Trichinella nativa infection (trichinellosis) is highly prevalent in Arctic wildlife, but the human burden of trichinellosis in present-day Greenland is unknown. The study aimed to determine Trichinella seroprevalence in an eastern Greenlandic hunting community and to evaluate risk factors for seropositivity. Overall, 998 inhabitants aged 10 years in the Ammassalik municipality were tested for Trichinella-specific IgG antibodies. Background information was obtained from questionnaires. Seropositivity was 1.4% in persons aged <40 years and increased to >12% in those aged 60 years. Older age, occupation as hunter or fisherman, and consumption of polar bear meat significantly increased the risk of Trichinella seropositivity. The seropositivity age pattern probably reflects changes in dietary preferences, but could also reflect mandatory meat inspection since 1966. However, preventive measures against Trichinella infection should be strengthened in Greenland.
本地感染旋毛虫病（旋毛虫病）在北极野生动物中非常普遍，但目前格陵兰岛的旋毛虫病的人类负担尚不清楚。该研究旨在确定东部格陵兰狩猎社区的旋毛虫血清流行率，并评估血清阳性的危险因素。总体而言，对 Ammassalik 市 10 岁及以上的 998 名居民进行了旋毛虫特异性 IgG 抗体检测。背景信息来自问卷调查。<40 岁人群的血清阳性率为 1.4%，而 60 岁人群的血清阳性率增加到>12%。年龄较大、职业为猎人或渔民以及食用北极熊肉会显著增加旋毛虫血清阳性的风险。血清阳性的年龄模式可能反映了饮食偏好的变化，但也可能反映了自 1966 年以来强制性的肉类检查。然而，格陵兰岛应加强针对旋毛虫感染的预防措施。
