Lyme Disease

How is Lyme Disease Transmitted?

  • Infected blacklegged ticks (or deer ticks) transmit bacteria that can cause Lyme disease.
  • Lyme disease transmission usually occurs during the late spring and early summer (May, June, July) when young (nymph stage) ticks are active and feeding. However, adult blacklegged ticks remain active all winter and can also transmit Lyme disease.
  • In most cases, the tick must be attached for 36 to 48 hours or more before the Lyme disease bacterium can be transmitted.
