Objective To study and analyze the related data to emergent public health events in 2008 Wenchuan Earthquake and two years before and after the earthquake, to examine the emergent health control system of Sichuan in terms of organization, implement, current status and problems, so as to offer first-hand data and decision-making references to the perfection of the monitoring system and raising the effect of control and prevention of the emergent public health envents effect. Methods The report data were statistically analyzed by Excel, EpiInfo software. Results Between 2006 and 2010, the emergent public health events in Sichuan had reduced gradually year by year, and a wave trough was formed in 2008 when Wenchuan Earthquake attacked; the emergent public health events in each year mainly took place in two peaks, one was from April to June and the other was from September to November. Compared with the period between 2006 and 2010, five among six heavily afflicted cities and prefectures with 18 heavily damaged counties in 2008 had dropped in the listing of emergent public health events. Between 2006 and 2010, the emergent public health events happening in schools of Sichuan accounted for 75.00%, especially the township primary schools were on the top of each index as place, cause, morbidity and mortality, but there were no serious emergent public health events. Among nine types of emergent public health events, the contagious disease events accounted for 79.30% while the food poisoning events accounted for 14.33%; and the contagious disease events mainly were respiratory tract infection diseases such as chicken pox, mumps and measles, and hepatitis A which were all preventable with vaccine, and accounted for 82.93%. Conclusion The construction of Sichuan’s health emergency system is a good foundation for the handling of emergent public health events. The emergent public health events in the whole province get gradually reduced year by year between 2006 and 2010, and all kinds of emergent public health events have been handled properly. With the national support for the disaster relief of Wenchuan Earthquake, the provincial emergent public health events after the quake in 2008 have scored the lowest level in the history without severe epidemics after the earthquake; and the plan of no severe epidemics within three years after the earthquake has come true with partner assistance in health system. By improving the control of contagious disease, food poison and preventable diseases, the incidence of emergent public health events can be dramatically reduced with lower morbidity and mortality. Only by means of multi-departmental cooperation and social participation for jointly preventing and controlling school emergent public health events, especially for preventing and controlling the contagious diseases in countryside and township primary schools, can all kinds of emergent public health events be timely prevented and controlled with decreased hazard.
