ABSTRACT
Objective:
To investigate the epidemic characteristics of human brucellosis in Inner Mongolia Autonomous Region from 2018 to 2020, and provide a reliable scientific basis for formulating brucellosis prevention and control strategies in Inner Mongolia Autonomous Region.Methods:
A retrospective study was carried out to collect data of human brucellosis in Inner Mongolia Autonomous Region from 2018 to 2020 from the "China Disease Control and Prevention Information System", and the monitoring data and information of confirmed cases were collected from the annual summary data reported by the leagues (cities) of the Inner Mongolia Autonomous Region. Using descriptive epidemiological methods, the epidemic situation, three distributions (time, region and population distributions) of brucellosis, and the serological and pathogenic test results of active monitoring population were analyzed.Results:
From 2018 to 2020, a total of 40 665 cases of brucellosis were reported in Inner Mongolia Autonomous Region, with an annual average incidence rate of 53.47/100 000. The number of annual incidence had increased from 10 111 in 2018 to 16 406 in 2020, and the annual incidence rate had increased from 39.99/100 000 in 2018 to 64.60/100 000 in 2020. The spring and summer was the peak incidence, mainly in March to August, accounting for 64.90% (26 390/40 665) . There were reports of brucellosis cases in 12 leagues (cities) of Inner Mongolia Autonomous Region, and the top 3 regions with the number of reported cases were Tongliao City (9 896 cases), Xing'an League (6 136 cases) and Chifeng City (4 934 cases). The age of onset of brucellosis cases was mainly 30 - < 65 years old(33 539 cases), and the sex ratio between men and women was 2.18 ∶ 1.00 (27 890 ∶ 12 775); the occupational distribution was mainly farmers, accounting for 79.23% (32 221/40 665). From 2018 to 2020, 704 085 people were actively monitored in the region, of which 391 941 were serologically tested, and the infection rate was 4.57% (17 920/391 941); and there were 9 539 new cases in the active monitoring population. In 3 years, 19 strains of Brucella sheep type 3 and 11 strains of Brucella sheep type 1 were isolated.Conclusions:
From 2018 to 2020, the incidence rate of brucellosis in Inner Mongolia Autonomous Region is increasing year by year. There are many new cases in the active monitoring population, and more underreporting cases. It is recommended to expand the scope of monitoring, strengthen pathogen monitoring among humans and animals, and joint prevention and control of various departments to improve the self-protection awareness of the masses.
