[Results]There were 37 520 reported cases from 2007 to 2016 with average age of 2.81 years old, in which 92.05％ cases were aged 5 years old or below. The incidence rate showed fluctuation over years was from the lowest incidence of 217.03/105 in 2015 to the highest of 461.83/105 in 2016. There were 55.95％ of reported cases from the period of April to July and 94.98％ were from rural and urban-rural areas. Samples from 799 patients as pharynx swab and anal swab, etc. were found to be enterovirus 71 (EV71) , the dominant pathogen, accounting for 44.56％ of total isolation. There were 0.59％ severe cases, 96.23％ of which were positive of EV71. [Conclusion] The HFMD prevalence in Jiading District of Shanghai showed periodicity and seasonality. Children aged 5 years old below and living in non-urban areas showed higher incidence risk. EV71 is the dominant pathogen, especially for the severe cases.
