Oregon state epidemiologist Dr. Dean Sidelinger said during a media briefing today that while the latest modeling suggests that current social distancing measures could be cutting COVID-19 transmission rates between 50 to 70 percent, those steps must continue to be observed to keep flattening the curve.  Sidelinger says the model shows with the current social distancing measures in place for Oregon that COVID-19 cases would rise slowly enough to allow hospitals to provide the care those who are sick need.  But he quickly adds the model does assume a couple of things:  people continuing to observe social distancing measures, and front line medical personnel having a supply of personal protective equipment.  Sidelinger says the COVID-19 cases being discovered now are probably involving people infected two-to-three weeks ago.
