BISMARCK, N.D. (AP) — National Guard soldiers have helped to notify 800 people who tested positive for COVID-19 but initially weren’t told. The notification backlog was due to a recent sharp increase in coronavirus cases. It was resolved Thursday largely through shifting the role this week of 50 North Dakota National Guard soldiers, health officials said. The soldiers had been informing people they may have been exposed to COVID-19 and should monitor their health for signs and symptoms of the virus. On Monday, health officials announced the soldiers would instead be notifying those who test positive for the virus.
