An Emirates flight from Dubai was held on the tarmac at New York’s John F. Kennedy airport on Wednesday after several crew members and passengers reported feeling sick.

The 14-hour flight landed at JFK shortly after 9 a.m. ET, according to FlightAware. It was quarantined for several hours as officials screened passengers. At least 10 passengers reported feeling sick and were taken to a local hospital, the airline confirmed in a statement on Twitter.

The plane was quarantined and members of the Center for Disease Control and Prevention (CDC) and Port Authority of New York and New Jersey screened all passengers and crew members before they could leave the aircraft.

According to the press secretary for New York City Mayor deBlasio, at least 19 people in total were sick with what is likely the flu. Nine people refused medical attention at the airport.

One passenger documented the experience of going through CDC processing on Twitter. Passengers were required to fill out forms and have their temperature taken as they exited the plane.

Shortly after noon, all the passengers had disembarked the plane. There were at least 500 people onboard the flight from Dubai.

According to local CBS News, there was no evidence of a security or terror issue on the flight.
