The high - incidence season was in the transition period of Spring to Summer. The onset age concentrated in 5 years or below, with 4794 cases, accounting for 91.16% of the total; children in nurseries and scattered children account for 95.53% of the total cases. Pathogen was predominantly CoxA16 type （39.47%）, followed by virus EV71 （30. 99%） and the rest types （29.53%）. Conclu- sion HFMD prevention and control work should be focused on scattered children and nursery children; mean- while, targeted health comprehensive measures including education should be carried out broadly.
