Abstract：Objective To investigate the epidemiological characteristics of clusters of fever epidemic in Pudong New Area from 2013 to 2015 so as to provide evidence for formulating effective prevention and control measures. Methods The epidemiological data of clusters of fever epidemic in Pudong New Area during 2013-2015 were collected and analyzed. Results Sixty clusters of fever epidemic were reported in Pudong New Area from 2013 to 2015, and the number of cumulative cases was 1,585. The reports of the clusters concentrated in December of each year, and a total of 29 (48.33%) clusters were reported. The reported sites were mainly distributed in primary and secondary schools, with a total of 47 (78.33%) clusters. The main viruses detected were type B and A (H3N2) influenza viruses, accounting for 48.33% of the total clusters. Conclusions The clusters of fever epidemic in Pudong New Area during 2013-2015 are mainly caused by type A and B influenza viruses and concentrate in winter. Special attention should be paid to primary and secondary schools in prevention and control of the epidemic.
