Abstract:
Objective:To study the epidemiological characteristics and clinical diagnosis of human brucellosis in Qujing City, Yunnan Province.Methods:Through the Infectious Disease Reporting Information Management System of the China Disease Prevention and Control Information System, the basic information and clinical diagnostic data of brucellosis cases reported in Qujing City from January 2008 to December 2023 were retrospectively collected. Descriptive epidemiological methods were used to analyze the epidemic profile, three distribution characteristics (time, population, region), and diagnosis of brucellosis.Results:A total of 1 417 brucellosis cases were reported in Qujing City from 2008 to 2023, with no death. The annual average incidence of brucellosis was 1.49/100 000, with no cases reported in 2009 and 2010, and the highest incidence in 2023 (7.82/100 000). The incidence of brucellosis showed an increasing trend year by year (χ 2trend = 1 874.58, P < 0.001). The number of cases from June to November accounted for 61.54% (872/1 417). The majority of brucellosis cases were in the age group of 36 - 65 years old, accounting for 67.82% (961/1 417). Among them, there were 954 males and 463 females, with a gender ratio of 2.06 ∶ 1.00. Farmers were the main occupation, accounting for 84.33% (1 195/1 417). The cases were mainly distributed in Luliang County (621 cases), Xuanwei City (282 cases) and Shizong County (137 cases), accounting for 73.39% (1 040/1 417). The median interval between onset and diagnosis was 13 days, and the cases with intervals ≤7 d, 8 - 30 d, and ≥31 d accounted for 32.11% (455/1 417), 40.16% (569/1 417), and 27.73% (393/1 417), respectively. Totally 63.94% (906/1 417) of the cases were confirmed in medical institutions in Qujing City. Conclusions:The incidence of brucellosis in Qujing City is increasing year by year, with men, middle-aged and elderly people and farmers as the main population, summer and autumn as the peak period, and Luliang County, Xuanwei City and Shizong County as the high incidence areas. Most cases have an interval of less than 30 days between onset and diagnosis, and can be diagnosed within the jurisdiction.
