Why are some people experiencing 'long COVID' symptoms for months?

Some people feel tired or have trouble breathing for months after having COVID-19, kind of like how you might feel sore and sleepy after a really long playdate.

Imagine your body is like a toy that needs time to recharge. When you get sick, it's like the toy gets shaken up, it loses some of its energy. For most kids, the toy charges back up in a few days or weeks. But for some people, the toy takes longer to charge again, and they feel tired or out of breath until it’s fully charged.

Sometimes, when your body is fighting COVID-19, it can get a bit confused. It might send extra helpers (like little soldiers) to fight off the virus. After the battle is over, those helpers might still be running around, making you feel a bit grumpy or tired for longer than usual.

It’s like when you have too many friends coming over at once, your house gets messy, and it takes time to clean up after everyone leaves.
