But cooler weather doesn't mean that folks heading into long grass and forests are out of the woods yet. The blacklegged ticks that carry borrelia burgdorferi, the virus that causes Lyme disease, can remain active as long as temperatures are above freezing.
How do people react after a tick bite, and what state of mind can physicians expect in patients calling or coming into the office? An informal video survey of dog walkers, gardeners and, yes, even a shepherd at the Rock Meadow conservation area in Belmont, Massachusetts, suggests there's a healthy range of “Lyme literacy" among the outdoor set.
Most people said they would contact their primary care physician after a tick encounter, and most would expect to receive antibiotics. (Be forewarned: Parents of children with suspected tick bites can sometimes be overzealous in requesting antibiotics for their offspring, even when symptoms aren't yet evident.)
