Flutrack is a system that detects influenza symptoms by processing and displaying influenza related Twitter messages. Flutrack platform gathers and visualizes tweets every 20 minutes in real time. This open platform and its API allow users and developers to extend this project and take influenza detection to higher levels. The platform could work not only with Twitter but with any data provider. For monitoring purposes, Flutrack gathers flu related tweets for the entire world using the Twitter API. Since the above procedure is complete, the system visualizes and updates tweets every 20 minutes. The Flutrack open-platform differs from similar tracking services in that it extracts and processes flu related data in real time, without interruption. == Feasibility of monitoring influenza == Influenza, or flu, is a viral infection that affects mainly the throat, nose, bronchi and occasionally lungs. It is considered one of the most common human infectious diseases. Seasonal influenza epidemics are a major public health concern, causing tens of millions of respiratory illnesses and 250,000 to 500,000 deaths worldwide each year. Early detection of disease activity, when followed by a rapid response, can reduce the impact of both seasonal and pandemic influenza. Influenza differs from the common cold as it is caused by a different group of viruses, and its symptoms tend to be more severe and to last longer. Infection usually lasts for about a week, and is characterized by sudden onset of high fever, aching muscles, headache and severe malaise, non-productive cough, sore throat and rhinitis. Symptoms usually peak after two or three days. Self-diagnosis of influenza is common among the general public. The best predictions for influenza are cough and fever, since this combination of symptoms has been shown to have a positive predictive value of around 80% in differentiating influenza within a population suffering from flu-like symptoms. 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「Flutrack」の詳細全文を読む スポンサード リンク
