Abstract：Objective To collect the laboratory surveillance results of Japanese encephalitis (JE) cases in Maoming city, to analyze the epidemiological and clinical features of JE in recent ten years, and to provide a scientific basis for JE prevention and control. Methods Enzyme linked immunosorbent assay was used to detect the JE IgM antibody in monitored cases of JE in Maoming city from 2010 to 2019, and descriptive epidemiological methods were employed to retrospectively analyze the data ofconfirmed cases. Results A total of 423 monitored cases of JE were reported in Maoming city from 2010 to 2019, including 69 laboratory-confirmed cases and 4 deaths. The average annual incidence rate was 0.11/100,000, and the case fatality rate was 5.80%. The ratio of male to female was 1.76∶1. The epidemic period was mainly between May and June. The regional distribution was in a circular pattern with high incidence. The majority of the patients were scattered children and students. Most of the cases were children aged 2-12 years, and no adult cases were found. The majority of the patients had no immunization history or an unknown immunization history, accounting for 89.86%. The clinical types of the cases were mainly moderate and severe types with obvious clinical symptoms. Conclusions The epidemics of JE in Maoming city have been obviously decreasing in the past ten years, and the JE cases show apparent seasonality, population specificity and regional characteristics of surrounding counties or districts with high incidence. Most of the patients are young scattered children without an immunization history. It is necessary to strengthen the control measures for JE vaccine leakage and catch-up and mosquito eradication among the age-appropriate children and continuously conduct surveillance of JE cases and vectors so as to prevent the outbreak of JE epidemic.
