In recent years, the reported incidence of human brucellosis has been increasing year by year, and the epidemic range has been spread continuously. It has gradually spread from animal husbandry areas with high incidence to world wide, and become an important public health problem in China. Research on the epidemiological characteristics of brucellosis is of great significance for the effective prevention and control of brucellosis epidemic. This paper systematically reviews brucellosis at home and abroad, especially the domestic epidemic situation and hotspots of brucellosis, understands the incidence situation in various regions, and analyzes the causes of brucellosis based on literature research, so as to provide a theoretical basis for the early warning, monitoring, as well as adjustment of prevention and control policy of brucellosis.
