BOISE, Idaho — Officials say Idaho has more than 40,500 confirmed cases of the coronavirus and some health experts are warning that the state in the western U.S. is entering its third wave of new infections.

Former St. Luke’s Health System CEO Dr. David Pate is a a member of the state’s coronavirus task force and says Idaho is being hit with what could become its largest spike of cases so far as students return to school and colder weather limits outdoor activities.

Brigham Young University-Idaho officials warned students last week that that the school could close its campus if people flaunt social distancing and mask requirements and cases continue to rise.
