Endemic status of echinococcosis in Inner Mongolia Autonomous Region from 2011 to 2017

Abstract

Abstract:

Objective To understand the endemic status and characteristics of echinococcosis in Inner Mongolia Autonomous Region from 2011 to 2017 so as to provide evidence-based information for formulating control strategies and measures. Methods Data of echinococcosis endemic in Inner Mongolia from 2011 to 2017 were collected from the China Infectious Disease Reporting Information Management System of China CDC and analyzed by using SPSS 20.0. The map of case distribution was drawn using QGIS 3.4.2. Results Totally 543 cases of echinococcosis were reported in the Region from 2011 to 2017 with 117, 89, 69, 81, 62, 62 and 63 cases reported for each year, respectively. The reported incidence decreased yearly from 0.48/100 000 in 2011 to 0.25/100 000 in 2017. A total of 25 endemic counties of echinococcosis were identified in the Region. 397 of 543 reported cases were indigenous cases in these endemic counties, accounting for 73.11%. The reported cases covered 74 counties of 12 prefectures (cities) in the whole region. The highest case incidence was reported in Xilingol and Alxa Leagues with 5.14/100 000 and 2.42/100 000, respectively. Among the 543 cases reported 255 were males and 288 females with average annual incidence of 1.97/100 000 and 2.41/100 000, respectively. The difference of incidence between males and females was statistically significant (P < 0.05). The average age of reported cases was 48 years old with highest cases reported in the 40s age group (128, 31.50%). Most cases fell into the age group from 30-59 years old, accounting for 74.03% of the total reported cases (402/543). Among the reported cases, 192 were herdsmen, 131 peasants and 111 housewives and unemployment, accounting for 35.36%, 24.13% and 20.44%, respectively. Conclusion The distribution of echinococcosis cases in Inner Mongolia Autonomous Region is sporadic, mainly in pastoral, semi-pastoral and semi-agricultural areas. Women, young and middle-aged people and herdsmen are the high-risk groups of the disease.
