This article offers a general overview on Lyme disease. For specific information see:

Alternative Names:

Borreliosis

Causes, incidence, and risk factors:

Lyme disease is caused by the bacteria Borrelia burgdorferi ( B. burgdorferi) . Certain ticks carry the bacteria. The ticks pick up the bacteria when they bite mice or deer that are infected with Lyme disease. You can get the disease if you are bitten by an infected tick.

Lyme disease was first reported in the United States in the town of Old Lyme, Connecticut in 1975. Cases have now been reported in most parts of the United States. Most occur in the Northeast, upper Midwest, and along the Pacific coast. Lyme disease is usually seen during the late spring, summer, and early fall.

There are three stages of Lyme disease.

Risk factors for Lyme disease include walking in high grasses, taking place in activities that increase tick exposure, and having a pet that may carry ticks home.
