PORTLAND, Ore. — Data from the Oregon Health Authority (OHA) shows some of the largest COVID-19 spikes last week were in Eastern Oregon and Marion County.
In its weekly report published Wednesday, OHA updated the breakdown of cases across the state by ZIP code. The data is current as of 11 p.m. Sunday, Aug. 30. For the third consecutive week, the Ontario area, in Malheur County, saw the biggest spike: 97914 had 107 new cases.
Malheur County is one of five counties on Oregon’s COVID-19 watch list. The list allows the state to prioritize resources, including contact tracing help, in the counties where the virus is spreading more rapidly and health officials cannot trace cases to a known source. Untraced cases, known as sporadic cases, are a marker of coronavirus spreading in a community. Counties with a sporadic case rate of at least 5% over a two-week period have a rapid community spread, according to the governor’s office.
Earlier this week, the Malheur County Health Department expressed concern over the COVID-19 policies in Idaho and the impact those less-restrictive measures, which includes no mask mandates along the border with Malheur County, could be having on the spread of the virus.

Although the areas listed above saw noticeable increases, OHA noted in its weekly report that cases statewide decreased 8% from the week before. The 1,704 known cases during the week of Aug. 24-30 was the lowest weekly case count since the end of June, OHA said. The positive test rate also dropped to 4.4% last week, the lowest proportion in two months, according to OHA.
While there’s been progress in limiting the spread of the virus, Oregon still has a long way to go before benchmarks to resume in-person classes are hit. Experts said the average amount of daily cases would need to about 60. During the week of Aug. 24-30, Oregon averaged 246 cases a day.
OHA also reported there were 73 active workplace outbreaks in the state, and 114 workplace outbreaks that were resolved.
