PMDC Verified Question 23 of 24
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 air travel, but an infected person can travel across the globe before the first signs appear. Further, if symptoms develop on a plane, coughing spreads the virus easily in an enclosed environment.

Which of the following would best minimize the role air travel plays in spreading influenza during a pandemic?
A
Refusing to allow children, the elderly, or others who are especially vulnerable to travel by air.
B
Requiring all air travelers to wash their hands before boarding a plane.
C
Requiring air travelers to receive flu vaccinations far enough in advance of the trip to provide protection.
D
Conducting medical examinations during the boarding process and prohibiting passengers with flu symptoms from flying.

Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Conducting medical examinations during the boarding process and prohibiting passengers with flu symptoms from flying.
Concept: Disease Vector Mitigation.

Formula: N/A

Solution: Screening passengers during boarding and isolating symptomatic individuals prevents symptomatic transmission in enclosed aircraft environments.

Why other options are incorrect:

• Option B: Hand washing alone does not block aerosol airborne transmission from coughing.
