Abstract:

【Abstract】 Objective  To analyze the epidemic characteristics and patterns of the hand foot and mouth disease(HFMD) in Hunan province in 2015 for supplying scientific information to plan preventive and control measures for this disease. Methods  The data on HFMD cases, pathogens and outbreaks in Hunan in 2015 were collected from national diseases information reporting system for descriptive epidemiological analysis. Results  A total of 135,628 cases of HFMD, including 710 severe cases and 14 fatal cases, were reported in Hunan in 2015, the morbidity was 201.32 per 100 000 population. Prevalence was higher in the middle, northeast and west areas of Hunan. The male-to-female ratios of incidence were 1.56:1, and the children younger than 5 years old accounted for 97.01% of the total reported cases. The positive ratio by etiology monitoring was 54.02%, and detected EV71 in mild, severe and fatal cases was 9.62%, 29.48% and 88.89% respectively. Conclusion  HFMD appears in seasonal prevalence in Hunan province, and risk groups are associated with younger children and children living scattered areas. Virus of different serotype may be superseded in the epidemic seasons. Therefore, it is critical to strengthen the surveillance and effective response to the prevalence as well as provide health education for the targeted population in prevention and control of HFMD.
