What Is The Flu or Influenza-Like-Illness (ILI)?

Influenza ("the flu") is caused by viruses that infect the nose, throat and lungs.  The virus we usually face is referred to as Seasonal Flu. Influenza-like-illness is defined as fever (temperature of 100°F or greater) and a cough and/or sore throat in the absence of a KNOWN cause other than influenza.

The flu usually spreads through the air from person to person when an infected person coughs, sneezes or talks.  When these viruses enter the nose, throat, or lungs of a person, they begin to multiply, causing symptoms of the flu.  Unlike the common cold, the flu can cause serious illness and can be life-threatening, especially for certain people with chronic health conditions.

The best way to prevent the flu is to get a flu shot.

To help prevent the spread of illness from person to person:

  • Cover your cough.
  • Wash your hands often and well.
  • Keep  yourself healthy with rest, exercise, and eat healthy, vitamin-rich foods.
  • Drink plenty of water and other healthy fluids.
  • Stay home if you get sick.
  • Avoid close contact with sick people.
