To analyze the epidemic characteristics of infectious disease public health emergencies in Beijing in recent 10 years, and to provide reference for the prevention and control of infectious disease public health emergencies.
Descriptive epidemiological methods were used to analyze the occurrence characteristics of public health emergencies of infectious diseases in Beijing from 2014 to 2023.
From 2014 to 2023, a total of 443 public health emergencies of infectious diseases were reported in Beijing, with 7 334 cases and 20 deaths. The incidence rate was 1.56% and the fatality rate was 0.27%. There were 240 unclassified incidents (54.18%) and 202 general incidents (45.60%). The main categories were Class B incidents and Class C incidents, with 202 events (45.60%) and 98 events (22.12%) reported respectively. The main transmission routes were life contact transmission, water and food transmission and vector animal and plant transmission, with 192 evens (43.34%), 36 evens (8.13%) and 29 evens (6.55%) reported respectively. The main occurrence places were home and school, with 215 events (48.53%) and 136 events (30.70%) reported respectively. The peak months were June-August and January-February, with 149 events (33.63%) and 105 events (23.70%) reported respectively. The prediction accuracy of the grey model GM(1,1) is excellent, but the difference between the predicted value and the actual value in 2020-2023 is large.
The COVID-19 pandemic has significantly changed the rising trend of public health emergencies of infectious diseases in Beijing, but the prevention and control work in the post-COVID-19 era should not be ignored, and the comprehensive prevention and control of key infectious diseases and imported infectious diseases should be strengthened in key seasons and places.
