(UPDATED, 8:57 a.m., with corrected numbers from Nampa School District.)

Idaho shattered its weekly coronavirus case numbers — again — as the omicron surge continues across the state.

For the second successive week, case numbers and positive test rates hit pandemic peaks.

The unsettling weekly numbers:

Cases: The state added 17,191 new coronavirus cases last week — up 28 percent from the previous week’s record.

The state also tallied 4,537 cases Wednesday, a one-day record.

As of Saturday, the state and its seven health districts reported 358,137 confirmed or probable coronavirus cases.

Case backlog: On top of the reported record case numbers, a paperwork backlog just keeps growing.

“Data for the most recent two-week period are incomplete,” the state reported on its coronavirus website. “Due to the recent surge in cases, approximately 37,400 outstanding positive laboratory results are pending local public health district review and followup.”

A week ago, the backlog was 22,000 cases.

Child cases: Continuing to surge.

For the week ending Saturday, 2,431 school-age children contracted coronavirus last week, a 40 percent weekly increase.

The weekly child cases are almost certainly a record; it’s the highest figure since October 2020, when Idaho Education News began compiling data on case numbers by age group.

Positive test rate: Surging, to another staggering weekly record.

For the week ending Jan. 15, 34.1% of coronavirus tests came back positive, shattering the previous week’s record, 26.9%.

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

Hospitalizations: Mixed numbers.

On Wednesday, Idaho reported 491 COVID-19 hospitalizations, up 30% from the previous week.

Meanwhile, ICU admissions decreased. Wednesday’s 91 ICU admissions represent a 7% decline.

Deaths: The state reported 48 COVID-19 last week, a 30% increase.

Idaho’s COVID-19 death toll stands at 4,322.
