Abstract：Objective To investigate the epidemiological features of public health emergencies in Changsha City during 2004-2015 so as to provide references for prevention and control of public health emergencies. Methods Data about public health emergencies in Changsha City from 2004 to 2015 were systematically collected from Public Health Emergency Management Information System, and analyzed by SPSS software. Results A total of 289 emergency public health events were reported in Changsha City during 2004-2015, of which 189 (65.40%) were general events, 249 (86.16%) infectious disease events and 25 (8.65%) poisoning events. Most of the public health emergencies occurred from March to June and from September to December, with two peaks in September and November. The proportion of infectious disease events reported in the urban area was significantly higher than that in the four 4 counties (91.74% vs. 82.14%, χ2=5.428, P=0.02), while the proportion of reported poisoning emergencies was lower (1.65% vs. 13.69%, χ2=12.898, P<0.001). 215 (74.39%) emergencies occurred in schools, most of which occurred in elementary schools (55.81%, 120/215).Conclusions Public health emergencies in Changsha City during 2004-2015 mainly occur in autumn and winter, and in schools. It is necessary to strengthen the prevention and control measures of infectious diseases in schools.
