Objective To discuss risk assessments of public health emergency events in regional large-scale activities in order to provide scientific basis for public health policy makings.
Methods The 17th Jiangsu Provincial Sports Games was selected as the subject for the survey. The risk matrix method was employed to assess risk levels of 20 public health emergency events of 5 categories, including catering food, public places, drinking water, infectious diseases, and vector-borne diseases during the large-scale activity. Furthermore, the Borda count method was used to sort risk levels.
Results The risk levels of 20 public health emergency events and 5 categories were identified and sorted. Catering food ranked first among 5 categories of public health emergency events. Bacterial food poisoning ranked first among 7 events in the catering food category. Epidemical hemorrhagic conjunctivitis caused by polluted natatorium water ranked first among 3 events in the public place category. Central municipal water supply pollution tied for the first place with secondary water supply pollution among 3 events in the drinking water category. Respiratory infectious diseases ranked first among 4 events in the infectious disease category. Skin pruritus, poor rest quality, and fidgeting and detesting caused by vector bites ranked first among 3 events in the vector-borne disease category.
Conclusion The integrated application of risk matrix and Borda count is effective in evaluating the risk levels of public health emergency events that occurred during regional large-scale activities, and therefore is worthy of wide pomotion.
