Oregon Governor Kate Brown told a press briefing Friday that at the current rate of COVID-19 spread it would take about 200 days to get students back into classrooms at the current one-to-one transmission rate, but it could happen in as little as six weeks if it drops to .75.  Brown said she told a group of city and county officials this week to step up their efforts to ensure face covering, workplace, and social gathering restrictions are observed.  The governor said she has heard reports of law enforcement on some communities not wearing masks, which she called “unacceptable.”  Brown said the other way to speed the reduction of virus spread would be to bring back business restrictions and perhaps institute travel restrictions, but also said those come with economic costs.
