Abstract:
Objective To analyze the epidemiological characteristics of HFRS and rodent monitoring data in JiangXi province from 2012 to 2017, so as to provide scientific basis for controlling HFRS prevalence. Methods Descriptive epidemiological method was adopted to analyze the changes in time, region, and population morbidity of HFRS and rodent monitoring data from 2012 to 2017 in the province. Results From 2012 to 2017, there were 3 763 HFRS cases with 33 deaths reported in JiangXi province, the incidence was 1.38/100 000, the case fatality was 0.88%.The incidence in males was significantly higher than that in females( 2＝452.282, P<0.001).In the composition of occupation,the proprotion of farmers was decreased, while household workers, workers waiting for employment, students and other occupations were increased.There were two peaks in spring (from May to June) and winter (from November to January), and the winter peak was obviously higher than the spring peak. The average rat density at the two surveillance areas was 3.63%. Rattus norvegicus was predominant in residential areas and Apodemus agrarius was predominant in the wild.The six years on average index of rats with virus was 0.04. Conclusion The incidence of epidemic hemorrhagic fever in JiangXi Province generally showed an upward trend from 2012 to 2017, which suggest that we should continue to strengthen comprehensive prevention and control measures: rodent control in high-incidence areas, popularize vaccination and replenishment, and carry out health education for the whole population.
