Tracking the Evolution and Spread of the 2009 Influenza H1N1 'Swine Flu' Outbreak
The current swine flu outbreak is being tracked in many different ways. News reports are being aggregated into an overall geographic story about the spread of the virus: see for example the Rhiza Labs page and this Google Maps mashup.
In addition to the tracking of news reports, sequence data are being released at NCBI and GISAID. These data are being tracked and subjected to cutting-edge molecular analysis at the Human/Swine A/H1N1 Influenza Origins and Evolution site.
