Google search queries track flu spread
we compared these aggregated queries against data provided by the us centers for disease control and prevention, and we found that there's a very close relationship be tween the frequency of these search queries and the number of people who are experiencing flu-like symptoms each week .
the approach, validated against centers for disease control (cdc) flu records, provides timely data that could be two weeks ahead of government figures .
google's philanthropic arm google.org has released a new site that tracks the incidence of flu in the us based on terms used in google search queries .
