CLACKAMAS COUNTY, Ore. (KOIN) — The last full week of November marked the sixth week in a row of record high coronavirus cases according to the Oregon Health Authority. The agency’s weekly report from November 23-29 shows 9,100 new cases, 398 hospitalizations, and 86 deaths.

The impact of the Thanksgiving holiday on case numbers remains to be seen due to a lag between when people catch the virus and when symptoms appear. The past several months have shown spikes in COVID-19 tallies after every holiday, though.
