Lyme Disease Information

Lyme disease is an illness caused by the bacterium Borrelia burgdorferi. Lyme disease is the most common tick-borne disease in Maryland. Other tick-borne diseases, such as Anaplasmosis, Babesiosis, and Ehrlichiosis also occur in this area. Learn more about other tick-borne diseases.

Lyme disease is spread by black-legged ticks, also called deer ticks. Deer ticks are very small.


Not all deer ticks spread Lyme disease, only those that carry the bacteria.

Early Lyme disease symptoms may include:

  • Round red rash around the tick bite, like a bull’s eye with a clear center and a ring around it. Not everyone with Lyme will get this rash.
  • Flu-like symptoms – fatigue, headache, fever, and achy muscles and joints.
  • Usually occur within the first month after a bite.

Later symptoms may include:

  • Arthritis
  • Nervous system problems
  • Heart problems
  • Can occur several weeks or months after the bite.
