Where Lyme Disease Occurs Map

Lyme Disease is a serious disease.  Spread by the deer tick, Lyme Disease can be difficult to diagnose and to treat.  Knowing where Lyme Disease occurs can help you understand where you need to be more vigilant about preventing deer tick bites.

The deer tick, or the blacklegged tick, is native to the Eastern US but has a range that moves as far west as the Central US.  It can survive in any climate that has a baseline level of moisture, meaning that it typically does not live in the dry Western climates.
