Objective:To analyze the prevalence of hand,foot and mouth disease(HFMD)in China during 2008-2018 and to provide reference for the prevention and control of HFMD.Methods:Literature eligible for selection was retrieved from the China's national knowledge infrastructure project(CNKI),and data from 2008-2018 Chinese HFMD reports were systematically analyzed.Excel and SPSS 20.00 were used for statistical analysis,and GraphPad Prism 6 was used for mapping.Results:The analysis showed that the average incidence rate of HFMD in China from 2008 to 2018 was 123.37±93.14 cases per 100,000 people,with a male-to-female ratio of(1.50±0.15):1,and the vast majority of cases were concentrated in the under-5 age group,mainly in scattered children.The time of onset of HFMD showed obvious seasonal characteristics,in which single-peak provinces were higher than double-peak provinces,with double-peak trends in April-July and October-November,respectively,and single-peak trends mainly in May-July.Based on the spatial distribution study,the incidence pattern showed obvious regional differences(P<0.05),with high incidence concentrated in the southeastern part of the country,and a gradual increase in incidence from west to east and north to south of China.EV71,CA16 and other enteric viruses were the main pathogens of HFMD,with EV71 accounting for 53.5%,CA16 is accounting for 14.3%and other enteric viruses accounting for 32.2%of the pathogens.Conclusions:The incidence of HFMD in China is high,with obvious geographical,seasonal,gender and age distribution characteristics.According to the pattern of HFMD incidence in the region,early prevention and control of key areas and groups is an effective way to cut off the spread of the disease.
