Host Ginny Chadwick is joined by Dr. Richard Martinello, medical director of infection prevention at Yale New Haven Hospital. They tackle the complicated topic of virus transmission. How does the virus infect the body? What happens upon the virus "arriving" in a person's nose or mouth? How long can the virus linger in the air? And just how far can respiratory droplets that contain the virus travel? Dr. Martinello breaks down answers to these questions and many more in today's show.
