Methods Descriptive epidemiological method was used to describe epidemiological characteristics of HFMD in Hinggan from 2009 to 2013, and analytical statistical method was used to analyze pathogen-detecting results. Results 3655 cases of HFMD were reported in Hinggan from 2009 to 2013, and the morbidities in each year were I13.71/100000, 32.09/100000, 18.78/100000, 27.64/100000 and 27.49/100000 respectively.
