Infoveillance is the type of syndromic surveillance that utilizes the online contents. The term was coined by Gunther Eysenbach in 2004 for the first time along with Infodemiology The work of Gunther Eysenbach, which utilized the Google Search queries, had led to the birth of Google Flu. Other than Google search engines have also been used. Later other researchers utilized other social media such as Twitter to find the disease outbreak patterns. 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 Trend== 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 is found here. 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 modelling from Google search queries. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Infoveillance」の詳細全文を読む スポンサード リンク
