Doctors and nurses treating those sick and dying from the coronavirus say the politics of the crisis are complicating treatment efforts. In Springfield, Missouri, the families of some of those hospitalized with the virus don't believe it is real. At a Wisconsin hospital, some refuse to be tested. In Georgia, hospital visitors try to get in with fishnet masks. Others demand to be prescribed the anti-malaria drug hydroxychloroquine that President Donald Trump has championed, even though experts say it is not effective against COVID-19.
