I was wondering the same thing. Plane from Brussels, reports are saying the father and daughter are likely from Liberia, they're exhibiting "flu like symptoms" and the plane was boarded by officials in Hazmat suits.
How are they ruling out Ebola already?
That's easy... same way the economy is better, the war on terror has been won, healthcare in the US is fixed, we have the most transparent and ethical admin in history, etc.
You simply get the government to declare something to be a fact, and voila...it's now a fact.
