Use WheresFlu™ Online to track incidence levels of cold and flu symptoms around the country and keep track of the top 5 affected cities in the nation. Data is provided from SDI (a source used by the Centers for Disease Control and Prevention).
The SDI FAN® program measures weekly activity for cold and flu based upon real-time reports of symptoms. As the longest-running respiratory tracking program in the US, SDI FAN® covers illness levels in 135 regions across the country utilizing panel-member reporting along with patient-specific data. Incidence of illness is categorized as Normal (<3% population affected), Low (3-8% population affected), Moderate (8-14% population affected), High (14-16% population affected), or Very High (>16% population affected). Advanced tracking uses illness status levels to predict change in the affected population for the US nine Census Regions.
