ObjectiveTo analyze the epidemiological characteristics of public health seedling events in Fengxian District from 2017 to 2018, and to provide evidence for the prevention and control of key public health seedling events in future.

MethodsData on seedling incidents in Fengxian District from 2017 to 2018 were collected and analyzed by descriptive epidemiological method.

ResultsFrom January 1, 2017 to December 31, 2018, a total of 141 new public health seedling events were reported, of which 2 were public health emergencies. The main diseases were measles, hand, foot and mouth disease, chickenpox, norovirus infection, influenza and tuberculosis. Most of them were in the central and western areas where Fengxian population was clustered. The public health seedling events occurred in the peak of March-June and September-December. The number of incidents involving nursery institutions and primary schools accounted for 65.97%. In 2018, the number of incidents involving nursery schools increased by 41 cases. Of them, hand, foot and mouth disease accounted for 23. The median interval between the onset and event report, event report and closure of events(P₂₅-P₇₅)was 3(2-8)days, 11(8-14)days and 15(11-22.5)days, respectively.

ConclusionWe should pay more attention to the central and western areas where population gathers in Fengxian District. We should pay more attention to measles, hand, foot and mouth disease, chickenpox. CDC departments should train and supervise key collective units(especially kindergartens and elementary schools)before the key seasons, and make appropriate prediction and early warning according to the incidence over the years, and inform relevant personnel that after the occurrence of the seedling events. According to the incubation period and duration of different infectious diseases, follow-up management work should be done well.
