analyze the epidemiology and etiology of hand-foot-mouth disease data based on the online report of Yuanjiang County from 2009 to
2014. Results: A total of 4 060 cases of hand- foot- mouth were reported in Yuanjiang County from 2009 to 2014, the average
incidence was 330.0/105, and the epidemic curve showed a trend of "M" type. Morbidity peak period has the tendency of shifting from
the autumn to winter and spring, appearing "twin peaks" type distribution. The hand- foot- mouth disease cases were mainly
concentrated in Lijiang Town, Ganzhuang Streets and Manlai Town. Lijiang Town was the top at the number occurred of hand-footmouth
