Minneapolis doctor wipes away tears in describing Covid-19's toll on hospital workers

In the past seven days, Minnesota has had the fifth-most new coronavirus cases per capita in the country, behind only the Dakotas, Wyoming and New Mexico, according to data from Johns Hopkins University. The swell of new infections has pushed hospitals -- and perhaps more importantly, the people who make them go -- to the brink. Dr. Shirlee Xie took care of five patients with Covid-19 the last time she worked at her Minneapolis hospital. 'I can't prevent anyone from getting Covid, all I can do is try to keep Covid from killing you,' she said. 'So we are not the front lines. We are the last line of defense, and so what we need is for people to step up and to wear masks and to distance from people and just try to keep themselves safe and everybody else safe.'
