Epidemiological analysis of hand-foot-mouth disease in Beijing from 2007 to 2010

Abstract

Objectives To examine the epidemiological characteristics of hand-foot-mouth disease (HFMD) in Beijing from 2007 to 2010, and to provide evidence for the prevention and control of HFMD.Methods The monitoring data of HFMD, from 2007 to 2010 in Beijing, was analyzed by descriptive epidemiology. Results There were 99325 reported HFMD cases in Beijing from 2007 to 2010, including 24 cases of death. The yearly number of cases were 11 012, 18 445, 24 483 and 45 385 with 0, 2, 4, 18 case of death respectively, and the incidence was 69.65/105, 112. 90/105, 144.44/105 and 258. 60/105 from 2007 to 2010. Most cases were reported in floating population community. HFMD was reported in all seasons, but most common in spring and summer. Most cases were under 5 years old, and more male cases were found. More deaths were seen in scattered children other than preschool children. Enterovirus 71 (EV71) and Coxsackie virus A16 (CoxA16) were most common pathogens, and all detected EV71 viruses were CA genotype. Conclusion The reported cases of HFMD were increased year by year in Beijing. The prevention and control of HFMD should be strengthened for the children under 5 years old in summer and autumn, especially those children in floating population community.
