Abstract：Objective To investigate the epidemiological characteristics of hand, foot, and mouth disease (HFMD) in border counties of Yunnan Province so as to provide a basis for formulating prevention and control strategies and conducting cross-border collaborative surveillance of infectious disease. Methods Ordinal clustering method (OCM) and hierarchical clustering analysis method (HCAM) were employed to analyze the data of number and incidence of reported HFMD cases in 25 border counties of Yunnan Province during 2011-2016 regarding different months, age groups, counties and districts. Results The distribution of HFMD cases in different months was classified into three groups (the groups of January-March, April-June and July-December) based on OCM and three groups (the groups of January, April, July and September, May-June and October-December, February-March and August) based on HCAM. The distribution of HFMD cases in different age groups was classified into three groups (the age groups of 0- year, 1-3 years and 4- years and above) based on OCM and four groups (the age groups of 1- year, 2-years, 0- year and 3-4 years, and 5- years and above) based on HCAM. According to the average incidence rate of HFMD in 2011-2016, 25 border counties were divided into four levels (level I: Ruili City and Yingjiang County, level II: Jinghong City, Menghai County, Mengla County and Mang City and levels III and IV: the rest of the counties). The incidence rates of HFMD in counties of levels I and II were significantly higher than those in counties of levels III and IV. Conclusions Among the 25 border counties in Yunnan Province, the epidemiological characteristics of HFMD cases in different months, age groups and counties are diverse. It is necessary to strengthen HFMD prevention and control among the key counties and target population.
