Abstract:
Objective:To investigate the epidemic characteristics of human brucellosis and the awareness of brucellosis prevention and control knowledge among occupational populations in Xuzhou City, Jiangsu Province.Methods:The data of brucellosis cases reported from January to December 2023 in the China Disease Prevention and Control Information System's Infectious Disease Surveillance System where the current residence was Xuzhou City, were collected. The epidemiological distribution characteristics across the three dimensions (time, region, and population) were analyzed, and the etiological characteristics of Brucella strains collected from sentinel hospitals in Xuzhou City during the same period were analyzed. Meanwhile, in September 2023, a survey was conducted on the awareness of brucellosis prevention and control knowledge among occupational populations in 7 counties (cities, districts) with a high incidence of brucellosis in Xuzhou City. Binary logistic regression was used to analyze the influencing factors. Results:In 2023, a total of 124 human brucellosis cases were reported in Xuzhou City, with an annual incidence rate of 1.37/100 000. Brucellosis occurred in all months of the year, with a peak incidence from May to August, accounting for 46.77% (58/124). The incidence rate of brucellosis in Feng County, Pei County, Suining County, Xinyi City and Pizhou City (1.86/100 000) was higher than that in Gulou District, Yunlong District, Quanshan District, Jiawang District and Tongshan District (0.71/100 000), with a statistically significant difference (χ 2 = 19.15, P < 0.001). Among 124 cases of brucellosis, 81 cases (65.32%) were males and 43 cases (34.68%) were females. The incidence rate of brucellosis in males (1.78/100 000) was higher than that in females (0.96/100 000), with a statistically significant difference (χ 2 = 11.08, P < 0.001). The 55 - 64 age group reported a relatively higher number of cases (45 cases, 36.29%), with an incidence rate of 3.97/100 000. The main occupation was farmers (85 cases, 68.55%). In 2023, a total of 9 strains of Brucella were collected from the sentinel hospitals in Xuzhou City, all of which were Brucella melitensis, mainly classified as biotype 3 (7/9). In 2023, a total of 984 occupational population with brucellosis were surveyed in Xuzhou City, and the overall awareness rate of brucellosis prevention and control knowledge was 3.25% (32/984). By binary logistic regression analysis, the awareness rates of brucellosis prevention and control knowledge among veterinarians and those with high school or vocational school education, college education or above were relatively high [ OR (95% CI): 21.24 (1.52 - 297.74), 13.32 (3.48 - 50.96), 18.90 (3.68 - 97.13), P < 0.05]. Conclusions:In 2023, the incidence rate of human brucellosis in Xuzhou City is at a relatively high level, with men, middle-aged and elderly people, and farmers as the main population. The awareness rate of brucellosis prevention and control knowledge among occupational population is relatively low, and it is necessary to strengthen publicity, education, and behavioral intervention.
