Heathrow will begin to screen arrivals for Covid-19 symptoms using thermal cameras, starting from Thursday (21 May).
The cameras will assess passengers arriving at Terminal 2 – currently being used predominantly for European flights – for signs of fever, Heathrow chief executive John Holland-Kaye told Sky News.
Holland-Kaye said the trial, part of a wider effort by the airport to halt the spread of coronavirus, could be an alternative to the government’s 14-day quarantine on arrival proposal.
Other measures set to be trialled by Heathrow include UV sanitation and new procedures to further reduce contact between people.
Cameras could also be deployed in departures and connection areas if the trial is a success.
Holland-Kaye has also backed the introduction so-called "immunity passports" which he told the broadcaster could be issued to people who have already had Covid-19.
However, he said there would need to be global cooperation on the scheme, and acceptance of the document, in order for it to be a success.
He added he felt flights should restart between "low-risk" countries to boost the economy and help hard-hit sectors like tourism and aviation recover.
