Abstract

Abstract:

In order to investigate the trend in echinococcosis in Inner Mongolia from 2015 to 2023, all data pertaining to echinococcosis patients in Inner Mongolia from 2015 to 2023 were captured from the National Notifiable Disease Reporting System, and temporal, spatial and human distributions of echinococcosis were analyzed with a descriptive epidemiological method. A total of 500 echinococcosis cases were reported in 12 cities (leagues) of Inner Mongolia from 2015 to 2023. Echinococcosis cases were reported every year during the study period, with the highest number of cases reported in 2018 (104 cases, 21.0% of all cases), and the number of echinococcosis cases decreased significantly since 2021. In terms of regional distribution, Xilingol League (202 cases, 40.4% of all cases), Chifeng City (144 cases, 28.8%), and Hulun Buir City (52 cases, 10.4%) had the highest number of reported echinococcosis cases. There were 255 male echinococcosis cases and 245 female cases, with a male-to-female ratio of 1 ∶ 0.96, and the main occupations included herders (151 cases, 30.0%), farmers (145 cases, 29.0%), and housewives and unemployed (104 cases, 21.0%). The reported echinococcosis cases had ages of 5 to 97 years, and were concentrated at ages of 30 to 69 years, with the highest number of cases at 50 to 59 years (127 cases, 25.4%), followed by at ages of 40 to 49 years (116 cases, 23.2%). These data demonstrate that the number of reported echinococcosis cases peaked in Inner Mongolia in 2018 and decreased rapidly since 2021, indicating satisfactory effectiveness of the comprehensive echinococcosis control programme. Intensified management of the source of Echinococcus infections, surveillance on human echinococcosis and health education are recommended.
