[Objective] To analyze the epidemiological characteristics of hand-foot-mouth disease in 2009 in Liaocheng City and provide a scientific basis for the control of hand-foot-mouth disease. [Methods] The information of hand-foot-mouth disease card and RT-PCR laboratory test results collected in various medical institutions of Liaocheng in 2009 were collected and analyzed, and the descriptive method was used for epidemiological analysis. [Results] The incidence of hand-foot-mouth disease in Liaocheng in 2009 was 277.60 / 100 000, with 3 deaths and a case fatality rate of 0.02%. Outbreaks of hand-foot-mouth disease were found in 3 counties. There were 10248 males and 5770 females, 1.8: 1. There were reports of hand-foot-mouth disease in 8 counties (cities and districts) in the whole city, and there was a significant difference in the incidence rates among counties (cities and districts) (P <0.01). From March to September, the incidence peaked; the age ranged from 2 months to 57 years. The highest incidence was 15,504 (96.79%) in children younger than 5 years old in the younger age group. A total of 65 samples were tested, the positive rate of EV71 was 12.31%, the positive rate of COXA16 was 4.62, and the positive rate of other enterovirus was 61.54%. [Conclusion] The incidence of hand-foot-mouth disease in Liaocheng in 2009 is at a high level. Monitoring of hand-foot-mouth disease should be strengthened in people younger than 5 years of age, and laboratory tests should be strengthened.
