Scientists recently published that influenza spreads around the world more efficiently in the modern era due to commercial air travel. Flu symptoms are severe enough that the sick would likely cancel or reschedule air travel, but an infected person can travel across the globe before the first signs appear. Further, if symptoms develop while someone is on a plane, the patient’s cough can spread the virus easily in an enclosed and closely packed environment. Which of the following would best minimize the role air travel can play in the spread of influenza during a pandemic?
