Infection caused by the lung fluke is endemic in north eastern parts of India. Paragonimus westermani and Paragonimus heterotremus are known to be endemic in eastern Indian states of Manipur and Nagaland. The infection is related to eating habits of the locals and is acquired by ingestion of raw, inadequately cooked crabs or crayfish containing encysted metacercariae which act as second intermediate hosts during the life cycle of the lung fluke. Diagnosis is generally delayed due to lack of suspicion and presentation similar to tuberculosis which is endemic in the population. We report pleuropulmonary paragonimiasis in a soldier from eastern India who presented with chest pain, haemoptysis, and eosinophilia. He gave history of consumption of raw crabs while on leave at his native village in Nagaland. Ova morphologically resembling Paragonimus heterotremus were detected in sputum and bronchoalveolar lavage specimen. Symptoms resolved with praziquantel treatment.
肺吸虫感染在印度东北部地区流行。曼尼普尔邦和那加兰邦等印度东部邦存在并殖吸虫病，曼氏并殖吸虫和卫氏并殖吸虫为其病原体。感染与当地人的饮食习惯有关，通过摄入含有囊蚴的生的或未充分煮熟的螃蟹或小龙虾而获得，囊蚴在肺吸虫的生活史中充当第二中间宿主。由于缺乏怀疑和表现类似于该人群中流行的肺结核，因此通常会延迟诊断。我们报告了一名来自印度东部的士兵患有胸膜肺并殖吸虫病，其表现为胸痛、咯血和嗜酸性粒细胞增多。他在那加兰邦的家乡休假时曾食用生螃蟹。在痰液和支气管肺泡灌洗液标本中检测到形态上类似于卫氏并殖吸虫的卵。吡喹酮治疗后症状缓解。
