Long COVID is when your body still feels tired or unwell even after you've mostly recovered from a cold-like illness called COVID-19.
Imagine you're playing with your favorite toy, and then you get a little hurt. You rest for a while, and soon you’re back to playing like nothing happened. But sometimes, the hurt lingers, it might make you feel sleepy or dizzy even when you're not playing anymore. That's kind of what long COVID is like.
How it works
When you get COVID-19, your body fights off the virus, just like when you fight off a cold. Most people get better in a few weeks. But for some, their body keeps feeling like it’s still fighting, even if the virus isn’t there anymore.
It's like having a tiny robot inside you that’s still working hard, even though the job is done. This can make you feel tired, short of breath, or have headaches more often than usual.
Why scientists are watching it
Doctors and scientists are studying long COVID to understand why some people feel better and others don’t, just like how you might study why your friend gets a cold every winter, but you never do.
Examples
