School districts across Wyoming are making the decision to leave their buildings closed for the remainder of the school year.

The decisions by school officials in communities including Pine Bluffs, Casper and Powell come as the number of confirmed coronavirus cases in Wyoming increased by 19 on Monday, led by the growth of 15 cases in Fremont County.

Although some districts have not yet decided whether classes will resume before the summer break, others are citing continued requirements for social distancing as making regular education techniques unworkable.

“It’s pretty hard to facilitate school when you’re trying to social distance en masse,” said Jon Abrams, superintendent of Laramie County School District No. 2 in Pine Bluffs.

Powell school officials said with state orders closing school buildings until May 15 remaining in place, they decided the transition from home education back to the classroom would be too difficult.

Jay Curtis, superintendent of Park County School District No. 1 in Powell, said transitioning to home-based education earlier this year was tough.

“I think it would be just as much of a monumental task to transition them back into school,” he said.

Meanwhile, the Wyoming Department of Health, in its daily coronavirus update, said the number of confirmed cases grew to 389 on Monday, an increase of 19 over Sunday.

Much of the increase could be traced to 15 new cases detected in Fremont County. Officials there had predicted their case numbers would increase with increased testing and contact tracing.

As of Monday, Fremont County had 98 cases; Laramie County had 89 cases; Teton County had 64; Natrona County had 39; Campbell County had 14; Sheridan County had 12; Converse and Johnson had 11; Sweetwater had 10; Albany had seven; Lincoln and Uinta had six; Crook and Washakie had five; Carbon had four, and Goshen had three. Big Horn, Hot Springs, Niobrara, Park and Sublette counties each had one case.

No cases have been detected in Platte or Weston counties.

The number of laboratory-confirmed and “probable” recoveries went up by one on Monday to total 343. The number includes 249 laboratory-confirmed recoveries and 94 “probable” recoveries.

Model change: One of the most prominent computer models predicting the impact of the coronavirus on various states is projecting higher deaths for Wyoming from the virus than it did two weeks ago. The model from the University of Washington’s Institute for Health Metrics and Evaluation predicts Wyoming will see 166 deaths from the virus, compared to its projection of 34 two weeks ago. The model also predicts the state’s deaths will peak at 12 per day on May 3. So far, seven deaths in Wyoming have been attributed to coronavirus.

Gordon is to announce modified restrictions this week that may allow some businesses affected by his orders to open on a limited basis.
