Abstract:
Objective:To analyze the epidemic characteristics and changing trends of human brucellosis in Tangshan City, providing a basis for brucellosis prevention and control.Methods:Brucellosis surveillance data and historical surveillance data of Tangshan City reported from 2007 to 2022 in China Disease Prevention and Control Information System were collected. A descriptive analysis using retrospective methods was conducted to summarize the epidemic situation, distribution of three (population, time, region) and pathogenic monitoring results of brucellosis. Joinpoint regression was used to analyze the trend of brucellosis incidence.Results:From 2007 to 2022, a total of 3 949 cases of brucellosis were reported in Tangshan City, with the annual incidence ranging from 0.24 per 100 000 to 7.17 per 100 000, showing an upward trend (AAPC = 18.42%, 95% CI: 10.16% - 24.67%, P < 0.001). The affected population was mainly composed of those aged 40 - 69 years old (3 582 cases, accounting for 90.71%), male (2 957 cases, accounting for 74.88%), and farmers (3 432 cases, accounting for 86.91%). The onset time was mainly concentrated from March to August. The average annual incidence rates of brucellosis in the eastern region, western region and the central urban area were 5.31 per 100 000, 1.84 per 100 000, and 1.42 per 100 000, respectively. There were statistically significant differences among different regions (χ 2 = 1 049.17, P < 0.001). Pathogenic monitoring results revealed that 12 Brucella strains were isolated, all identified as sheep type 3. Conclusions:The incidence of brucellosis in Tangshan City is on the rise from 2007 to 2022. The incidence is mainly among middle-aged and elderly male famers, and it shows s distinct seasonal pattern. It is suggested to strengthen the prevention and control of brucellosis in the whole city.
