Lyme Disease

About
In the United States, Lyme disease is caused by the bacterium Borrelia burgdorferi and rarely, Borrelia mayonii . It occurs most commonly in the Northeast, mid-Atlantic, and upper-Midwest regions. Lyme disease bacteria are spread to humans through the bite of infected blacklegged ticks. Typical symptoms include fever, headache, fatigue, and a characteristic skin rash called erythema migrans . If left untreated, infection can spread to joints, the heart, and the nervous system. Lyme disease is diagnosed based on symptoms, physical findings (e.g., rash), and the possibility of exposure to infected ticks. Laboratory testing is helpful if used correctly and performed with FDA-cleared tests. Most cases of Lyme disease can be treated successfully with a few weeks of antibiotics.
Symptoms
Untreated Lyme disease can produce a wide range of symptoms, depending on the stage of infection. These include fever, rash, facial paralysis, an irregular heartbeat, and arthritis.
How it spreads
Lyme disease bacteria causing human infection in the United States are spread to people by blacklegged ( Ixodes ) ticks.
Prevention
Prevent tick bites The best defense against Lyme disease is to prevent tick bites . This will reduce your risk of other tickborne diseases as well. What to do after a tick bite Remove attached ticks as soon as possible . Depending on the type of tick and how long it was attached, antibiotic prophylaxis might help to prevent Lyme disease. Call your doctor if you develop fever, rash, or other symptoms.
Treatment
Early diagnosis and proper antibiotic treatment of Lyme disease are important and can help prevent more serious forms of the disease. Following antibiotic treatment, some people with Lyme disease have prolonged symptoms including fatigue, body aches, or difficulty thinking.
