NEW YORK (AP) — Health officials say they've received calls from New York City physicians about 88 potential Ebola cases since August but the disease was never detected.

Dr. Isaac Benowitz told the city's Board of Health Tuesday that of those 88, only 11 of the people displayed symptoms of the disease and had recently come from one of the West African countries where it is rampant.

Benowitz said nine ended up having malaria and one had typhoid. None displayed symptoms during the flight to New York.

Health officials detailed the measures they've been taking in recent months to prepare in the event an infected person comes to the nation's most populous city.

They said they're well prepared in the event a case emerges in New York.
