Idaho’s coronavirus trends all moved in the right direction last week.

New case numbers continued to head downward — across the state and in schools as well.

This week’s numbers:

Cases: A fourth consecutive weekly decrease.

The state and its health districts still added 9,131 cases last week, but that represents a 20% decrease.

The state has reported 423,756 confirmed or probable coronavirus cases.

Case backlog: Dwindling.

“Data for January are incomplete,” the state reported on its coronavirus website Sunday. “Due to the surge in cases Jan. 10-Feb. 5, approximately 17,000 outstanding positive laboratory results received during that time are pending local public health district review and followup.”

A week ago, the backlog was 25,700 cases.

Child cases: A fourth successive weekly decrease.

For the week ending Saturday, 1,332 school-age children contracted coronavirus, an 18% decrease.

By comparison, nearly 3,000 school-age children contracted coronavirus in the seven-day period ending Jan. 29.

Positive test rate: A fourth consecutive week of sharp decreases.

For the week ending Feb. 19, 10% of coronavirus tests came back positive, down from 16.4%.

As this rate continues to decline, it moves closer to the 5% mark — a threshold that suggests a virus is under control.

Hospitalizations: Another week of decreases across the board.

On Wednesday, Idaho reported 276 COVID-19 hospitalizations, a 27% decrease.

The state counted 62 ICU admissions, down 28%.

Six children were in pediatric beds with COVID-19, down from 10 the previous week.

Deaths: Also declining sharply.

While 54 Idahoans died of COVID-19 last week, that is a 56% decrease from the preceding week.

Idaho’s COVID-19 death toll now stands at 4,730.
