Epidemiological Analysis on Public Health Emergencies in Shanghai during 2009-2013

[Objective] To describe the epidemiological characteristics of public health emergencies in Shanghai and provide scientific evidence and related strategies for efficient response to public health emergencies. [Methods] Descriptive epidemiological method was utilized to analyze the data of public health emergencies from public health emergency reporting system in Shanghai during 2009-2013. [Results] It was reported that there were 266 public health emergencies in Shanghai during 2009-2013. Specifically, 46.6 percent of the events were infectious diseases, the majority of which were respiratory infectious diseases, such as chicken pox; 86 heat stoke events(32.3%) were reported and caused 103 deaths; 44 people died in 35 occupational poisoning events. The peaks of infectious disease events occurred in April and December, while the majority of heat stoke events occurred in July and August. There was a significant difference in month distribution for different events(P 0.05). The infectious diseases events were most common in schools(0.027%), especially in primary schools. The intervals were 3 hours between online reporting and CDC informed on average. [Conclusion] There has been significant improvement in the timeliness of public health emergency online reporting. The prevention of infectious disease events should be focused on primary schools, vaccination management, and regular surveillance. It should be given priority to decline mortality rate and fatality rate in occupational poisoning events.
