NEW YORK (AP) — Mayor Bill de Blasio is reassuring New Yorkers that the city is ready to handle a potential Ebola outbreak.

He convened a meeting of city agencies at City Hall on Thursday as a display of readiness against the spread of the deadly virus.

Representatives from the Centers for Disease Control and the federal Department of Homeland Security also attended.

De Blasio said that the Ebola cases have been a "painful crisis."

But he said there is "no cause for alarm" in the nation's largest city.

He said the city's hospital system is ready. He's urging New Yorkers to seek medical help if they feel sick.

There has not been a confirmed case of Ebola reported in New York. There has been one fatality in the United States.
