(Portland, OR)  --  Hundreds of Oregon doctors are urging residents to take proper precautions to prevent the spread of COVID-19 over the Labor Day holiday weekend.  The Oregon Chapter of the American College of Emergency Physicians published an open letter yesterday asking people to limit gatherings to small groups and take those gatherings outdoors wherever possible.  The group also urged people to wear masks and practice proper social distancing.  The letter notes that regional hospitals in Oregon are so overstressed by surging COVID-19 numbers that they're sending ICU patients to San Francisco and Utah.
