Google FluTrends
What a cool wee application this is. Using the search data from Google, and combining it with geolocation data, they are now estimating flu activity in the US based upon search for flu-related terms that have a good correlation to actual flu activity. What a great mechanism for getting the low-down on flu activity. I wonder if we’d have enough search activity in New Zealand (and indeed for other counties) to be able to use this as an estimator for flu in the future.
