The flu is like when tiny, invisible bugs called viruses sneak into your body and throw a party. But it’s not a fun party; it’s messy and makes you feel tired and icky. These viruses are like little pirates that board your ship (your body), and they start causing trouble. They make you feel hot, like when you have a fever, and sometimes they give you the chills, like when you’re really cold.
Imagine your body is a castle, and the flu viruses are naughty knights trying to get in. Your body has guards called immune cells that fight to keep them out. But sometimes the naughty knights sneak past the guards and make you feel sick. When this happens, you might cough, sneeze, or have a runny nose because your body is trying to get rid of the bad guys.
Think of the flu like a storm that makes you feel yucky. You might want to stay in bed with a warm blanket and drink lots of water or juice. The good news is your body is a superhero that will fight the flu and help you feel better soon. Just like any storm, it will pass, and the sun will shine again.
