Lyme disease results from the bite of an infected tick. It can cause many symptoms, including a bull’s-eye rash and joint pain, and may result in post-Lyme disease syndrome.

Lyme disease was first recognized in the town of Old Lyme, Connecticut, in 1975.

It’s an infectious disease caused by the bacterium Borrelia burgdorferi and, in rare cases, Borrelia mayonii.

B. burgdorferiis transmitted to humans[1] by a bite from an infected black-legged tick, also known as a deer tick. These tiny insects become infected after feeding on infected animals, such as deer, birds, or mice.

According to the Centers for Disease Control and Prevention (CDC)[2], infected ticks transmit Lyme disease in the Northeastern, Mid-Atlantic, and North Central United States, as well as on the Pacific Coast of the United States.
