Abstract: Objective To analyze epidemiological characteristics of hand foot mouth disease (HFMD) in Hainan province, and to provide the scientific basis for its prevention and control. Method The data of HFMD were collected from Chinese Disease Surveillance System and etiology detection results of HFMD were analyzed with descriptive epidemiological methods. Results A total of 50 716 HFMD cases, including 976 severe cases and 33 fatal cases, were reported in Hainan in 2011.The reported incidence was 584.86/10⁵ in 2011.A total of 47 715 HFMD cases, including 512 severe cases and 8 fatal cases, were reported in Hainan in 2012.The reported incidence was 543.83/10⁵ in 2012.There were two peaks of the incidence, from April to July (March to May) and from September to November.Most of cases were children aged<5.There was the highest incidence rate in the age group of 1~2 years(13 766.25/10⁵).The gender ratio was 1.79∶1.Most of cases lived sporadically.The proportion of EV71 strains in severe cases and fatal cases was higher than mild cases.The ratio of severe HFMD cases was increased with the proportion of EV71 strains(r=0.601, P=0.000). Conclusion Hainan province is the high prevalence area.Carrying on etiology surveillance, strengthening the prevention and control measure on the main groups and the key site are the main strategies for management of the disease.
