Lyme disease is the most common vectorborne disease in Maine. Cases have already been reported in 2014, and the number will rise as the weather continues to get warmer.

Lyme disease is a bacterial infection carried by the deer tick.  Cases have been increasing each year in Maine, and occur in all 16 counties. More than 1,375 cases of Lyme disease were reported statewide in 2013, a record high for Maine.  

Lyme disease is most common among school age children and adults older than 65. Most infections occur during the summer months.

The most common early symptom of Lyme disease is an expanding red rash that occurs 3-30 days after being bitten. Fever, headache, joint and muscle pains, and fatigue are also common during the first several weeks. Later features of Lyme disease can include arthritis in one or more joints (often the knee), Bell's palsy and other cranial nerve palsies, meningitis, and carditis (AV block). Lyme disease is treatable, and the majority of patients recover after receiving appropriate therapy.
