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.
