(not a SciFi script but could be a good start for one but probably would be rejected because who would believe that it could be so easy to carry a potential killed disease from Saudi Arabia to the USA in a matter of hours and not be stopped and taken off the plan and all on the flight put in isolation?)
The passenger, who is not a UK national, was on British Airways Flight 262 from Riyadh to London, and transferred at Heathrow for onward travel to the USA, where they were later hospitalised with suspected MERS-CoV.
The risk of the infection being passed to other passengers on Flight 262 is extremely low. However, as a precautionary measure, Public Health England has contacted UK passengers who were sitting in the vicinity of the affected passenger to provide health information.
Any UK based passengers on Flight 262 on April 24 who have since become unwell or experienced respiratory symptoms, such as shortness of breath are advised to contact NHS 111.
PHE will also work with the US health authorities to contact any UK passengers on the April 24 onward flight from London to Chicago, American Airlines Flight 99.
