Objective To understand the distribution of HFMD in Wendeng City from 2010 to 2011 and to explore the prevalence of HFMD.

The seasonal distribution in 2010 showed a unimodal distribution and the epidemic peak in 2011 was 2 Month, and the second peak appeared in November, with a bimodal distribution; the cases mainly concentrated in the administrative area of the city; the positive rate of stool specimens was 94.95%; the positive specimens were mainly EV71 and CoxA16, accounting for 46.84% and 31.89% Other EV was 21.26%. EV71, CosA16 is the main pathogen of common cases, while the pathogens causing severe cases are mainly EV71 type.
