Lyme disease (LD) is caused by the tickborne spirochete Borrelia burgdorferi sensu lato and is the most common vectorborne disease in the United States. Surveillance for LD was initiated by CDC in 1982, and the Council of State and Territorial Epidemiologists designated it a nationally notifiable disease in January 1991. For surveillance purposes, LD is defined as the presence of an erythema migrans rash > or =5 cm in diameter or laboratory confirmation of infection with evidence of at least one manifestation of musculoskeletal, neurologic, or cardiovascular disease (1). This report summarizes the provisional number of cases of LD reported to CDC during 1996 and indicates that the number of cases reported to CDC was a record high.
莱姆病（LD）由蜱传播的疏螺旋体伯氏疏螺旋体复合群引起，是美国最常见的媒介传播疾病。美国疾病控制与预防中心（CDC）于1982年开始对莱姆病进行监测，1991年1月，州和地区流行病学家委员会将其指定为全国法定报告疾病。出于监测目的，莱姆病的定义为出现直径大于或等于5厘米的游走性红斑皮疹，或实验室确诊感染且有肌肉骨骼、神经或心血管疾病至少一种表现的证据（1）。本报告总结了1996年向CDC报告的莱姆病病例临时数量，并表明向CDC报告的病例数创历史新高。
