Cell phones help track flu on campus. Duke Today, August 18, 2015. New methods for analyzing personal health and lifestyle data captured through smartphone apps can help identify college students at risk of catching the flu. With help from a mobile app that monitors who students interact with and when, researchers have developed a model that enables them to predict the spread of influenza from one person to the next over time. Unlike most infection models, their approach gives a personalized daily forecast for each patient. Picked up by Time Warner Cable News, WRAL, Futurity and the Huffington Post.
