Influenza (flu)

Influenza (flu)

You’ll fall ill with influenza (better known as the flu) when the virus infects your nose, throat and lungs. Influenza symptoms will be sudden, last up to seven days and can be mild to miserable. You may have a fever, chills, sore throat, sinus congestion, muscle aches or fatigue. You’re most likely to get influenza from someone who is ill, which means you can also spread it. And that’s why it’s important you’re vaccinated against influenza each year at a flu shot clinic near you.

Your best protection
Flu vaccination

The flu vaccine is the best prevention against influenza. We recommend everyone 6 months and older get the vaccine, but it is especially important to protect yourself with the vaccine if you’re:  

  • A child 
  • Pregnant  
  • Age 50 or older  
  • Have chronic health conditions such as asthma, diabetes or heart disease 
  • Live in a nursing home 
  • Work in healthcare
