Abstract:
Objective:To analyze the epidemic status and characteristics of human brucellosis in Ordos City, and to provide basis for formulating perfect prevention and control countermeasures of brucellosis.Methods:The data of reported human brucellosis cases in Ordos City from 2016 to 2020 were collected through the Chinese Disease Prevention and Control Information System. Descriptive epidemiological method was used to analyze the distributions of time, region and population.Results:Totally 2 861 cases of human brucellosis were reported in Ordos City from 2016 to 2020. The average annual incidence rate was 27.68/100 000 and no deaths. The incidence rate of human brucellosis decreased year by year from 2016 to 2018 (24.11/100 000, 20.82/100 000, 20.11/100 000). But the incidence rate began to pick up in 2019 (24.59/100 000) and rose to 48.53/100 000 in 2020. The incidence peak was from March to August (1 882 cases). The cases had been reported in all over 9 banners (districts) of the city. The cumulative number of reported cases from more to less was Hangjin Banner, Dalat Banner, Otog Front Banner, Jungar Banner, Otog Banner, Dongsheng District, Wushen County, Ejin Horo Banner and Kangbashi District. The cases were predominantly male, and the sex ratio of male to female was 2.23∶1.00 (1 974 ∶ 887). The onset was mainly young and middle-aged adults, and the age was mainly 30-69 years old (2 541 cases). Farmers accounted for 65.26% (1 867 cases) in all reported cases, followed by herdsmen, accounting for 18.98% (543 cases).Conclusions:There is an obvious upward trend of human brucellosis in Ordos City in recent years, mainly among young and middle-aged male farmers. Health education for key populations should be strengthened, as well as personal protection during high-risk operations.
