K-12 coronavirus case numbers increased slightly last week — but remained in line with recent trends.

The Idaho Department of Health and Welfare reported at least 108 K-12 cases for a seven-day period ending Sunday, compared to 99 cases the preceding week.

Since mid-February, the schools have averaged about 97 cases per week.

The week’s hotspots were scattered across the state:

• Eagle High School: Five cases.
• Athol Elementary School: Four cases.
• Capital High School, Boise: Three cases.
• Moscow High School: Three cases.
• Pocatello High School: Three cases.
• Sawtooth Middle School, Meridian: Three cases.
• Teton High School, Driggs: Three cases.
• Thunder Ridge High School, Idaho Falls: Three cases.
• Twin Falls High School: Three cases.
• West Junior High School, Boise: Three cases.

The weekly reports are a snapshot, and they’re incomplete.

Not every school reports its case numbers weekly. Health and Welfare does not release any case numbers from schools with fewer than 50 students, citing privacy concerns. In some cases, Health and Welfare provides only a minimum number of coronavirus cases for a school.

The highest case numbers for 2020-21, by school:

• Lake City High School, Coeur d’Alene: 152 cases.
• Thunder Ridge High School, Idaho Falls: 139 cases.
• Hillcrest High School, Ammon: 131 cases.
