Trump has called on people to buy less and promised that stores will remain open.
"We're trying to get people to actually buy less if that's possible," he said. "Buy less..."Don't take everything. Just buy what you need," Trump said, commenting on fears that panic stockpiling on goods will leave the shops empty.
Mr Trump also said he believes that the US economy will recover rapidly after the coronavirus spread reduces.
"We're going to win and I think we're going to win faster than people think, I hope," the US president said.
