[Objective]To understand the epidemiological characteristics of hand-foot-mouth disease（HEMD）in Shunhe District of Kaifeng City,provide the basis for developing the control and prevention measures.

Etiological surveillance results showed that the positive rate of EV71 reached 55.10%,and 76.92% of severe cases were positive for EV71.[Conclusion]It is necessary to pay more attention to highrisk area and high-risk group,strengthen the etiological surveillance,and take targeted prevention and control measures.
