The two-week stay-at-home order in Minnesota is set to expire at 5 p.m. on April 10, but Gov. Tim Walz says it's possible that the order is extended.

"Early to middle of next week we'll be making that determination based on the data," Walz said Wednesday.

Walz said "we are seeing real evidence that social distancing is working and slowing" the spread of COVID-19, but the concerns are rising with a report from The Washington Post says the national stockpile of personal protective equipment (PPE) for healthcare workers is nearly depleted.

“The stockpile was designed to respond to handful of cities. It was never built or designed to fight a 50-state pandemic,” a source from the Department of Homeland Security (DHS) told The Washington Post. “This is not only a U.S. government problem. The supply chain for PPE worldwide has broken down, and there is a lot of price gouging happening.”

“If you can’t protect the people taking care of us, it gets ugly," a DHS official said.

Walz was on a call with U.S. governors Wednesday and said everyone is "deeply concerned" about the PPE limitations, and says supply chains have been disrupted by a lack of a "real cohesive national strategy" early on in the COVID-19 crisis.

Walz has based some of his decisions on modeling being developed by the University of Minnesota and Minnesota Department of Health, which is expected to include more granular, state-specific data for a new simulation of possible outcomes within the next two weeks.
