Abstract

Background: Brucellosis, which is a zoonosis, is able to gravely infringe public health. This research work aims at presetting the epidemic of human brucellosis in Jiangsu from the year of 2006 to the year 2016, in addition to providing the proof of avoiding from brucellosis in endemic regions.
