Statewide Temporal Trend of Influenza-Like Illness by MMWR Week

The figure below displays the number of influenza-like illness cases reported during the 2004-05, 2005-06, 2006-07 and 2007-08 influenza seasons.  Illness is defined as fever > 100˚ F AND cough and/ or sore throat without another identified cause.  ILI can be caused by a variety of respiratory viruses, so data should always be interpreted in the context of laboratory data.  ILI cases are reported by physicians to local health departments.  Local health departments report the data weekly to the state.
