Abstract：Objective To investigate the incidence trend and epidemiological characteristics of Japanese encephalitis (JE) in Handan city so as to provide evidence for formulating JE prevention and control strategies in future. Methods Descriptive epidemiological method was applied to collating and analyzing the epidemiologic features of reported cases of JE in Handan from 1997 to 2018. Results A total of 290 cases of JE were reported in Handan city from 1997 to 2018, with an average annualincidence rate of 0.15/100,000. All the original 19 counties (cities or districts) reported JE cases, but the incidence of these areas wasuneven. The incidence showed obvious seasonality, and was mainly concentrated in summer and autumn, with the peakincidence occurring in August and September. Most of the cases belonged to the age group of 5 to 9 years, followed by the age groups of 10-14 years, 50-54 years and 60-64 years, and there was an increasing trend towards the elder age group. The top three occupations were farmers, students and scattered children. Conclusions As the incidence of JE in Handan city is low at present, comprehensive measures should be taken for JE prevention and control such as continuing to maintain the high vaccination rate of JE vaccine, focusing on the key population (such as adults) and key areas, conducting health education, carrying out mosquito monitoring work, promptly removing mosquito breeding grounds and controlling mosquito density to a lower level.
