[Objective] To understand the epidemiological characteristics and trends of hand-foot-mouth disease in Wuhou District of Chengdu City and provide a scientific basis for formulating prevention and control strategies of hand-foot-mouth disease. [Methods] Using descriptive epidemiological method, the data of hand-foot-mouth disease in 2009 were statistically analyzed and compared with the historical data of 2008. [Results] Hand-foot-mouth disease was mainly in the age group of 5 years and below, especially in the age of 3 and below, accounting for 97.44% and 90.24% of the total reported cases, respectively. More males than females, with childcare, diaspora and students, accounted for 99.12% of the total reported cases. Shuangnan Street, with a high population density, reported the largest number of cases. The number of reports of suburban agriculture-related clinics in urban areas was higher than that reported in urban areas (χ2 = 5.183, P <0.05). The peak periods were from March to April, from June to July and from September to November, respectively. The distribution of onset time was different from that of last year (χ2 = 176.249, P <0.01). [Conclusion] The prevention and control of hand, foot and mouth disease of migrant children in suburban agricultural areas and highly populated communities and kindergartens and primary schools should be emphasized.
