The great '08/'09 swine flu bust--and the corresponding great vaccine oversupply--may be easier to avoid during the next potential pandemic, thanks to informatics work underway at Indiana University. Researchers there are studying the interplay of human mobility patterns--like those between local metropolitan commuters and long-range airline travelers--to develop models with enough detail to aid public health emergency decision-makers. Researchers want to learn two things: Whether one mobility scale may be most relevant in defining a global epidemic pattern, and the appropriate level of resolution for such a scale. Announcement
