Passengers on a flight from Heathrow to Dallas/Fort Worth International Airport were asked to raise their hands if they were from countries with confirmed cases of COVID19.

The clip, filmed on March 14, shows the flight attendant calling out countries and handing out forms for passengers.

"Passengers who raised their hands were given handouts declaring which countries they had travelled to and if they had symptoms of coronavirus.

The entire plane was held at the gate until all forms were completed. The forms were then handed to customs agents, but no further screening for those passengers was required," the filmer told Newsflare.
