The proportion of severe cases and the mortality rate showed a decreasing trend (χ2severe cases=282.09, P2mortality=51.33, P2=4 507.84，Pr=-2.85，P22 =521.86，P2proportion of severe cases=93.71，P=0.000，χ2mortality rate=26.62，P=0.000，χ2proportion of EV71=1060.86，P=0.000). Conclusion The incidence of HFMD in Shijiazhuang presented a declining trend, and the dominant etiological changes of different cases were different.
