Influenza is like a sneaky guest that comes to your body party and makes everyone feel tired and sick.
Influenza, or flu, is a sickness caused by tiny germs called viruses. These viruses are so small, you can’t see them with your eyes, they’re like the dust bunnies under your bed, but even tinier!
When someone with the flu coughs or sneezes, they send these tiny viruses flying through the air. If you breathe them in, they can sneak into your body and start a party inside your nose and throat.
How the Flu Feels
Once the virus is inside you, it starts to cause trouble, your body feels like it’s been running a marathon. You might feel sore, have a fever, or even get a cough that won’t stop. It's like when you’re really tired after playing all day and then get a little hurt, everything feels worse.
But don’t worry! Your body is strong, and with rest and care, it can beat the flu and send those tiny guests packing.
