Communications specialist Erin McHenry says state health officials are aware of "a cluster of cases" at the Castaway Club Young Life Camp on Pelican Lake, about 45 miles east of Fargo, North Dakota.

Camp manager Greg Johnson says he's aware of 10 coronavirus cases involving staff members over the past two weeks, with no new infections in the last week.

The number of infected guests wasn't immediately known because cases may have been reported in other states.
