I did read this on Politico today:

President Donald Trump is reluctant to declare an expansive emergency to combat the escalating coronavirus outbreak, fearful of stoking panic with such a dramatic step, according to three people familiar with the situation.

Instead, the president is expected to sign within days what the White House calls a more limited designation to allow the federal government to cover small business loans, paychecks for hourly workers and delay tax bills, giving him a way to begin boosting the economy without waiting for Congress to sign off on an economic stimulus package.
