NEW YORK (Reuters) - Stocks and oil prices resumed their fall on Wednesday after authorities said more than 80 people were being monitored for the novel coronavirus in New York state’s Long Island, adding to concern over its spread in Europe, Asia and the Middle East.

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

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

Health officials in New York’s Nassau County 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 (get) 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 in 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 123.77 points, or 0.46%, to 26,957.59, the S&P 500 lost 11.82 points, or 0.38%, to 3,116.39 and the Nasdaq Composite added 15.16 points, or 0.17%, to 8,980.78.

The S&P rose more than 1.7% at its session high.

Emerging market stocks lost 1.25%. Brazil’s Bovespa index tumbled 7%, catching up with the selloff after a long carnival holiday. Brazil confirmed the first case of coronavirus in Latin America on Wednesday.

Argentina’s S&P Merval fell 5.65%.

Nikkei futures rose 0.77%.

Oil prices fell after hundreds of new coronavirus cases were reported in Europe and the Middle East. The New York state report added to concerns 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.”
