Lyme disease (LD) is caused by the tickborne spirochete Borrelia burgdorferi sensu lato. Surveillance for LD was initiated by CDC in 1982 and, during 1990, the Council of State and Territorial Epidemiologists designated LD as a nationally notifiable disease. 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 objective evidence of musculoskeletal, neurologic, or cardiovascular disease. This report summarizes cases of LD reported by state health departments to CDC during 1995 and indicates that the number of reported cases declined slightly from 1994.
莱姆病（LD）由蜱传播的伯氏疏螺旋体狭义种引起。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，1990年，州和地区流行病学家理事会将莱姆病指定为全国法定报告疾病。出于监测目的，莱姆病定义为出现直径大于或等于5厘米的游走性红斑皮疹，或实验室确认感染且有肌肉骨骼、神经或心血管疾病的客观证据。本报告总结了1995年各州卫生部门向CDC报告的莱姆病病例，并表明报告病例数较1994年略有下降。
