There's a list of flights over at Penny Arcade of those with confirmed cases so, if you attended, make sure you check that out. But whether or not yours appears there, you need to keep an eye on your health, okay? Don't freak out, just be smart.
Important note for non-PAX attendees only: Okay, we're going to have to be smart about this thing if we're going to survive it. If you know someone who went to PAX, it's very sad, but they're dead now. You hear us? DEAD. We don't care if your own brother is banging down your door asking for NyQuil, you just keep telling yourself, "That must be the wind. It can't be Griffin, because he's dead."
Also, invest in power armor.
