A nationwide effort led by scientists at Northern Arizona University has detected ticks that can carry Lyme disease and other tick-borne illness in over 80 counties in the United States where such ticks had not previously been recorded. Researcher Dr. Nate Nieto notes, “People should be aware of ticks and tick-borne disease, even when they may think there’s not a recorded incidence of a tick in a county.” PLOS One, July 2018
