A new update from those behind last week's Penny Expo has admitted that they have received reports of a number of swine flu cases from the big games event.

Apparently, 15 flights to and from Seattle contained PAX attendees who it is later believed were diagnosed with the illness.

The list of flights is available on the Penny Arcade website.

This from PA's Robert Khoo, speaking to Kotaku: "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."
