Financial markets have been reacting to news of the virus' spread because of the potential impact of the disease's outbreak on the global economy.

U.S. and German bond yields resumed their fall while gold prices rose.

Health officials in Nassau County, New York, said on Wednesday that they were monitoring 83 people who visited China and may have come in contact with the coronavirus, but Governor Andrew Cuomo said the state has had no confirmed cases so far.

"We need to more information before markets have a further correction or get comfortable things won't escalate further," said Jason Draho, head of Americas asset allocation at UBS Global Wealth Management, New York.

"Markets will be very jumpy until there's increasing confidence the virus is abating and that it won't be a global pandemic," he said.

On Wall Street, the Dow Jones Industrial Average fell 80.13 points, or 0.3%, to 27,001.23, the S&P 500 lost 5.18 points, or 0.17%, to 3,123.03 and the Nasdaq Composite added 29.90 points, or 0.33%, to 8,995.52.

Oil prices fell after hundreds of new coronavirus cases were reported in Europe and the Middle East, while the New York state report added to the concern that energy demand would decline.

"It's still all about the virus here," said Bob Yawger, director of energy futures at Mizuho in New York. "It's going to be hard for risk assets to gather momentum."
