‘Virus outbreak’ panic at 40,000 feet as passengers begin falling ill mid-flight

Apart from a fear of flying, one of the things many passengers dread is falling ill mid-flight. Being 40,000 feet in the air with no doctor on board is hardly a reassuring thought, so imagine the worry when several people suddenly become extremely unwell around you, cabin crew start wearing face masks and the pilot announces that medical teams will be waiting when you land.

That was the situation aboard a Eurowings flight from the Greek island of Rhodes to Düsseldorf on Sunday, October 18, when several passengers developed gastrointestinal symptoms, prompting the crew to request priority landing and triggering a major emergency response at the German airport. Three passengers were assessed by medical teams and taken for hospital care with Norovirus being raised as the possible cause.

Cabin crew put on face masks

For those on board, the uncertainty was another source of major anxiety. With several people unwell and the cause unknown, passengers had little way of knowing whether they were witnessing an isolated medical emergency or a potentially contagious illness spreading through the cabin.

One passenger described how the situation unfolded during the journey. Speaking to German broadcaster RTL, she said she and her partner initially noticed little beyond one passenger who appeared unwell. Around an hour into the flight, however, they noticed cabin crew wearing face masks. The passenger said this made her suspect an infectious illness might be spreading on board, although she had no confirmation of what was causing the symptoms.

The pilot proceeded to informed the passengers that it was a special situation and that medical teams would be waiting when they landed. After the aircraft reached Düsseldorf, three people wearing full protective clothing boarded and asked passengers about their symptoms. According to the witness, those on board were not immediately allowed to leave, and passengers reportedly waited until around 11.30pm before being permitted to disembark. The delay left some travellers frustrated and anxious, with little information about what was happening or whether they might also be at risk.

Why emergency services were waiting at the airport

The flight, Eurowings EW9631, was carrying 212 passengers and seven crew members. When several people reported feeling unwell, the crew requested priority landing so medical assistance could meet the aircraft. Düsseldorf Airport activated a precautionary mass-casualty alert because the number of people who might need treatment was initially unknown. The airport fire service sent eight emergency vehicles, with additional crews and ambulances from Düsseldorf’s professional fire brigade also attending. 

A mass-casualty alert does not necessarily mean that a large number of people have been confirmed as seriously ill. It allows emergency services to prepare enough resources to respond if many people need help at once. In this case, the situation proved less serious than initially feared. Medical staff assessed three passengers, with reports indicating that two were taken to hospital. Eurowings said the affected passengers sought hospital care as a precaution. The remaining travellers were able to continue home, and airport operations were not disrupted.

Is norovirus to blame?

Norovirus is currently the main explanation for the gastrointestinal symptoms, but it has not been confirmed as the cause. Eurowings said the reason for the passengers’ illness remained unclear while the incident was investigated. Norovirus can cause sudden vomiting and diarrhoea and spreads easily through close contact with an infected person or contaminated food and surfaces. Its rapid spread in enclosed settings can make suspected cases particularly concerning, including on aircraft where passengers share a confined space for several hours.

However, similar symptoms can have several causes, including other infections and food poisoning. The symptoms reported on this flight are not enough to establish a norovirus outbreak. There is also no confirmed evidence that the passengers contracted an infection in Rhodes or that the incident was connected to an outbreak on the island.

For the passengers onboard the flight the most unsettling part of an incident like this can be not knowing what is happening. While emergency teams were prepared for a potentially serious situation, the available reports indicate that only three passengers required medical assessment. Until the cause is established, norovirus remains a possibility rather than a confirmed explanation for what happened aboard the flight.
