FIGURE 1: Proof of Concept Correlation Between Internet Search Query Data and Actual Influenza-Like Illness. Search query results for influenza-related terms are correlated with actual ILI-related physicians’ office visits as reported by the Centers for Disease Control over a five-year period from April 2012- April 2017. NOTE: NOT TO SCALE. Results for “flu” and “flu shot” are exhaggerated to share the same y-axis values.
