ABSTRACT
Objective To investigate the first human brucellosis outbreak in Fujian Province,aiming to identify the source,risk factors of infection,and recommend control measures.Methods Epidemiological investigation was conducted by combining with agricultural sector on human and animal in the incident area of Zhangzhou City of Fujian Province.Respondents included 17 professionals from the outbreak sheep farm,as well as 9 ones from four nearest farms (including 2 pig farms,1 sheep farm and 1 cow farm) in directions of eastern,southern,western and northern.Then information of cognitive level and daily protection on brucellosis among pasture breeding staffs through case studies were got,serum of pasture breeding staffs and animals was collected (including 262 from the outbreak sheep farm and 50 from another sheep farm which nearly 5 kilometres away) to detect brucellosis antibody,and sheep sources were investigated simultaneously.Results A total of 26 people were detected,the infection rate was 26.9% (17 people,in the epidemic area),the other four farming units without brucellosis infection.In epidemic focus,seven human infections (5 confirmed cases,2 asymptomatic infected) were identified,with an infection rate 41.2% (7/17) and the brucellosis antibody positive rate among sheep was 46.2% (121/262),while no positive sheep in the nearest sheep farm (0/50).Both unprotected lamb handling and stillbirth treatment got a 100.0% infection rate.Among the investigated professional staffs,92.3% (24/26) had no awareness of clinical symptoms and signs of brucellosis,while 11.5% (3/26) took protective measures when working.Conclusions Unquarantined sheep is the infection source of this brucellosis outbreak,unprotected lamb handling and stillbirth treatment are the main route of transmission.High sheep infection rate,lack of brucellosis awareness,precaution missing among pasture breeding staffs and animal quarantine are all contributing to this outbreak.
