What is Lyme disease?

Lyme disease is a bacterial infection you get from the bite of an infected Deer Tick. Lyme disease may cause symptoms affecting the skin, nervous system, heart and/or joints of an individual. Your doctor can diagnose Lyme disease based on:

  • History of possible exposure to infected ticks
  • Lab tests (in some cases)
  • Symptoms


Your history of possible exposure to infected ticks depends on:

  • What your outdoor activities have been
  • Where you have traveled
  • Where you live


There are other diseases that cause illness similar to Lyme disease. Someone with Lyme disease may not have the characteristic bull's-eye rash or remember being bitten by a tick. Lab testing is not recommended for people who don't have symptoms of Lyme disease.
