Moody's Analytics said in a Thursday note that there is a 40% chance that the coronavirus outbreak turns into a pandemic — when an epidemic spreads globally and affects a large number of people worldwide — and that if such a situation arises, then it would "result in global and U.S. recessions during the first half of this year."
"The economy was already fragile before the outbreak and vulnerable to anything that did not stick to script," Moody's said, adding that the new virus which came out of nowhere is "way off script." The ratings agency said that the virus poses downside risk to the U.S. economy and though there are limits to monetary policy, the Federal Reserve "may need (to) eventually step in." That said, an emergency rate cut from the Fed is unlikely, Moody's said. — Roy Choudhury

The Centers for Disease Control and Prevention said it revised its guidelines to allow clinicians across the U.S. to test more people suspected of carrying the new coronavirus.

Some lawmakers criticized the CDC's previous guidance as too restrictive. The new guidelines, which were posted to the CDC's website Thursday, appear to place more power in the hands of local health practitioners to determine who should get tested. — Feuer
