Analysis on epidemiological characteristics of clustering infection of hand-foot-mouth disease in Hedong District of Tianjin from 2019-2021

Abstract

Abstract: Objective To analyze the epidemiological characteristics and trends of the clustering infection of hand-foot-mouth disease（HFMD） in Hedong District of Tianjin,provide evidence for the prevention and control of HFMD. Methods The data were collected form the China disease control and prevention information system to create an Excel database,and SPSS21.0 statistical software was used for statistical analysis. Results A total of 66 clustering infections of HFMD were reported in Hedong District of Tianjin from 2019-2021,a total of 213 cases were found,and there was no outbreak. The clustering infection of HFMD in private kindergartens accounted for 22.73%,and the cumulative cases accounted for 34.27% of the total cases. The high incidence period of HFMD was from June to August,which was consistent with the trend of reported cases. The age mainly concentrated in 3-5 years old,accounting for 53.05% of the total cases. The epidemic was mainly detected by the district-level center for disease control and prevention,accounting for 78.79% of the total epidemic. The average duration of the epidemic was （3.74±5.83）days. The average time interval from the first case to the clustering infection reporte was （4.45±3.55）days. The coxsackie virus A6（Cox A6） and coxsackie virus A16（Cox A16） were the main pathogens in the clustering infection. Conclusions The most important work of HFMD prevention and control should focus on the management of private kindergartens. June-August is the key period to prevent HFMD. The duration of clustering infection is mainly related to the timeliness of epidemic detection,timeliness of investigation and disposal,timeliness of implementation of suspension of classes and other prevention and control measures. Strengthening surveillance of HFMD,early detection,early diagnosis,early report,early isolation and timely implementation of prevention and control measures are the key to control the epidemic situation.
