Abstract: [Objective] To describe the epidemiological features of hand-foot-mouth disease（HFMD） in Pudong New Area of Shanghai from 2009 to 2012 for control and early warning of HFMD in local residents. [Methods] Data of study population and HFMD cases in Pudong New Area were collected during a four-year timeframe（2009-2012） for descriptive epidemiological analysis on incident distribution, clusters, outbreak, and pathogen surveillance of HFMD. [Results] From 2009 to 2012, a total of 37 345 HFMD cases were reported including 149 severe cases and 7 fatalities. The estimated incidence rate of HFMD was 120.49/105 in 2009 and increased to 248.33/105 in 2012. A seasonal variation of HFMD incidence was also found, with a peak from May to July, followed by a minor peak from November to December. The male-to-female ratio was 1.59. Children under five years old accounted for 93.09% of the total reported cases. Children in geographically dispersed families and those in nurseries or kindergartens composed 95.79% of the reported cases. All subdistrcts and towns of Pudong New Area reported HFMD cases, and the highest incidence rate was 207.68/105 among the subdistricts and 294.30/105 among the towns. A total of 1 566 clustered outbreak events of HFMD largely affected children in nurseries and kindergartens. CoxA16 and EV71 were the main pathogens. [Conclusion] The HFMD incidences are increasing with explicit seasonal variation and gender and age preponderance in Pudong New Area during 2009-2012. We should further study early warning and prediction of HFMD based on routine monitoring and laboratory testing.
