Question Answer
What is a cold?
  • A cold is a mild viral infection of the upper respiratory system.
  • A cold is caused by a virus, a microbe which cannot live on its own so it infects the cells of other living beings.
  • There are over 200 viruses that can cause a cold, the most common being the rhinovirus.
What is the flu?
  • A flu, like a cold, is caused by a virus.
  • A flu is much more serious than a cold. It is potentially deadly.
  • The flu virus changes often, but comes in three basic forms or strains: A, B, or C.
What are the symptoms?
  • Cold symptoms include runny nose, sore throat, mild fever, mild headache and body aches, sneezing, coughing and congestion.
  • Flu symptoms include many of the same symptoms as a cold, but also high fever, more severe aches and pains, chills and sweats, severe sore throat and fatigue.
  • Fever, chills, severe fatigue and aches are also the symptoms which most distinguish infection by a flu virus from infection by a cold virus.
How do I treat a cold?
  • There is no cure for the common cold. You  can simply ease the symptoms while you have a cold.
  • Get plenty of rest and fluids
Take an Over the Counter medication to make yourself more comfortable by easing symptoms.
How do I treat the flu?
  • Like  the cold, there is no single “cure” for the flu. Look to ease symptoms while you have the flu.
  • Because the symptoms are similar, many of the treatments that work to ease cold symptoms also ease flu symptoms.
  • See a doctor if your symptoms include trouble breathing, faintness or very high fever.
How do I prevent colds and flus?
  • A good, healthy lifestyle including adequate sleep, moderate exercise and a balanced diet will help keep you and your immune system strong.
  • Wash your hands often and avoid touching your mouth and nose with your hands.
  • Avoid crowded places during the peak of cold and flu season.
What should I know about the flu vaccine?
  • The flu vaccine comes in two forms: injection and nasal mist.
  • The vaccine is not 100 percent effective in preventing the flu, but is generally believed to be about 70 to 90 percent effective.
  • Because the flu virus is constantly changing, you must get the flu vaccine every year, preferably at the beginning of flu season, in order for it to be most effective.
