Decontaminating a chair isn’t “causal contact”? Then what is casual contact, in your opinion? And if someone can pick up this disease by touching an object that was touched by a sick person (supposedly, it can live on a surface for many days), what makes you think it can’t live in the air when someone coughs or sneezes in your face?[/quote]

Decontaminating a chair, if it’s full of blood, is not casual contact.

A chair with blood on it is more than just “an object that was touched.” It’s an object that has a large amount of bodily fluids on it.

Science.

Edit: After further research, apparently it might be possible to get it if someone sneezes directly into your face and gets enough fluids in your eyes or mouth or nose. But that’s not the same as the virus being truly airborne, and it’s not an easy- or common-enough method of transmission to result in a widespread outbreak.
