On October 15, 1996, a physician notified the Illinois Department of Public Health about five patients with an unknown febrile illness who had returned from a white-water rafting trip on flooded rivers in Costa Rica during September 27-28, 1996. The five patients had been members of a white-water rafting expedition involving 26 rafters from five states, the District of Columbia, and Costa Rica. This report summarizes the findings of the multistate investigation conducted by the Illinois Department of Public Health and by CDC in collaboration with the Ministry of Health of Costa Rica. The findings implicated leptospirosis as the cause of disease and contaminated river water as the probable source of illness.
1996年10月15日，一名医生向伊利诺伊州公共卫生部通报了5名患有不明发热疾病的患者，这些患者于1996年9月27日至28日在哥斯达黎加洪水泛滥的河流上进行了一次白水漂流旅行后归来。这5名患者是一次白水漂流探险队的成员，该探险队有来自5个州、哥伦比亚特区和哥斯达黎加的26名漂流者。本报告总结了伊利诺伊州公共卫生部和疾病控制与预防中心（CDC）与哥斯达黎加卫生部合作进行的多州调查结果。调查结果表明钩端螺旋体病是病因，受污染的河水可能是疾病来源。
