Dr. Richard S. Ostfeld, Senior Scientist at the Cary Institute of Ecosystem Studies, joins us for our latest Please Explain on ticks and Lyme disease. As global temperatures rise, there is an increasing prevalence of ticks, and tick-borne diseases, across the country. Dr. Ostfeld is part of The Tick Project, a five-year study to determine whether neighborhood-based prevention can reduce human cases of Lyme and other tick-borne diseases. He will speak about the prevalence of ticks, why they are spreading and preventative measures we can take.
