I really dislike disingenuous arguments like this one. Comparing personal choices that wreak health with random tranmission of a highly virulent disease is just dishonest.
I get the sentiment. The overall risk delta is probably astronomical, but I can't control how other people behave if/when they are contagious with something. And as it stands right now, the official line on proper precautions doesn't seem to be sufficient.
Yeah, somebody else's eating/smoking/drinking habits have zero chance of killing me as I travel through airports (unless it's the pilot), somebody infected with this virus on the other hand has a far greater chance of ending my life.
