Responding to the coronavirus in New York will be a "significant financial burden" for New York, Gov. Andrew Cuomo said Monday at a news conference. 

A 39-year-old Manhattan woman has tested positive for the virus, the first New York case. She is a health care worker who recently traveled to Iran and has been in self-isolation, Cuomo said. 

Cuomo, at the news conference on Monday, urged calm, saying it was inevitable there would be positive cases in New York. As of midday on Monday, fewer than 100 cases were reported nationally and two people have died.

"We think we have the best health care system on the planet right here in New York," he said. "So when you're saying what happened in other countries versus what happened here, we don't even think it's going to be as bad in other countries."   

But underscoring how New York officials were taking the situation, Cuomo appeared at a joint news conference with New York City Mayor Bill de Blasio, his sometimes political rival.

"This is a significant financial burden," Cuomo said. "We have no issue with the administration, the management and doing the job. But the financial consequences are highly relevant and at a minimum we would expect the federal government to help with that."

Cuomo last week had announced he would seek a $40 million appropriation from the Legislature to purchase equipment and provide resources to respond to a potential outbreak.
