Google combines Google maps with flu data. Google Flu Trends uses aggregated Google search data to estimate current flu activity around the world in near real-time. Google combines Google search terms with data from the Centers for Disease Control (CDC) to determine where the next flu outbreak might occur. This is now available for 16 additional countries and also the site is available in 37 languages.
Google Flu Trends is based on relationship between how many people search for flu-related topics and how many people actually have flu symptoms. By tracking the popularity of certain Google search queries, now the level of flu activity can be estimated, in near real-time.
Google Flu Trends provides near real-time estimates of flu activity for a number of countries and regions around the world, based on aggregated search queries. Some of these estimates have been validated through comparison with official historical influenza data from the relevant country or region.
