The omicron outbreak pushed Idaho’s coronavirus case numbers to another weekly record.

The numbers:

Cases: A record, for the third consecutive week.

The state and its health districts counted another 19,667 new cases last week, a 14% increase from the previous week’s record.

Saturday’s overall count: 377,804 confirmed or probable coronavirus cases.

Case backlog: Still growing.

“Data for the most recent two-week period are incomplete,” the state reported on its coronavirus website Monday. “Due to the recent surge in cases, approximately 42,100 outstanding positive laboratory results are pending local public health district review and followup.”

A week ago, the backlog was 37,400 cases.

Child cases: Still surging.

For the week ending Saturday, 2,960 school-age children contracted coronavirus last week, a 22% increase.

The childhood case rate has increased more than fourfold since early January, when K-12 schools reopened after the holiday break.

Positive test rate: Another record, for the third consecutive week.

For the week ending Jan. 22, 38.8% of coronavirus tests came back positive, up from 35.2%.

Any rate above 5% a suggests a virus is out of control.

Hospitalizations: Climbing, across the board.

On Wednesday, Idaho reported 543 COVID-19 hospitalizations and 107 ICU admissions, up 11% and 18%, respectively.

The Department of Health and Welfare last week reinstated crisis standards for hospitals across southern Idaho. The move was driven, in part, by COVID-caused staffing shortages. (Details from Audrey Dutton of Idaho Capital Sun.)

Deaths: The state reported 83 COVID-19 deaths last week, up from 48 the previous week.

Idaho’s COVID-19 death toll stands at 4,405.

That move came days after West Ada’s teachers’ union called for greater COVID-19 transparency from the district.
