Swimmer's itch, or cercarial dermatitis, is a waterborne non-communicable skin condition caused by schistosome cercariae released by aquatic snails. Cercarial dermatitis appears worldwide, but may be caused by different trematode species. The itchy maculopapular rash develops on exposed areas of the skin and typically resolves within 1-3 weeks. Shedding of infective larvae from snails is temperature dependent, and high temperatures and sunshine increase the risk of encountering the parasite and becoming infected. The unusually warm spring and summer of 2018 led to an increasing number of reports of the condition in Denmark and established a collaboration between the Department of Dermatology and the Faculty of Health and Medical Sciences, Department of Veterinary and Animal Sciences. This study explored the clinical picture of the disease, and demonstrated the occurrence of infected fresh water snail species in selected Danish water bodies. In conclusion, a risk of swimmer's itch in Denmark was confirmed.
游泳者痒疹,或尾蚴性皮炎,是一种由水生蜗牛释放的血吸虫尾蚴引起的、经水传播的非传染性皮肤疾病。尾蚴性皮炎在全球范围内都有出现,但可能由不同的吸虫物种引起。瘙痒的斑丘疹出现在皮肤暴露部位,通常在 1-3 周内消退。从蜗牛身上脱落的感染性幼虫取决于温度,高温和阳光会增加遇到寄生虫和感染的风险。2018 年异常温暖的春季和夏季导致丹麦报告的此类病例数量不断增加,并促成了丹麦皮肤病学系与健康与医学科学系、兽医与动物科学系之间的合作。本研究探讨了该疾病的临床特征,并证明了在丹麦选定的水体中存在感染性淡水蜗牛物种。总之,丹麦存在游泳者痒疹的风险。
