为了解宁夏地区布鲁氏菌病在羊间和人间流行现状,对存栏200只羊以上规模养殖场(户)及相关从业人员开展了布鲁氏菌病流行病学和影响因素基线调查。自2008年开始到2013年,共检测羊75467只,其中阳性的有674只,总阳性率为0.89%,各年阳性率从2008年的0.71%波动上升至2013年的1.2%;2008—2013年,感染布鲁氏菌病人数亦呈递增趋势,各个年龄段均有发病,但以30~59年龄段的发病人数居多。造成人间布鲁氏菌病年龄分布差异的主要因素是人接触传染源的频繁程度、从业人员自我防护意识、防护措施等。
To understand the prevalence of brucellosis among sheep and people in Ningxia, a baseline survey on the epidemiology and influencing factors of brucellosis was conducted on over 200 sheep and above-scale farms (households) and related practitioners. From the beginning of 2008 to 2013, 75467 sheep were detected, of which 674 were positive, with a total positive rate of 0.89%. The positive rate of each year increased from 0.71% in 2008 to 1.2% in 2013; 2008-2013 Year, the number of patients infected with brucellosis also showed an increasing trend, all age groups have the incidence, but the majority of the incidence of 30 to 59 age groups. The main causes of the difference in the distribution of brucellosis among human beings are the frequency of human exposure to infectious agents, the self-protection awareness of employees and protective measures.
