 The infoveillance detects disease outbreaks quicker than traditional public health surveillance systems with the minimal cost involved, revealing the promising results for the future surveillance methodologies . Google Flu Trends Google uses the query information to detect the flu trends and it compares   the results to the countries' official surveillance data . The primary research behind the Google Flu Trend can be found in Ginsberg et al. 's work. In light of evidence  showing that Google Flu Trends was occasionally over-estimating flu rates, researchers have also proposed a series of more advanced and better-performing approaches to flu modeling from Google search queries.

 The infoveillance detects disease outbreaks quicker than traditional public health surveillance systems with the minimal cost involved, revealing the promising results for the future surveillance methodologies . Google Flu Trends Google uses the query information to detect the flu trends and it compares the results to the countries' official surveillance data with the goal of predicting the spread of the flu. In light of evidence showing that Google Flu Trends was occasionally over-estimating flu rates, researchers have also proposed a series of more advanced and better-performing approaches to flu modeling from Google search queries.
