Epidemiology and awareness of brucellosis in populations at high risk in Hulunbuir, Inner Mongolia Autonomous Region, 2010–2019

Abstract

Objective To analyze the surveillance results of brucellosis in high-risk population in Hulunbuir, Inner Mongolia Autonomous Region from 2010 to 2019 and provide evidence for adjusting the brucellosis prevention and control strategy. Methods The stratified sampling surveillance in populations with direct exposures to livestock and its products was conducted in counties of Hulunbuir. Blood samples were taken from the individuals in these counties for preliminary screening by using rose bengal plate agglutination test (RBPT) and for confirmation by using serum agglutination test (SAT). The survey of brucellosis related knowledge awareness was carried out in the above-mentioned populations. The questionnaire included three parts: basic knowledge about brucellosis, risk factors and brucellosis prevention knowledge. Descriptive statistics were used to analyze the infection, incidence and knowledge of brucellosis among high-risk populations. The rate and composition ratio were compared with χ2 test, and P Results From 2010 to 2019, a total of 162 539 blood samples were tested in Hulunbuir, in which 8 556 were positive (5.26%). Over time, the positive rate of blood test showed a downward trend. The difference was significant ( χ2=448.824, P Conclusion The prevention and control strategy for human brucellosis in Hulunbuir has achieved certain progress, but the situation is still serious. Therefore, it is necessary to carry out continuous surveillance for human brucellosis and conduct health education in populations at high risk.
