Emirates airline said on Wednesday that 10 passengers were taken ill on a flight to New York to Dubai.
Local New York media earlier reported that about 100 passengers were reported feeling ill.
Passengers “were immediately checked by local health authorities and those needing medical attention will be attended to,” said an airline spokeswoman in a statement.
The New York City mayor’s office said the plane has been quarantined amid reports of numerous ill passengers aboard a flight from Dubai that arrived at New York’s Kennedy Airport.
The Emirates flight landed at about 9:10 a.m. Wednesday.
Video from news helicopters showed the jet sitting on the tarmac surrounded by emergency vehicles and ground control personnel.
A spokesman for New York City Mayor Bill de Blasio said representatives of the U.S. Centers for Disease Control and Prevention were on the scene.
A New York Police Department counterterrorism division tweeted that it was monitoring what appeared to be a “medical situation.”
