Historically, only certain pockets of the United States posed a risk for tick-borne disease, such as Lyme disease, anaplasmosis, babesiosis, ehrlichiosis, and Rocky Mountain spotted fever. However, with recent reports of increase in confirmed cases throughout multiple areas, it's clear the geographic range of ticks is expanding and large areas of the population are now at risk.
