Early months

On February 28, 2020, the Oregon Health Authority (OHA) reported the first case of suspected coronavirus in a resident of Washington County who had not traveled to an infected area, likely indicating that the virus had been contracted within the community.^[4] Because he was identified as an employee at Forest Hills Elementary School in the Lake Oswego School District in adjacent Clackamas County, the school was closed for three days for deep cleaning.^[4][5] The case was confirmed as coronavirus by the Centers for Disease Control and Prevention (CDC) on March 3.^[6] On March 1, Oregon confirmed its second case, a household contact of its first case.^[7] The employee, later identified as the school building engineer, was treated with Remdesivir and was released from the hospital more than two months later.^[5]

On March 7, health officials identified four new presumptive positive cases among residents in Jackson, Klamath, and Washington counties.^[8] On March 8, the OHA added 7 new presumptive positive cases to Oregon's count.^[9] On March 10, the OHA announced Multnomah County's first presumptive positive case, bringing Oregon's total to fifteen cases in seven counties.^[10] On March 11, OHA confirmed four new cases, one new case each in Deschutes, Marion, Polk, and Umatilla counties.^[11] They later announced Linn County's first two presumptive positive cases.^[12]

On March 16, 2020, Providence Health Systems, Kaiser Permanente, Legacy Health, and Oregon Health & Science University formed a coalition to set up a regional health system in the state in order to address anticipated need for capacity and coordination to address the outbreak.^[13]

Amid coronavirus outbreaks at nursing homes, including those run by Avamere, the company donated $20,000 to a PAC tied to Oregon governor Kate Brown.^[14]

42-year-old Vladislav V. Drozdek was arrested on March 23 trying to sell stolen N95 hospital masks in Beaverton. The masks were donated to local hospitals.^[15]

A study by the Oregon Health Authority found that 1% of subjects had developed COVID-19 antibodies. This is ten times the rate found via conventional testing. Between May 11 and June 15 in 2020, 897 blood samples were collected. Of those, 9 contained antibodies.^[16]

Later events

In August and September 2021, despite wide availability of vaccines, the most severe wave of COVID-19 infections statewide caused Oregon hospitals to cancel elective procedures and degrade medical care for non-emergency patients. Approximately four out of five COVID-19 patients were unvaccinated, meaning most of the hospitalizations were preventable.^[17]

Cases

The Oregon Health Authority publishes weekly outbreak reports for COVID-19 cases, sorted by active and resolved cases in specific workplaces, senior care facilities, child care facilities, and K–12 schools.^[18] A detailed weekly data report covering clinical characteristics, demographics, weekly hospitalizations, and recovery time is also available.^[19]

An outbreak occurred at the 154-bed Edward C. Allworth Veterans' Home in Lebanon, Linn County. By March 16, 2020, the virus was confirmed in 13 residents (most over age 70) and one healthcare worker. With 151 residents and 225 workers, the county health director said, "I can't stop it. I can't stop the virus. I can't make test kits appear", but there was some optimism that the spread would be slow since the retirement home is divided into eleven housing units with 14 residents each. In 2016, the average resident age was 85, with an average length of stay being 50 days.^{[20][21][22][23][24]}

