Objective To understand the epidemiological characteristics of human brucellosis in Xinjiang, and provide scientific basis for the development of the prevention and control strategies of human brucellosis in the future.
Methods The epidemiological characteristics of brucellosis cases reported in Xinjiang from 2016 to 2020 were analyzed by using descriptive methods.
Results From 2016 to 2010, a total of 23 045 brucellosis cases were reported in 14 prefectures in Xinjiang, mainly distributed in Yili, Changji, Tcheng and Aksu, accounting for 59.12% (13 625 cases) of the total cases. The number of reported cases showed a decreasing trend year by year, and the incidence rate decreased from 31.14/100 000 in 2016 to 10.19/100 000 in 2020. The annual incidence peak of brucellosis was during May–August, and cases were reported in all age groups, the youngest one was 1 month, the oldest one was 94 years old, the average age of the cases was 41 years , and the most cases were aged 30–50 years (66.70%). In the reported cases, there were 16 347 males and 6698 females with a gender ratio of 2.44∶1. The cases in farmers and herdsmen accounted for 68.90%.
Conclusion The reported case number and incidence rate of brucellosis in Xinjiang decreased year by year, but the reported cases were widely distributed. It is suggested to strengthen the joint prevention and control of multiple departments and fully implement relevant prevention and control measures.
