 We continue the COVID thread on our show today, checking in with those on the front line. This week, Kaiser Permanente Hawaii began recommending visitors wear masks at all its facilities. It's requiring masks for staff because of the increased cases among patients and health care workers. We talked to Dr. Monica Nagiakwadi-Singer this morning. She's a medical director and a pediatric infectious disease doctor and, as it turns out, just recovered from the virus.
