Google tool uses search terms to detect flu outbreaks
If you have a fever, headache and runny nose, you might go to Google and type the words “flu symptoms” to see whether you’ve come down with influenza.
Google knows that you might do something like that, and it also knows which U.S. state you’re in. Now, it’s putting that information together in a tool that Google says could detect flu outbreaks faster than traditional systems currently in use.
Google’s new public health initiative, Google Flu Trends, looks at the relative popularity of a slew of flu-related search terms to determine where in the U.S. flu outbreaks may be occurring.
