Abstract:
Objective To understand the epidemiological characteristics of hand-foot-mouth disease(HFMD) in China, and provide evidence for the prevention and control of HFMD and vaccine clinical research design.Methods Using PubMed,China National Knowledge Infrastructure(CNKI) and Wanfang databases as retrieval sources, the Chinese and English articles on epidemiological characteristics of HFMD in China published from 2012 to 2021 were systematically retrieved, and relevant information was extracted. Chi-square test was used for the statistical analysis of the enterovirus detection rate, type composition, the distribution of gender, age, year, season, region and symptoms.Results A total of 327 articles were included in this study, of which 295 were included in the overall detection rate of HFMD enterovirus. The total number of people involved was 4 786 389, the number of enterovirus nucleic acid positive cases was 709 086, and the laboratory-diagnosed cases accounted for about 14. 81% of the total number. The four types with the highest detection rates were Coxsackievirus A6(CA6), enterovirus 71(EV71), CA16 and CA10. A total of 327 articles with 61 serotypes were included in the type proportion, and the four types more than 1% were EV71, CA16, CA6 and CA10, and other types such as CA4, CA2 and CA5accounted for a lower proportion. Among the laboratory-diagnosed cases, there were more men than women, with a sex ratio of about 1. 72∶1; children under 5 years of age were at high risk of HFMD, with 1 year of age being the most and 0 year of age being the least; the composition ratio of enteroviruses varied with the year and season, the proportion of EV71 showed an overall downward trend from 2008 to 2019, and the peak season for HFMD was from April to June. The distribution of HFMD exhibited geographical differences, and the top 5 provinces were: Guangdong, Jiangsu, Hebei, Hunan and Zhejiang; HFMD was mainly common type/mild type, and the proportion of EV71 in severe cases and deaths was significantly higher than that of other types.Conclusion The type composition of HFMD enteroviruses in China was mainly EV71, CA16, CA6 and CA10,while other types such as CA4, CA2 and CA5 accounted for a relatively low proportion. Type distribution varied in sex, age,year, season, region and symptoms.
