Results A total of 1,472 cases of HFMD were reported in Rucheng county during the period of 2010 - 2012, with 4 death cases. The incidence of HFMD rose sharply during the period and showed an obvious seasonal peak, which was mainly from April to July. The incidence was significantly ahead of the schedule in 2012, which was concentrated from March to June. HFMD cases were mainly children under the age of 6 years, accounting for 93.88% of the total incidence. The high risk population was children under the age of 4 years, accounting for 75.85 % of the total incidence. The incidence was higher in male than in female. 92.84 % of the cases were scattered children. The monitoring results displayed that the pathogens were EV71, CoxA16 and other enteric viruses. The prevailing strains transformed annually, and EV71 was the predominant strain in Rucheng county in 2012, accounting for 81.63% of the detected specimens. Conclusions The epidemic of HFMD in Rucheng county is severe. It is necessary to strengthen the monitoring of scattered children under the age of 3 years, improve the early identification of severe HFMD, and enhance the comprehensive prevention and treatment of HFMD so as to decline the incidence and death of HFMD.
