Model predicts where ticks, Lyme disease will appear next in Midwest states

By drawing from decades of studies, scientists created a timeline marking the arrival of black-legged ticks, also known as deer ticks, in hundreds of counties across 10 Midwestern states. They used these data—along with an analysis of county-level landscape features associated with the spread of ticks—to build a model that can predict where ticks are likely to appear in future years.
