Sporadic: Isolated cases of lab confirmed influenza in the state; Influenza-Like-Illness (ILI) activity is not increased. Or a lab confirmed outbreak in a single institution (nursing home, hospital, prison, school, etc) in the state; ILI activity is not increased.

Local: Increased ILI within a single region and recent (within the past 3 weeks) laboratory evidence of influenza in that region. ILI activity in other regions is not increased. Or two or more institutional outbreaks (ILI or lab confirmed) within a single region and recent (within the past 3 weeks) lab confirmed influenza in that region. Other regions do not have increased ILI and virus activity is no greater than sporadic in those regions.

Regional: Increased ILI in > 2 but less than half of the regions and recent (within the past 3 weeks) lab confirmed influenza in the affected regions. Or institutional outbreaks (ILI or lab confirmed) in > 2 and less than half of the regions and recent (within the past 3 weeks) lab confirmed influenza in the affected regions.

West Virginia Sentinel Provider Data, 2003-2004 Season

The map below shows West Virginia counties that have enrolled influenza sentinel providers for the 2003-2004 season.
