Epidemiological characteristics of the public health emergencies in Changping district,Beijing,2006-2023
Objective To characterize the epidemiological features of public health emergencies that occurred in Changping District of Beijing City in recent years,to provide scientific support for promoting prevention and control levels and strengthening response capability on such episodes.Methods Public health emergencies and related information reported in Changping District(January 2006 to December 2023)were obtained from the National Public Health Emergency Reporting and Management System.A descriptive epidemiological analysis was conducted on factors such as event level,type,and temporal and spatial distribution in the emergency episodes.Results From 2006 to 2023,a total of 1 219 public health emergencies were reported in Changping District(an annual average of 68 incidents),involving 2,097 cases(an annual average of 117 cases),showing an overall decreasing trend in the annual number of incidents.The emergencies were mainly classified as general level(Class Ⅳ,31 incidents,all infectious disease events)and unclassified events(1 183 incidents,including 1 141 non-occupational carbon monoxide poisoning episodes and 34 infectious disease episodes);there were no major level(Class Ⅲ),significant level(ClassⅡ),or particularly significant level(Class Ⅰ)public health emergencies.Non-occupational carbon monoxide poisoning accounted for the highest proportion of public health emergencies,occurring predominantly in winter months(November to March),with incidents mainly occurring in households(1 091,95.62%).Infectious disease emergencies mainly emerged in February and summer months(June to August),with incidents mainly occurring in households(42 cases,60.00%)and schools(25 cases,35.71%),involving diseases such as cholera,chickenpox,type A influenza(H1N1),and novel coronavirus infection.Meanwhile,the emergencies were mostly located in the streets/towns with higher population density and larger numbers of floating populations,such as Huilongguan Street,Dongxiaokou Street,Beiqijia Street,and Shahe Town.The median reporting time for public health emergencies in Changping District during 2006-2023 was 0.29 days,with a positive correlation between the discovery-to-reporting time and the duration of infectious disease outbreaks(rs=0.429,P<0.01).Conclusions Non-occupational carbon monoxide poisoning and infectious disease outbreaks are the major causes as well as priorities of public health emergencies in Changping District.The urban-rural fringe areas are high-risk and key areas for the management of such emergencies.For public health emergencies caused by cholera,chicken pox,novel coronavirus infection,and other infectious diseases,comprehensive measures such as strengthening epidemic monitoring,expanding vaccination coverage,and improving handling capacity should be taken to enhance the response capability and raise the prevention and control level on such emergencies.
