Abstract：Objective In order to find out the cause of brucellosis,clarify the epidemic scope,and provide a scientific basis for the prevention of similar outbreaks in the future.Methods Case search was carried out through case investigation,hospital treatment system inquiry,key population screening and other means.Brucella infection preliminary screening and confirmation experiments were carried out on the investigation subjects,and brucella fluorescence quantitative PCR detection was carried out on environmental samples.The results were described and analyzed.Results A total of 8 confirmed cases of brucellosis and 1 recessive infected case have been reported.All 10 environmental samples were positive for brucella,and all of them were Brucella sheep.The infection rate of those exposed to the environment after blowing lambs(9/12)was higher than that of those who left before blowing lambs(0/6),and the difference was statistically significant(χ2 = 6.25,P＜0.05).Conclusion Exposure to the environment after blowing lambs is a risk factor for brucellosis infection,and respiratory transmission is one of the transmission routes in this outbreak.
