Hi Reddit, I am Michaeleen Doucleff, a global health reporter for NPR, and I am joined by Rick Ostfeld and Felicia Keesing – disease ecologists from the Cary Institute in New York and Bard College, respectively, who have worked on Lyme disease for more than 20 years. In March, I reported a story for NPR on Lyme disease and tick-borne diseases in the U.S. The premise: Ostfeld and Keesing predict that 2017 will be a particularly bad year for Lyme. But they’re testing a way to stop it. Lyme is already on the upswing. From 2001 to 2015, cases in the U.S. have more than doubled, and they’ve spread around the Northeast and northern Midwest. Ask us anything. We’ll be here from 1PM to 3PM ET to answer your questions about how tick-borne diseases spread, why they’re spreading and what scientists are doing to stop it. Looking forward to hearing from you!
