Lyme Disease is a bacterial infection caused by the bacterium Borrelia Burgdorferi. It is transmitted to humans through the bite of blacklegged or deer ticks – Ixodes Scapulari. In most instances, the tick must be attached to the body for 36-48 hours before the bacteria causing Lyme Disease is transmitted to the person or pet.
The CDC estimates that there are about 300,000 cases of Lyme Disease per year, over 96% of which are concentrated in the Northeast and upper Midwest of the United States. Most cases of Lyme Disease occur between May and October.
