The epidemiologic polls concerning 166 cases of brucellosis are retrospectively analyzed; the cases are registered by the Preventive Medicine Service of Miguel Servet Hospital for five years (1980-1985). Most of our cases are of recent evolution, although 55% began to give symptoms more of 2 weeks ago and 30% more of 1 month ago. A clear annual increase of the number of cases, fundamentally of the male sex and patients coming from the rural areas, is observed. The percentage of cases in men (73.5%) is almost three times as those in women (26.5%), and the most numerous groups are the 20-29 interval age group and olders above 60. There is a small percentage of people with a professional risk factor (30.1%), which rise, slightly, for the ones who told of contact with cattle (39.2%) and rose up to 53.6% for the ones who consumed non controlled dairy products. However, in 23% of men and 40.9% of women the existence of some risk factors was unknown.
对166例布鲁氏菌病病例的流行病学调查进行回顾性分析；这些病例由米格尔·塞尔维特医院预防医学服务部门登记了五年（1980 - 1985年）。我们的大多数病例为近期发病，尽管55%的病例在两周多前开始出现症状，30%的病例在一个多月前开始出现症状。观察到病例数量呈明显的年度增长，主要是男性病例以及来自农村地区的患者。男性病例的百分比（73.5%）几乎是女性病例百分比（26.5%）的三倍，人数最多的群体是20 - 29岁年龄组和60岁以上的老年人。有职业危险因素的人群比例较小（30.1%），对于那些自述与牛接触的人这一比例略有上升（39.2%），而对于那些食用未受管控乳制品的人这一比例上升至53.6%。然而，23%的男性和40.9%的女性存在某些危险因素的情况不明。
