Oregon’s fourth known death from the new coronavirus was announced Friday evening, as Marion County officials confirmed a woman had died from the virus.

Marion County Commissioners Sam Brentano, Kevin Cameron and Colm Willis said they were saddened to report the death and offered sympathies to the person’s family.

Oregon Health Authority reported on Saturday that the woman, 72, tested positive on March 15 and died on March 20 at Kaiser Permanente Sunnyside Medical Center. She had underlying medical conditions.

The woman was one of 17 Marion County residents who have tested positive for the virus so far, and one of 115 in Oregon. Three others have died, including a Lane County woman, 60, a Multnomah County man, 70 and a Washington County man, 71.
