Lane County officials announced Tuesday night that a woman in the county who died Saturday is now believed to have died from COVID-19.

The case marks the second Oregon fatality suspected to have been caused by the virus. Lane County officials said the woman, 60, was brought into PeaceHealth Sacred Heart Medical Center at Riverbend in Springfield on Saturday as she was having a heart attack. After she died the same day, employees submitted a coronavirus test to the Oregon State Public Health Lab, and the test came back Tuesday night as positive for the virus.

The woman lived in the Eugene-Springfield area. She did not live in an assisted living facility. The medical examiner’s office still has to determine a cause of death, but Lane County officials called the positive test “concerning.”

County officials said they would investigate the case and contact any people who may have been exposed to COVID-19.

Lane County officials had announced earlier Tuesday that a 69-year-old county resident had also tested postive for the disease. He is in stable condition and recovering at home. The man first showed symptoms March 1 and was tested by his healthcare provider 12 days later. Officials said they don’t know how he contracted the virus.

Because the woman wasn’t among the previously counted coronavirus cases in Oregon, her death marks the 68th case in the state.

There are now known coronavirus cases in 14 of Oregon’s 36 counties: 22 in Washington County; 15 in Linn County; six each in Clackamas and Deschutes counties; four in Marion County; three in Multnomah County; two each in Benton, Jackson, Lane and Umatilla counties, and one each in Douglas, Klamath, Polk and Yamhill counties.

State health experts have said they expected the number of reported cases to increase as testing capacity expands throughout Oregon and as the virus continues to spread rapidly among people.
