Objective To investigate the epidemiological characteristics and trends of HFMD in Jinzhou and provide a reliable basis for the prevention and control of the epidemic. Methods Descriptive epidemiological methods were used to analyze the epidemic situation and monitoring results of hand-foot-mouth disease in Jinzhou from 2008 to 2015. Results The incidence of hand, foot and mouth disease in Jinzhou decreased from 2008 to 2015, with a slight rebound from 2011 to 2012, the incidence of HFMD in different years was significantly different (P <0.05). The number of urban cases was higher than that in rural areas The seasonal distribution of HFMD in each year was basically the same. The distribution of HFMD in each year tended to be the same, which began to increase from June to June each year. The number of cases increased from June to September and peaked from July to August. Women, children under 5 accounted for 92.42% of the total number of cases. Among them, 2-year-old to 3-year-old had the largest number of cases, accounting for 50.08%. A total of 924 HFMD cases were diagnosed, accounting for 10.37% of the total. Among them, EV71 positive accounted for 31.71%, Cox A16 33.77% and other enterovirus positive 34.52% . Conclusion Hand, foot and mouth disease in Jinzhou has obvious regional and seasonal differences. Young children and young children are at high risk of HFMD.
