Duration of Tick Bites in a Lyme Disease-endemic Area

摘要: Regression equations, based on scutal index (body length/scutal width), were developed to determine the duration of attachment for nymphal and adult female Ixodes scapularis ticks. Feeding times calculated 444 300 ticks submitted by bite victims between 1985 1989 in Westchester County, New York, an area where Lyme disease is highly endemic. Nymphs attached a mean 34.7 hours, with 26.8% removed after 48 critical time transmission Borrelia burgdorferi. Attachment increased victim age class (Kruskal-Wallis test, p < 0.05). Mean (28.7 hours) was significantly less 0.05) than that nymphs, 23.3% more hours. The 0- 9-year had highest proportion (37.1%) females remain tick-bite longer they children. However, children have high risk acquiring because receive bites also are likely prevent transmission.
