Super-sniffing dogs could shorten Covid testing lines in airports: Study

Two dogs could accurately scan 300 plane passengers in about half an hour as part of a screening strategy, scientists found.

Two dogs could accurately scan 300 plane passengers in about half an hour as part of a rapid screening strategy, scientists from the London School of Hygiene and Tropical Medicine said in research published Monday. Then only the people selected by the dogs would need to undergo a PCR test.
