A passenger with suspected coronavirus was on board a flight from San Francisco which landed at Heathrow this morning.
Other passengers on United Airlines Flight 901 have told Sky News the captain told them to stay in their seats after landing because someone had been "taken ill".

Andy West, from Henley-on-Thames, said he knew something was happening when he saw a fire engine had met the plane, which was not allowed to park at the terminal.
He said staff then informed passengers that the individual had suspected coronavirus, or COVID-19, and they would need to wait for officials to board the plane.
The passenger was taken to the back of the plane but Mr West said staff were not wearing any protective clothing, including face masks.
He said everyone was told to fill in a Health England contact form and then after 20-25 minutes they were allowed to disembark.
Mr West said: "I'd be lying if I said I wasn't worried. My reaction was 'wow'."

He added that he was "a bit surprised" they had been allowed to go. Sky News spoke to him as he waited for his luggage in the baggage hall in the terminal.
He said he was not planning to self-isolate but would take every precaution if he suspected he had any symptoms.
