Last week, nearly half of Idaho’s new coronavirus cases were traced to just two of Idaho’s 44 counties — Ada and Bonneville.

The trends extended to Idaho’s college campuses.

Boise State University and Idaho Falls’ College of Eastern Idaho both reported case increases last week. Together, the two institutions account for more than 40 percent of new campus cases.

Here is this week’s campus coronavirus case roundup.

Increasing

Boise State University. A second successive week of across-the-board increases.

Boise State reported 47 campus cases for the seven-day period ending Thursday, up from 29 the previous week. Thirty-three cases involved students who live off campus, 12 involved students living on campus, and two cases involved faculty or staff.

Meanwhile, 2.3 percent of campus coronavirus tests came back positive, up from 1.7 percent the previous week.

Ten of Boise State’s 153 isolation beds were in use Friday, up from six the previous week.

College of Eastern Idaho. As case numbers increase significantly in Bonneville County, CEI also reported a spike. The college reported 12 new cases last week, up from two cases the previous week. Nine of the new cases involve employees and three involve students. CEI has reported a total of 184 cases since August.
