to 49 years of age higher incidence of illness.

Therefore, the prevention and control of viral hepatitis need to be further improved.
