Policy be complicated:

The day after that Frieden was asked during a press conference if you could contract Ebola by sitting next to someone on a bus—a question prompted by a statement from President Obama the week before, when he declared that you can’t get Ebola “through casual contact, like sitting next to someone on a bus.”

Frieden answered: “I think there are two different parts of that equation. The first is, if you’re a member of the traveling public and are healthy, should you be worried that you might have gotten it by sitting next to someone? And the answer is no. Second, if you are sick and you may have Ebola, should you get on a bus? And the answer to that is also no. You might become ill, you might have a problem that exposes someone around you.”
