We turn to doctors on the frontline in two of our nation’s top medical cities, San Francisco and Boston. Dr. Anita Demas gives it to us straight on how to deal with it when you are sick and Dr. Anna Cervantes-Arslanian, one of five critical care directors running Covid-19 response for the Boston Medical's ICU team, asks us all to stay in for the sake of the health care workers.   These doctors took an oath to save lives and by doing so today risking their own. We hear it in their voices as mothers, doctors, generals on the frontline.
