Spatial and Temporal Distribution Changes of Human Brucellosis in Inner Mongolia, China, effects of Husbandry and Control Measures

Abstract BackgroundInner Mongolia has the highest incidence rate, causing great public health and economic losses. A number of policies to guide the prevention and control of human brucellosis had been issued and have made some achievements. Analysis of the distribution characteristics and changes of human brucellosis is important for the targeted prevention and control of this disease.MethodsWe collected various policies and measures related to brucellosis promulgated, and comprehensively analyzed the spatial and temporal distribution of human brucellosis in Inner Mongolia from 2005 to 2019 using the Bayesian theory of space-time modeling. ResultsWith the implementation of various policies and measures, great achievements have been made and distribution trends changed. Some western regions have changed into stable or cold-spot counties, and most cities in the eastern region have become hot-spot counties during the time period. The rising trend of risk in three cities is slowing down, while the risk in two cities is growing faster than the overall trend.ConclusionThe effective prevention and control measures are essential. The analysis results of this study may provide a theoretical and scientific basis for the public health department to develop targeted effective prevention and control measures for human brucellosis.
