The swine flu panic is going to be electronically mediated in a way no previous threat to public health has been. Flu information sites have sprung up in which news stories and data are being aggregated — the Flu Wiki Forum and Wikia’s Flu Wiki, which has a nice Google map mashup showing where the cases are.

The intrepid and slightly paranoid (I know he won’t mind my saying so) Chris Soghoian has another angle in his post on Swine Flu and the Threat to Privacy. Eight students from one New York City school are suspected of having contracted this strain of influenza while on a school trip to Mexico. If they were suspected terrorists, the government would by this time have gotten their cell phone carriers to turn over lists of all the people they had telephoned recently. It would be easy enough — yes, this is true — to ask the carriers to turn over lists of the names of all people with cell phones that had been within 100 feet of one of the students’ cell phones during their Mexico trip or thereafter. Now stored cell phone geolocation information isn’t that precise, so the data request would probably yield a lot of false positives — people in the same general area but not that close.

The information may well have been collected already. And that may well be exactly the right thing to do. After all, the first rule of epidemics is that controlling them becomes exponentially harder if they are allowed to spread; you don’t wait until they are severe before reacting. Do we know? If the data has been collected, do we have any confidence that it isn’t going to be repurposed, and that it will be discarded eventually?
