Lyme disease (Borrelia burgdorferi infection) is the most common vector-transmitted disease in the United States. The majority of human Lyme disease (LD) cases occur in the summer months, but the timing of the peak occurrence varies geographically and from year to year. We calculated the beginning, peak, end, and duration of the main LD season in 12 highly endemic states from 1992 to 2007 and then examined the association between the timing of these seasonal variables and several meteorological variables. An earlier beginning to the LD season was positively associated with higher cumulative growing degree days through Week 20, lower cumulative precipitation, a lower saturation deficit, and proximity to the Atlantic coast. The timing of the peak and duration of the LD season were also associated with cumulative growing degree days, saturation deficit, and cumulative precipitation, but no meteorological predictors adequately explained the timing of the end of the LD season.
莱姆病（伯氏疏螺旋体感染）是美国最常见的虫媒传染病。大多数人类莱姆病（LD）病例发生在夏季，但高峰期的出现时间因地理位置和年份而异。我们计算了 1992 年至 2007 年 12 个高度流行地区的主要 LD 季节的开始、高峰、结束和持续时间，然后检查了这些季节性变量的时间与几种气象变量之间的关联。LD 季节的开始时间越早，第 20 周之前的累积生长度日越高，累积降水量越低，饱和度缺陷越低，与大西洋海岸越近。LD 季节的高峰期和持续时间也与累积生长度日、饱和度缺陷和累积降水量有关，但没有气象预测因子能够充分解释 LD 季节结束的时间。