In Portland, Healthcare at Foster Creek (operating as St. Jude Operating Company with Melchor Balaz as its registered agent, part of Benicia Senior Living), had 119 cases and 29 deaths by mid-May 2020. The facility's first case was reported on March 24. An employee reported a lack of PPE to Oregon OSHA on March 26, though an Oregon Department of Human Services (DHS) investigation found it was "unsubstantiated for violations". Five deaths were reported in the week following the complaint. DHS and the facility agreed to a Letter of Intent for assistance on staffing and PPE, and the two signed with American Medical Response to assess and transport residents. DHS conducted a 3-day inspection beginning April 12; the facility had 10 deaths by then. On April 15, the inspection reported they "failed to ensure appropriate measures .. to prevent the spread of COVID-19", and that it "presents an immediate risk" to the patients and staff. DHS revoked new admissions at the facility, appointed a temporary management consultant, and inspected the facility daily. By April 16, there had been 50 cases and 14 deaths. On April 18, Oregon's Office of Emergency Management issued a partial evacuation order. DHS conducted a second significant survey of the facility beginning on April 24, and on April 28 CMS issued a "notice of involuntary termination" if the facility didn't correct its operating conditions by May 17. DHS had reports that coronavirus-positive staff were working in the facility, though not directly with patients. By May 5, there were 117 cases and 28 deaths; 55 patients had been sent to the hospital. Their fatalities were over half of all coronavirus fatalities in Portland. The facility's license was suspended on that date, effective immediately, meaning the facility was closed and the remaining 11 residents were evacuated by DHS.^{[25][26][27][28][29][30][31][32][33][34]}

Also in Portland, Laurelhurst Village, part of the Avamere senior care community, reported 48 cases with four deaths by May 12, 2020, up from 38 cases and four deaths by April 14. The cluster was publicized by The Oregonian on April 3, as DHS refused to publish counts until mid-April. On April 3, The Oregonian located 14 residents and 15 staff confirmed with COVID-19. On April 9, the facility opened 47 beds for coronavirus patients who had been released from a hospital as part of an Oregon Department of Human Services contract through the state. At least one complaint had been filed to OSHA on April 6.^{[25][14][26][35]}

Village Healthcare in Gresham had 36 cases and two deaths by April 30. Several staff complaints had been filed with OSHA.^[26]

Another large outbreak was at Salem's Prestige Senior Living Orchard Heights assisted living facility, having at least 41 cases and three deaths by May 12. The first case had been confirmed on April 30.^[36]

Salem Transitional Care, also part of Avamere, had 26 cases and three deaths by May 12, up from 5 cases and one death by April 14. The facility is licensed for 80 beds.^[25][14]

In early June, 124 cases were linked to Pacific Seafood in Newport, Oregon. Lincoln County (where Newport is located) became the first county in Oregon to make mask wearing mandatory on June 17.^[37]

In early June the Oregon State Penitentiary had 167 cases, and Townsend Farms in Fairview, Oregon had 51 cases.^[37]

The Lighthouse Pentecostal Church in Union County's Island City is the site of the largest outbreak in the state. By June 16 there were 236 cases linked to the church, out of 240 cases in the county. It was noted that the church held in-person services without social distancing or masks in April and as late as May 24, and the church had also held a wedding and a graduation, each attended by over 100 people. The May 24 service was announced on Facebook, stating "In accordance with President Trump, Lighthouse Church ... will be open. We will be having regular services as of Sunday 24, 2020". Union County commissioners Donna Beverage and Paul Anderes were part of a "secret meeting" by leaders of seven counties held on June 11 to make "battle plans" to reject the coronavirus restrictions put in place by the governor.^{[38][39][40][41][42]}

On June 23, 2020, 37 cases in Hermiston, Oregon were traced back to a food facility operated by Lamb Weston that will remain closed until further notice.^[43]

A cluster of 15 cases occurred among employees at the Oregon Beverage Recycling Cooperative's Eugene processing facility located in the same building as the BottleDrop redemption center on October 8, 2020.^[44]

On May 6, 2021, the Peoples Church in Salem, Oregon had 74 cases, including a Lead Pastor and his spouse being hospitalized with COVID-19.^[45] The church continued services within four days after the outbreak. The Peoples Church had previously joined a lawsuit against COVID-19 restrictions that "infringe on religious liberty far more than is necessary to preserve public health and safety,".^[46] By May 10, 2021, the church outbreak was resolved at 89 cases.^[47]

For the week ending August 25, 2021, the three largest active workplace clusters in Oregon were Amazon Troutdale (345 cases), Salem Hospital (299 cases), and Amazon Aumsville (185 cases). All three locations had been under investigation since May 2021.^[48]
