Revised numbers Wednesday from the Oregon Health Authority dropped the number of COVID-19 cases attributed to Hood River County from three to two.  The OHA explains the case that had been attributed to Hood River County was from out of state.  Wasco County remained at seven cases, while none have been reported in Sherman and Gilliam counties.  The OHA reported 47 new COVID-19 cases in the state, moving the statewide case count to 736.  The 19th fatality in Oregon as a result of the virus was also reported, a 70-year-old woman in Multnomah County with underlying medical conditions.  The OHA also said that updated projections from health researchers show that there is “strong evidence that measures currently in place in Oregon are reducing transmission.”  The most recent data suggest that current social distancing measures could cut transmission rates between 50 to 70 percent if Oregonians maintain the limitations on virus-spreading interactions into early May, which would allow the state to meet the likely demand for hospital beds under current strategies.  The models state health officials released today were prepared by the Institute for Disease Modeling, based in Washington.
