Internet data sources for disease surveillance: Assessment of suitability

This assessment evaluates 34 internet activity data sources for use in disease surveillance. Our goals are to (a) understand the available data on internet usage and activity well enough to (b) identify real-world internet data sources that can be used both for evaluating our theories of disease surveillance and building operational internet data-based disease surveillance systems. The assessment (pdf) and raw data (excel spreadsheet) are attached.
