The airline and the mayor’s office said 19 people were confirmed ill. Three passengers and seven crew members went to Jamaica Hospital Medical Center in Queens, and nine other passengers medically evaluated at the scene were released afterward, Dubai-based Emirates said.

CDC spokesman Benjamin Haynes later said 11 people were taken to the hospital, and that the nine others confirmed as sick declined further medical care.

The remainder of the passengers were allowed to leave and clear customs, the airline said. All were advised to call a doctor if they developed symptoms later.

Barbot said 106 people initially reported feeling sick during the flight but the “vast majority” were found to be free of any illness when screened. She said some probably fell into the category of “what we call the worried well.”
