Both in terms of cases and fatalities, Idaho’s coronavirus pandemic passed two grim milestones this week.

Idaho has recorded a record number of new cases in the past seven days. The state and its seven health districts reported 47,498 confirmed or probable coronavirus cases Friday afternoon. New cases exceeded the 4,000 mark for the first time.

The new case numbers translate to a 9 percent weekly increase, unchanged from last week.

Meanwhile, more than 500 Idahoans have now died from COVID-19. The death toll now stands at 506.

As case numbers continued to climb statewide, at least 17 counties reported increases of 10 percent or more. The hotspots include Madison County (a 39 percent increase), Franklin County (31 percent), Bannock County (23 percent), Latah County (22 percent), Caribou County (21 percent), Lemhi County (19 percent), Minidoka County (16 percent), Cassia County (15 percent), Twin Falls County (15 percent), Teton County (14 percent), Gooding County (13 percent), Bingham County (12 percent), Bonneville County (12 percent), Jefferson County (12 percent), Nez Perce County (12 percent), Idaho County (11 percent) and Bonner County (10 percent).

In other coronavirus headlines from the week:

K-12 case numbers double. On Friday, the Department of Health and Welfare reported at least 103 new coronavirus cases in public and private K-12 schools, up from a minimum of 51 cases a week ago. The highest number of new cases occurred at North Star Charter School in Eagle, which reported nine new cases for the week and 30 for the school year. The House of the Lord Christian Academy, a private school in Oldtown, reported five new cases.

A warning from the White House. Suggesting a link between coronavirus outbreaks and school reopenings, a White House task force said Idaho might need to shift to online classes in several communities. The Sunday report also recommended shifting to online learning at the University of Idaho, Boise State University and BYU-Idaho, due to high positive test results among 18- to 24-year-olds.

An uneven testing rollout. The state received its first batch of rapid coronavirus antigen tests, but testing won’t begin until next week. And some local health districts aren’t talking about their testing plan. Idaho will receive more than 500,000 tests from the feds, and Gov. Brad Little wants to focus on testing teachers and school employees.

District updates. Frustrated by the district’s plans to phase in face-to-face learning, a parents’ group said it will try to recall West Ada’s five trustees. Despite rising coronavirus case numbers, the Boise School District will continue to phase in a hybrid of face-to-face and online learning, with the blessing of local health officials.
