Methods Descriptive epidemiological methods were adopted to analyze the characteristics of the HFMD cases. Results Four thousand one hundred and forty-three cases were reported in Jurong from 2009 to 2013. The average morbidity was 133.89 per 10, 000 annually. Thirty-nine severe cases and zero death cases were reported. November was the peak for HFMD outbreaks each year and June tended to be another peak since 2010. The cases mainly occurred in children aged from one to six （93.99%）, while the scattered and pre-school children accounted for 50.93% and 45.33%, respectively. All of the 17 aggregation outbreaks happened in preschools. Two hundred and forty-six cases were diagnosed by laboratory test, in which enterovirus 71 （EV71）, coxsachievirus group A （Cox A） and other enterovirus accounted for 41.46%, 32.11% and 26.42% respectively. Three hundred and ninety-nine active monitoring samples were collected and the positive rate was 54.64%. In 2009 and 2012, the superiority epidemiologic enterovirus strain was Cox A16. In 2010-2011, the superiority epidemiologic enterovirus strain was EV71. And in 2013, the superiority epidemiologic enterovirus strain was other enterovirus, while the superiority strain was EV71 for the severe cases. Conclusion HFMD was observed to be continuously prevalent in Jurong from 2009 to 2013. The cases were alternately caused mainly by EV71, CoxA and other enterovirus, which existed simultaneously. Scattered and pre-school children were high-risk groups while preschools were the high-risk places. Health education and prevention should be strengthened.
