The Oregon Health Authority Thursday reported 1,122 new confirmed and presumptive coronavirus cases. That’s the highest number of cases reported in a single day since the beginning of the pandemic.
That brings the state’s total number of known cases to 53,779. OHA also reported four new deaths bringing the state’s death toll to 746.
The health authority said small gatherings continue to be driving virus transmission.
“A portion of this week’s rising cases can be attributed to at least five Halloween events, from small social gatherings to a party attended by more than 100 people,” the agency said in a news release.
Thursday’s cases are still under investigation and cannot yet be attributed to a source, the agency said.
The bulk of new cases Thursday continued to come from the Portland metro area with 351 in Multnomah County, 169 in Washington County and 102 in Clackamas County.
Jackson County also saw 123 new cases Thursday.
This past week, from Nov. 2 to Nov. 8, OHA recorded 5,177 new cases. This is the third consecutive week daily case counts have set a record high, OHA said.
