Lyme disease figures soar, mostly in Northeast

US estimates 300,000 cases yearly

New estimates indicate that Lyme disease is 10 times more common than previous national counts showed, the federal government announced Monday, with about 300,000 people getting the disease each year — most in the Northeast.

The updated total, compiled by the Centers for Disease Control and Prevention, is based on data from health insurance claims, laboratories, and public surveys. Past estimates of 30,000 cases a year relied on physicians’ reports to states, and the illnesses were widely considered underreported.
