The PAX twitter feed‘s confirmed that swine flu cases were present at the show.
A list of 15 flights – both from Seattle and ongoing connections – that contained attendees carrying the illness is now up on the Penny Arcade homepage.
Kotaku has a quote on the outbreak from Robert Khoo of Penny Arcade:
“This is the real thing. If you get this number of people together in this close a proximity it is the perfect storm for these kind of wild fire virus spreads. We just want to make sure everyone is informed.”
