Influenza

influenza

Influenza is transmitted by direct and indirect contact via respiratory droplets from coughing, sneezing or from just shaking hands.  The incubation period is several days and contagiousness can last as long as a week after the symptoms begin.  The best way to limit its spread is by frequent hand washing with soap and water for 15 to 20 seconds and by limiting close face to face contact with others when symptoms are present.  It is very important to know the difference between the common winter cold and influenza.  As opposed to a common cold, influenza has these distinguishing characteristics:

  • Very sudden onset
  • Fever
  • Aches
  • Sore throat

At the onset of influenza symptoms people often say they feel as if they had been “run over by a truck.”

The treatment for influenza is mostly symptomatic care:  plenty of rest, Tylenol or Advil (ibuprofen) for fever and aches, and maintaining adequate liquid intake.  There are drugs such as Tamiflu, available from a doctor which if taken within the first 48 hours of influenza symptoms may shorten the course of the illness by several days.  These are recommended for the elderly or chronically ill patients with influenza symptoms.

Being immunized by a flu shot significantly lessens one’s chance of getting the flu.  But as with any treatment there is no guarantee of 100% success.  One can still get a bad viral upper respiratory infection during the winter months even after the flu vaccine. Most people who receive the flu shot have no bad reaction to it.  Some people may experience redness and swelling at the injection site lasting a few days.  One cannot get the flu from a flu shot because it is made from a deactivated dead virus.  The benefit of the flu shot far outweighs the minimal risks.  Although the ideal time for a flu shot is from mid-October through November, the flu season can extend through May.
