Abstract:
Objective:To learn about the incidence of brucellosis in China from 2003 to 2024 and its ranking changes in the national notifiable Class A and B infectious disease reports, providing theoretical basis for improving brucellosis prevention and control strategies.Methods:Using retrospective analysis method, data on notifiable Class A and B infectious disease reports from 2003 to 2024 were collected from the official websites of the National Health Commission and the National Bureau of Statistics, along with annual national population data. The number of brucellosis cases in each year was counted, the incidence rate was calculated, and its ranking in the annual notifiable Class A and B infectious disease reports was determined to analyze ranking changes.Results:From 2003 to 2024, the annual reported cases of brucellosis in China were 6 448, 11 472, 18 416, 19 013, 19 721, 27 767, 35 816, 33 772, 38 151, 39 515, 43 486, 57 222, 56 989, 47 139, 38 554, 37 947, 44 036, 47 245, 69 767, 71 437, 70 439, and 67 418 cases, respectively. Among them, the lowest incidence rate in 2003 was lowest (0.50/100 000, national population: 1 292.27 million), and the incidence rate in 2022 was highest (5.06/100 000, national population: 1 411.75 million). The incidence rate in 2022 was 10.12 times that in 2003. From 2003 to 2024, the brucellosis incidence rate increased year by year (χ 2trend = 21 483.18, P < 0.001). From 2003 to 2005, the annual reported cases of brucellosis did not rank in the top 10 in notifiable Class A and B infectious disease reports, ranking 12th, 17th, and 16th, respectively. From 2006 to 2024, it consistently ranked in the top 10, with the lowest rankings in 2006 and 2007 at 10th place, and the highest rankings in 2021 and 2023 at 5th place; In 2024, it ranked 6th place. Conclusions:From 2003 to 2024, the incidence rates in China have showed an increasing trend, with its ranking in notifiable Class A and B infectious disease reports gradually rises from 12th in 2003 to 6th in 2024. Healthcare professionals need to continue to pay attention to the clinical diagnosis, treatment, and disease prevention and control of brucellosis.
