In October 2016 the UK government ran a national pandemic flu exercise, codenamed Exercise Cygnus. The report of its findings was not made publicly available, but the then chief medical officer Sally Davies commented on what she had learnt from it in December 2016.
“We’ve just had in the UK a three-day exercise on flu, on a pandemic that killed a lot of people,” she told the World Innovation Summit for Health at the time. “It became clear that we could not cope with the excess bodies,” Davies said. One conclusion was that Britain, as Davies put it, faced the threat of “inadequate ventilation” in a future pandemic. She was referring to the need for ventilation machines, which keep oxygen pumping in patients critically ill with a respiratory disease such as coronavirus.
