In 1982, national surveillance for Lyme disease was established by the Centers for Disease Control to monitor trends and determine endemic geographic areas. Initially, the endemic areas corresponded to the known distribution of Ixodes dammini, a five-state area of the northeastern seaboard (New York, New Jersey, Connecticut, Rhode Island, and Massachusetts) and Wisconsin and Minnesota. Increasing numbers of cases have been reported outside these areas, however, 86% of the provisional 5731 cases reported to CDC were acquired in these seven states. The number of reported cases increased from 491 in 1982 to approximately 1500 per year in 1984-1986, making Lyme disease the most commonly reported tick-borne illness in the United States. The apparently widening distribution of Lyme disease indicates that physicians in all regions of the country should be familiar with its signs and symptoms. Investigations of the vector in areas endemic for Lyme disease where Ixodes ticks are not found are warranted.
1982年，疾病控制中心建立了莱姆病国家监测系统，以监测发病趋势并确定疾病流行的地理区域。最初，疾病流行区域与达氏硬蜱已知的分布范围相对应，即东北部沿海的五个州（纽约、新泽西、康涅狄格、罗德岛和马萨诸塞）以及威斯康星州和明尼苏达州。然而，在这些区域之外报告的病例数量不断增加，向疾病控制中心报告的5731例临时病例中，86%是在这七个州感染的。报告病例数从1982年的491例增加到1984 - 1986年的每年约1500例，使莱姆病成为美国报告最多的蜱传疾病。莱姆病明显扩大的分布范围表明，美国所有地区的医生都应熟悉其体征和症状。对于未发现硬蜱的莱姆病流行地区的病媒进行调查是必要的。
