Almost 1,600 more Utahns tested positive for COVID-19 in the past day — and 24% of them were school-age children.

The Utah Department of Health reported 1,585 new cases, the highest number of new cases in a single day since there were 1,591 on Feb. 2. And 374 of the new cases were among kids in grades K-12. There were 163 cases in children ages 5-10; 82 cases in children 11-13; and 14-18 cases in children 14-18.

The rolling seven-day average for positive tests stands at 1,122 per day, the highest that number since Feb. 8.

Twelve more Utahns died of the coronavirus, and seven of them were under the age of 65.

The case count is up 307 compared to one week ago (1,278 on Aug. 18). It’s almost five times what it was a month ago (331 on July 25), and almost six times what it was three months ago (276 on May 25). Six months ago, there were 655 new cases (on Feb. 25); and a year ago, there were 413 new cases (Aug. 25, 2020).

In the past four weeks, unvaccinated Utahns were five times more likely to die of COVID-19 than vaccinated people, according to a UDOH analysis. The unvaccinated were also 6.5 times more likely to be hospitalized, and 4.9 times more likely to test positive for the coronavirus.
