“Despite all the intervention measures that the U.K. had in place to try to stop people with the illness getting on flights to the U.K., almost every single plane we tested contained the virus, and most of the terminal sewers, too,” said researcher Davey Jones, a professor in the School of Natural Sciences at Bangor University in Wales.

“That might have been because people developed symptoms after testing negative; or were evading the system, or for some other reason,” Jones said in a university news release. “But it showed that there was essentially a failure of border control in terms of COVID surveillance.”
