Tonight, we focus on how we're preparing for a potential second wave of COVID-19 cases this fall and winter.

The first segment is hypothetical. Dr. Paul Biddinger, chief of the Division of Emergency Preparedness and the director of Massachusetts General Hospital's Center for Disaster Medicine, talks about how the hospital is and has been preparing for a second wave, including collecting and storing PPE.

The second segment is more real. It appears cases and hospitalizations because of the virus are increasing. Dr. Nahid Bhadelia, associate professor at Boston University's School of Medicine and the medical director of the Special Pathogens Unit at Boston Medical Center, walks us through the numbers and why she's concerned by efforts to re-open right now.
