Lyme disease is spread by the bite of an infected tick. In the United States, an estimated 476,000 infections are diagnosed and treated each year. If you camp, hike, work, or play in wooded or grassy places, you could be bitten by an infected tick.
People living in or visiting New England, the mid-Atlantic states, and the upper Midwest are at the greatest risk. Infected ticks can also be found in neighboring states and in some areas of Northern California, Oregon, and Washington. But you and your family can prevent tick bites and reduce your risk of Lyme disease by protecting yourself from tick bites, performing daily tick checks, removing attached ticks quickly and correctly, be alert for signs and symptoms of lyme disease, prevent ticks on animals, and creating tick-safe zones in the yard.
