The Flu Illness Tracker is an app designed by Marshfield Clinic Research Foundation in which users record illness symptoms and the duration of the illness for members of their household. Researchers then use the information to better understand the flu and the effectiveness of the flu vaccine. To use the app and have information recorded, you must be part of a research study conducted by the Foundation.
