The flu, also called influenza, is a disease cause by the influenza virus.
The number of influenza cases so far this fall is outrunning last year's pace by more than 3-to-1, San Diego County health officials reported today. No outbreaks were declared.

Everyone older than six months old should get the vaccine, including pregnant women. The health unit then coordinates distribution with pharmacies, family doctors and nurse practitioners.
