The number of newly identified coronavirus cases fell dramatically for a third consecutive week, returning Oregon to levels not seen since the first week of October.

The state recorded 2,260 confirmed or presumed infections for the week ending Sunday, Feb. 21, a whopping 35% decrease from the previous week.

Oregon’s decline in confirmed and presumed infections came amid a 31% drop in weekly testing. But the drop in testing didn’t impact the rate of tests that came back positive, with a 3.5% weekly positivity rate, up only one-tenth of a point from the previous week.

That suggests Oregon’s declining case counts aren’t entirely the result of less testing.

ZIP codes outside the Portland area again saw the most coronavirus cases last week, with no ZIP in the metro recording even 35 new cases.
