Lyme disease is spread by the bite of an infected tick. In the United States, an estimated 300,000 infections occur 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 greatest risk.. But you and your family can prevent tick bites and reduce your risk of Lyme disease.
