Abstract:

Objective To understand the epidemiological characteristics and pathogen spectrum of hand, foot and mouth disease (HFMD) in Jilin Province for evidence in scientific prevention and control of this infection. Methods The data associated with HFMD cases and pathogen spectrum reported in Jilin Province from 2017 to 2023 were collected through the Chinese Disease Prevention and Control Information System, and descriptive epidemiological methods were used to analyze the temporal, population and regional distribution of the epidemic. Results In total, 38 393 cases of HFMD were reported in Jilin Province between 2017 and 2023. The average annual reported incidence rate was 21.36 per 100 000 population. Of the reported cases, 12 were severe infection, and no deaths. The epidemic seasons were in July and October, during which a cumulative 31 659 cases (82.46 percent) were reported. The number of reported cases (22 887 cases) and the average annual reported incidence rate (25.33/100 000) were higher for males than for females (15 506 cases, 17.35/100 000). The age of onset of the disease was mainly between 0 and 5 years (27 739 cases, 72.25%). The occupational distribution was dominated by children living at home (15 535 cases, 40.46%), children in nursery and kindergarten (13 693 cases, 35.67%) and students (8 533 cases, 22.23%). Cases of HFMD were reported in every city (prefecture) throughout the province. The top three cities (prefecture) by the number of cases reported were Changchun (10 994 cases, 28.64%), Jilin (7 996 cases, 20.83%) and Yanbian Korean Autonomous Prefecture (7 112 cases, 18.52%). Laboratory studies indicated that EV-A71, CVA16 and other enteroviruses accounted for 11.88%, 20.84%, 67.28%, respectively. The proportion of EV-A71 and CVA16 showed a decreasing trend, while the composition of other enteroviruses was increasing trend. Conclusion Comprehensive prevention and control measures should be carried out in Jilin Province for the key population and key areas during high-incidence seasons of HFMD to reduce its prevalence in the population. Other enteroviruses are gradually becoming dominant serotypes and need close monitoring.
