Abstract:
Objective To analyze the current status of influenza in Inner Mongolia Autonomous Region and provide targeted measures for the prevention and control of influenza in the entire region. Methods We collected data on influenza cases reported in Inner Mongolia Autonomous Region from the "Disease Monitoring Information Report Management System" of the China Disease Prevention and Control Information System from 2018 to 2022. Statistical analysis was performed using IBM SPSS 22.0, and the comparative differences were assessed using the χ2 test. ArcGIS 10.5 was used to create thematic maps. In this study, SaTScan 9.5 was used for spatiotemporal scanning analysis of influenza incidence data in the entire region from 2018 to 2022, conducting retrospective spatiotemporal reordering scans. Results From 2018 to 2022, a total of 25 485 cases of influenza were documented in Inner Mongolia, with the highest number of cases reported in 2019 (9 933 cases). Cases were reported throughout the year, with a peak season occurring in the winter and early spring of the following year. There were 13 538 cases in males and 11 947 cases in females, with a male-to-female ratio of 1.13:1, indicating a higher incidence rate in males. Cases were mainly concentrated in individuals under the age of 20, especially in the age group of 0 to 10 years, There were significant differences in influenza incidence rates among different regions and years, showing alternate patterns of prevalence. Retrospective spatiotemporal scanning analysis of influenza cases in Inner Mongolia Autonomous Region from 2018 to 2022 revealed that, in terms of temporal distribution, the cluster of cases mainly occurred in November to December each year and in January of the following year. During the influenza season, cases exhibited significant spatiotemporal clustering in the region. Conclusions The number of reported influenza cases in Inner Mongolia Autonomous Region varied from year to year but there was no increasing trend over time. Children under 10 years old were the primary susceptible population, and influenza exhibited significant seasonal variation and spatiotemporal clustering. It is recommended to strengthen public awareness and education on influenza prevention and vaccination before the influenza season each year, develop good hygiene habits, seek medical attention early when symptoms occur, and reduce the risk of clustered influenza outbreaks.
