In Aragon, official veterinary controls to detect the presence of Trichinella in meat products have allowed trichinosis to be a low-incidence disease in the form of outbreaks associated with family consumption of meat products that are not sanitarily controlled. The aim of the work was to describe the epidemiological characteristics of the trichinosis outbreaks that occurred in Aragon during the study period and the action measures carried out, which served as a basis for redesigning and strengthening prevention and control measures.
Descriptive study of the characteristics of time, place, person, food implicated, etiological agent and control measures implemented in the outbreaks identified by the Epidemiological Surveillance Network of Aragón from 01/01/1998 to 31/12/2017. For the descriptive analysis, the mean with its standard deviation and proportions were calculated.
During the study period (from 01/01/1998 until 31/12/2017) there were 7 family outbreaks with 294 exposed, 103 cases (Attack Rate 35%), of which 29 were hospitalized (28.1%). The case fatality rate was 1%. The average age of the cases was 43.3 years (standard deviation 15.9). 70.8% of the cases were male. Outbreaks were concentrated between December and May. Five outbreaks originated after consumption of wild boar. The etiological agent identified in meat and/or biological samples from the cases was Trichinella spiralis in four outbreaks and Trichinella britovi in two other outbreaks, while the agent could not be identified in one outbreak. In all outbreaks, actions were carried out in accordance with the recommendations established by the National Epidemiological Surveillance Network (RENAVE).
Trichinosis in Aragon takes the form of sporadic family outbreaks coinciding with the time of wild boar hunting and home slaughtering of pigs and is associated with the consumption of meat products not controlled sanitarily, so it is necessary to strengthen health education and intersectoral collaboration in the development and implementation of prevention and control strategies.
在阿拉贡，官方兽医检测肉制品中旋毛虫存在的控制措施使得旋毛虫病以与家庭食用未经卫生控制的肉制品相关的暴发形式成为一种低发疾病。这项工作的目的是描述研究期间阿拉贡发生的旋毛虫病暴发的流行病学特征以及所采取的行动措施，这些措施为重新设计和加强预防与控制措施奠定了基础。
对阿拉贡流行病学监测网络在1998年1月1日至2017年12月31日期间确定的暴发中的时间、地点、人员、涉及食物、病原体和实施的控制措施的特征进行描述性研究。对于描述性分析，计算了均值及其标准差和比例。
在研究期间（从1998年1月1日至2017年12月31日），有7起家庭暴发，294人暴露，103例病例（罹患率35%），其中29例住院（28.1%）。病死率为1%。病例的平均年龄为43.3岁（标准差15.9）。70.8%的病例为男性。暴发集中在12月至5月。5起暴发源于食用野猪。在病例的肉类和/或生物样本中鉴定出的病原体，4起暴发为旋毛形线虫，另外2起暴发为布氏旋毛虫，而1起暴发中未鉴定出病原体。在所有暴发中，均按照国家流行病学监测网络（RENAVE）制定的建议采取了行动。
阿拉贡的旋毛虫病表现为与野猪狩猎和家庭杀猪时间一致的散发性家庭暴发，并且与未经卫生控制的肉制品消费有关联, 因此有必要在制定和实施预防与控制策略时加强健康教育和部门间合作。
