Any way you slice it, Lyme disease is an expanding problem. The number of confirmed cases has roughly doubled in the past decade. The map shows the distribution of reported 2004 cases of Lyme disease (in red) as well as the presence of the ticks that can cause it (in yellow and blue). Both the map and the information below confirm that most cases are still clustered in the Northeast and Midwest.
