Objective: To analyze the etiological surveillance results of hand-foot-mouth disease in Ulanqab City from 2020 to 2022, and to provide basis for scientific prevention of hand-foot-mouth disease in Ulanqab city. Methods: The samples of hand-foot-mouth cases collected by the Centers for Disease Control and Prevention of each county in Ulanqab City were collected. Real-time fluorescence quantitative PCR (RT-PCR) was used to detect the nucleic acid of enterovirus universal (EV), enterovirus 71 (EV71) and coxsackie virus A16 (CoxA16). Results: From 2020 to 2022, Ulanqab Center for Disease Control and Prevention received a total of 2058 throat swab samples of hand-foot-mouth disease cases, and 90 were generally positive for enterovirus, the positive rate was 4.37%, of which 41 were positive for Cox A16, with a positive rate of 1.99%, and 49 were positive for other types, with a positive rate of 2.38%. The positive rate of nucleic acid detection for hand-foot-mouth disease in different years and different regions was statistically significant (χ2=85.836, χ2=222.672,P＜0.05). Conclusion: From 2020 to 2022, hand-foot-mouth disease show a seasonal distribution in Ulanqab city; the positive rates of hand-foot-mouth disease are different in different regions and different age groups. Different years of hand-foot-mouth disease are dominated by other types of pathogens, suggesting that the region should pay attention to the detection of other enterovirus types, grasp the epidemic etiology and variation, and provide a basis for scientific prevention and control of hand-foot-mouth disease.
