(Portland, OR)  --  State health officials are saying at least 88-percent of all active cases of COVID-19 in Oregon are the Delta variant.  Just a few weeks ago, the Delta variant accounted for just 33-percent of cases.  Now, Dr. Paul Cieslak with the Oregon Health Authority says that unvaccinated Oregonians are at a much greater risk of contracting the descendant of the novel coronavirus strand than when it first surfaced in the state 16 months ago.  The Delta variant, experts say, spreads twice as fast as the original and appears to make infected patients sicker than the novel COVID-19.
