Abstract:Objective To analyze the epidemiologic features of hepatitis E in Hunan Province, and to provide evidence for its prevention and control. Method The data of hepatitis E cases in Hunan Province from 2006 to 2014 were collected from the Infectious Diseases Reporting Information System of China Information System of Disease Prevention and Control. The distribution and epidemic characteristics of hepatitis E were analyzed by Excel 2003 and ArcGIS(10.2) softwares. Results A total of 7,124 hepatitis E cases were reported in 2006-2014, with an average annual incidence rate of 1.22/100,000. Overall, the incidence showed an upward trend. The ratio of male cases to females was 2.95:1. The cases distributed among all age groups, with the most cases (25.77%) in the 40-years group. As for occupational distribution, the peasants ranked the first, with 3,858 cases and accounting for 54.15%. With regard to the regional distribution, Huaihua City had the highest incidence, while Loudi City had the lowest. Conclusions The incidence of hepatitis E in Hunan Province in 2006-2014 shows an upward trend. Most of the hepatits E cases are peasants aged ≥40years, and mainly cluster in the northern and western parts of Hunan Province. It is necessary to strengthen the monitoring and comprehensive prevention and control of hepatitis E.
