为认清布鲁氏菌病 (布病 )疫情回升的原因、疫情发展趋势和人群不同生理状态与布病发病的关系 ,我们对 1990～ 1996年辽宁省的布病疫情调查资料进行了分析。结果 :疫情回升的主要原因是引进小尾寒羊 ,疫情以散点状多发疫点形式分布 ,多数疫点扩大 ,铁岭、抚顺 2个市已呈明显融合成 2个市范围的大片疫区的趋势 ;布病危害的人群主要是农区养羊户家庭人口 ,怀孕导致人体对布氏菌易感性增高 ,接触同样病畜污染环境的城乡人口发病率有显著性差异。
In order to find out the cause of brucellosis (brucellosis), the epidemic development trend and the relationship between different physiological states and the incidence of brucellosis, we analyzed the survey data of brucellosis in Liaoning Province from 1990 to 1996. Results: The main reason for the rebound was the introduction of small-tailed Han sheep. The outbreaks were distributed in the form of scattered multi-point outbreaks and the majority of outbreaks were expanded. The two cities of Tieling and Fushun showed a trend of becoming merged into large epidemic areas in two cities ; The main cause of brucellosis is the population of sheep-raising households in rural areas. Pregnancy causes the human body to have an increased susceptibility to brucellosis, and there is a significant difference in the incidence of urban and rural population exposed to the same sick animal as the polluted environment.
