Stock markets are falling around the world after the number of coronavirus cases surged in Italy and South Korea, putting two more major economies at risk from a virus that has already caused widespread disruption in China.
The Dow plunged as much as 997 points, or 3.4%, when US markets opened on Monday. The S&P 500 fell up to 3.2%, and the Nasdaq lost nearly 4.3%. The VIX, a measure of market volatility, shot up 40%.
The indexes have since recovered slightly, but the Dow is still off nearly 800 points, or 2.7%.
