Analysis on epidemiological characteristics of school public health emergencies in Nanjing City from 2004 to 2022
Objective To Analyze the epidemiological characteristics of school public health emergencies(PHEs)in Nanjing City from 2004 to 2022,so as to provide a scientific evidence for formulating targeted prevention and control policies and measures.Methods The data were collected and organized from National Public Health Emergency Reporting System and analyzed by descriptive method.Results From 2004 to 2022,a total of 228 PHEs were reported in Nanjing City,98.25％(224 PHEs)of which were caused by infectious diseases,with chickenpox(114 PHEs),as the first,followed by other infectious diarrhea,influenza and mumps.There were three turning points in the annual percentage change of PHEs from 2004 to 2022,namely in 2006,2014,and 2019,the three changes after 2006 were statistically significant(all P＜0.05).There were two peaks throughout the year,with November December being the peak period.The reported incidence of emergencies in the southern suburbs of Nanjing City was relatively high,and there was a statistically significant in spatial autocorrelation in Nanjing City(Moran's I=0.123,Z=2.24,P=0.025).PHEs mainly occurred in primary schools and kindergartens(73.25％).The types of infectious disease incidents involved in emergencies in schools of different years and age groups were different.The discovery of the incident mainly relies on reports from medical institutions and schools.Conclusions From 2004 to 2022,there were differences in the main diseases of PHEs in Nanjing City,with chickenpox and primary school being the key diseases and stages for emergency prevention and control.We should do a good job of tracking and monitoring,strive to proactively detect and deal with the epidemic in the early stage of the event,and conduct timely epidemic analysis to grasp the characteristics and changes of PHE.
