In May-November 1977 erythema chronicum migrans of Lyme arthritis occurred in at least 12 children in New London County, Connecticut, east of the original 3-town epidemic focus. The attack rate (0.15 cases per 1,000 persons under 18) was considerably lower than within the focus itself but similar to the rate in towns west of the focus. No cases were identified in Litchfield County in northwest Connecticut. Observed rates of Lyme disease varied markedly within Connecticut in 1977.
1977年5月至11月期间，莱姆关节炎的慢性游走性红斑在康涅狄格州新伦敦县至少12名儿童中出现，该县位于最初3个城镇的疫情集中地以东。发病率（每1000名18岁以下人群中有0.15例）明显低于疫情集中地内部，但与集中地以西城镇的发病率相似。在康涅狄格州西北部的利奇菲尔德县未发现病例。1977年，莱姆病的观察发病率在康涅狄格州内差异显著。
