Scientists recently documented that influenza spreads around the world more efficiently in the modern era due to commercial air travel. Symptoms of a pandemic level flu are severe enough that the ill 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 still on a plane, the infected person's cough can spread the virus easily in the enclosed and closely-packed environment.
Which of the following would best minimize the role air travel can play in the spread of influenza ding a pandemic?
(A) installing air filters on systems in the planes to kill any flu virus particles flowing
through the filters
(B) requiring air travelers to receive flu vaccinations far enough in advance of the
trip to provide protection against the disease
(C) refusing to allow children, the elderly, or others who are especially vulnerable to
flu to travel by air during a pandemic
(D) requiring all air travelers to wash their hands before boarding a plane
(E) conducting medical examinations during the boarding process to weed out passengers
with flu symptoms
The OA is B but to me A seems to be a better option.
If the vaccination is received far enough in advance then there is a chance that by the time the traveler board the flight he/she may develop symptoms of flu where as in case air filters are installed near the passenger seats they will effectively kill viruses.
