So everybody exposed gets sick? If you are "infected", I will give you a hug. Real world experience trumps your $ci€nc€. You live in fear, I live in peace. A little bit of $ci€nc€ gives humans a false sense of certainty when it looks at a small fraction of the whole picture, in isolation, and are "certain" of their conclusion.
That aside, that wasn't the point. If you search fot something and the top result doesn't acknowledge that the something is something, right or wrong, it's usability is questionable.
