Several coronavirus numbers showed some signs of improvement last week — including new case numbers.

But it’s hard to say exactly what’s driving the decrease in the case numbers.

As of Sunday, the state and its seven health districts reported 268,727 confirmed or probable coronavirus cases. The week’s 8,306 new cases represent an 11 percent decrease from the preceding week.

But last week, Department of Health and Welfare Director Dave Jeppesen and deputy state epidemiologist Kathleen Turner both told reporters they see no plateau in Idaho’s coronavirus surge.

The state’s coronavirus website still reports a backlog in processing cases. “Case data for the most recent two-week period are incomplete. Due to the recent surge in infections, case investigation data are missing for approximately 8,600 outstanding positive laboratory results that are pending local public health district review and followup.”

A week ago, the state reported a backlog involving 9,500 cases.

While the case numbers may be confusing, other metrics appeared to be slowly shifting away from grim pandemic peaks:

Child case numbers. For the week, 1,348 5- to 17-year-olds contracted coronavirus, a one-week decrease of 6 percent.

As of Wednesday, seven pediatric patients were hospitalized with COVID-19, down from a peak of 15 on Oct. 2.

No Idaho children have died of COVID-19.

Hospitalizations. Overall COVID-19 hospitalizations remain high, but they have tailed off somewhat from peak numbers during this current outbreak.

As of Wednesday, hospitals counted 709 COVID-19 admissions and 176 COVID-19 ICU patients. On Sept. 24, both numbers peaked at 793 and 213, respectively.

However, all Idaho hospitals continue to operate under crisis standards of care, which could allow overburdened hospitals to ration care.

Deaths. An unsettling milestone last week, as the state’s COVID-19 death toll eclipsed the 3,000 mark.

The state reported 159 COVID-19 deaths last week, down from a record 210 deaths the previous week.

In all, 3,122 Idahoans have died of COVID-19.

Positive test rates. A third successive week of decreases. For the seven-day period ending Oct. 2, 14.6 percent of coronavirus cases came back positive, down from 15.2 percent.

Test rates are considered a leading indicator of an outbreak, so the decline in test rates could be encouraging. However, any rate exceeding 5 percent is a sign of an outbreak that is out of control.

Vaccinations. Nearly 12,000 Idahoans completed their vaccinations last week.

Current vaccination rates:

• Overall: 52.9 percent. (Last week: 52.1 percent.)
• 12- to 15-year-olds: 29 percent. (Last week: 28 percent.)
• 16- and 17-year-olds: 36 percent. (Last week: 35 percent.)
• 18- to 24-year-olds: 41 percent. (Last week: 40 percent.)

Editor’s note: School districts and colleges and universities do not count and report cases identically. The case numbers measure trends within a district, college or university, but they don’t provide comparisons between schools or districts.
