Abstract: Abstract: Objective   To analyze the epidemiological characteristics of hand, foot and mouth disease(HFMD) in Luojiang District of Quanzhou City for evidence to plan scientific prevention and control measures for this prevalence. Methods   The data on HFMD in Luojiang District were retrieved from January 1, 2011 to December 31, 2020 through the data of infectious disease reported in the China Disease Prevention and Control Information System, and descriptive statistical method was used to analyze the distribution characteristics of the time, area and population. Results   In total, 7 319 cases of HFMD were reported in Luojiang District between 2011 and 2020. Only one case was serious, yet no death occurred. The incidence rate was between 25.00 and 493.27 by 100 000 population, and the annual incidence was 324.14/100 000 population. The incidence rate tended to decrease year by year (χ²_trend=118.98, P<0.05). The number of cases peak mainly occurred in spring and summer, followed by autumn. Cases of HFMD occurred in all streets/towns, including Wan'an Community (26.55%, 1 943/7 319), Majia Town (25.55%, 1 870/7 319) and Shuangyang Community (18.66%, 1 366/7 319), which accounted for 70.76% of the total incidence. There were 4 721 male cases and 2 598 female cases (male to female ratio: 1.82∶1). The cases were dominant in children living in the diaspora (69.95%, 5 210/7 319), followed by those in early childhood care (27.18%, 1 989/7 319). This disease was most frequent in children under 5 years, accounting for 91.57% of the total number of cases. Conclusion   HFMD represents periodic and seasonal changes in Luojiang Distrct, and are more prevalent in children under 5 years of age, suggesting that this group of children are needed to receive enhanced prevention and control of HFMD.
