Levels Of Geographic Spread: CDC Guidelines

No Activity: No laboratory-confirmed cases of influenza and no reported increase in the number of cases of influenza-like illness (ILI).
Sporadic: Small numbers of laboratory-confirmed influenza cases or a single laboratory-confirmed influenza outbreak has been reported, but there is no increase in cases of ILI.
Local: Outbreaks of influenza or increases in influenza-like illness cases and recent laboratory-confirmed influenza in a single region of the state.
Regional: Outbreaks of influenza or increases in influenza-like illness and recent laboratory confirmed influenza in at least two but less than half the regions of the state with recent laboratory evidence of influenza in those regions.
Widespread: Outbreaks of influenza or increases in influenza-like illness cases and recent laboratory-confirmed influenza in at least half the regions of the state with recent laboratory evidence of influenza in the state.

The best way to avoid  getting the flu is getting a vaccine.
