In the last couple of weeks we’ve had several posts about Google. We discussed using Google Analytics with Flash, about how in Argentina Google being forced to censor search results and a little further back, about tracking regional search engines in Google Analytics. By far the most interesting function that we’ve discovered Google has, is to track flu trends. Seriously.
On the 21st Novemeber, in a follow up to an early blog post, the Google team published an academic paper in Nature, explaining the science and methodology to track Flu Trends using Google Trends. Initially this seems absolutely absurd; to be able to track something so clearly organic (and offline) as the Flu, using a search engine.
Well, we can. Last year, a team of software engineers began to explore the possibility of using Google Trends to look beyond simple epolitical or technology trends, and accurately model real-world phenomena through the search patterns of individuals. Considering the impact that disease has on people, globally, they decided to focus their efforts on infectious diseases, which are responsible for millions of deaths around the world each year.
The most obvious was of course, influenza, commonly known as the flu.
So in coordination with the U.S. Centers for Disease Control and Prevention (CDC), the team used aggregated search query data and data provided directly by the CDC to investigate if there is a relationship between the frequency of search queries and the number of people who get the flu each week.
Sure enough the results were staggering. The correlations were there and Google was able to launch Google Flu Trends, providing up-to-date flu activity data for each of the 50 states in the U.S. Unfortunately the tool is limited to the United States but hopefully with future participation from similar organizations in other countries, it can be expanded.
Another small step for digital, another giant leap for…… digital.
