Influenza (Flu)

Influenza is a respiratory illness that is common between October and March every year. The peak of influenza season is most often in February, but it has seen peaks as early as December. Symptoms of influenza include: 

  • Fever/chills
  • Cough
  • Sore throat
  • Runny or stuffy nose
  • Body aches
  • Headaches
  • Tiredness
The best method for preventing infection with influenza is to get vaccinated. The vaccine is not 100% effective, but getting vaccinated will not only reduce the chances of infection, but can also reduce severity of the illness if it is contracted. It is important to note that there is a 14 day period between the time that the vaccine is administered and when it is fully effective (CDC, 2017). Prevention measures include: 

  • Vaccination
  • Regular hand-washing 
  • Avoid touching your face
  • Avoiding people who are ill
If you do contract influenza please remember that it is very contagious and that the best things you can do if you become ill are:

  • Remain home when you are ill 
  • Keep your children home if they are sick 
  • Cover your cough
  • Wash your hands
