The species, , causes human paragonimiasis in North America. As a foodborne disease, human infection with occurs after eating raw or undercooked crayfish containing metacercariae. Many risk factors have been described in the literature, including young adult age, male, alcohol consumption, outdoor activities involving rivers within Missouri, and ingesting raw or partially cooked crayfish. Here, we report a case of a 41-year-old male with a 5-year history of cough who presented with acute shortness of breath. Further workup showed mild eosinophilia and spontaneous pneumothorax. A definitive diagnosis was made with a lung biopsy, which showed eggs. Further questioning revealed that the patient took a hunting and river rafting trip on a river in Missouri 5 years ago, though the history was negative for any crayfish consumption. Paragonimiasis should be considered in those with associated clinical features, including cough and eosinophilia, with a history of a river raft float trip in Missouri, even if the history is negative for crayfish ingestion or travel.
该物种， ，在北美导致人类肺吸虫病。作为一种食源性疾病，人类感染 是在食用含有后尾蚴的生的或未煮熟的小龙虾之后发生。文献中描述了许多风险因素，包括青壮年、男性、饮酒、在密苏里州境内涉及河流的户外活动以及食用生的或部分煮熟的小龙虾。在此，我们报告一例41岁男性病例，该患者有5年咳嗽病史，此次因急性呼吸急促就诊。进一步检查显示轻度嗜酸性粒细胞增多和自发性气胸。通过肺活检做出了明确诊断，活检显示有 虫卵。进一步询问发现，患者5年前在密苏里州的一条河流上进行了一次狩猎和漂流旅行，尽管其食用小龙虾的病史为阴性。对于有相关临床特征（包括咳嗽和嗜酸性粒细胞增多）且有在密苏里州进行河流漂流旅行史的患者，即使其小龙虾摄入或旅行史为阴性，也应考虑肺吸虫病。
