Idaho has reported its largest one-week increase in coronavirus cases in more than two months.

As of Friday afternoon, Idaho and its health districts reported 3,888 confirmed or probable coronavirus cases, up 15 percent from a week ago.

From April 11 through April 17  — when Idaho was in the midst of a stay-at-home order — Idaho’s coronavirus case numbers increased by 19 percent. Since then, and even during a statewide business reopening plan, weekly increases have ranged from 7 to 13 percent.

Last week, case numbers increased by 8 percent.

The uptick in case numbers comes as state leaders are deferring to local entities in the response to the pandemic.

Gov. Brad Little unveiled two committees Wednesday that will examine school reopening issues. The committees’ work will be advisory in nature, and local trustees will make reopening decisions. Since early June, Little has said the state’s response to coronavirus spikes would move from a statewide stay-at-home order to a regionalized approach.

Idaho’s coronavirus numbers also reached several milestones this week.

• Ada County became the state’s first county with more than 1,000 coronavirus cases. An outbreak linked to several downtown Boise bars contributed to an increase in Ada County cases.
• The state reported 96 new confirmed cases Thursday and 112 new confirmed cases Friday — the largest one-day increases since April 9.
• The number of Idahoans who have recovered from coronavirus passed the 3,000 mark.
