Long COVID symptoms stick around because your body is still cleaning up after the virus.
Imagine you spilled a big pile of Legos all over the floor. You cleaned them up quickly, but some tiny pieces are still stuck in your carpet, they’re not hurting you, but you can feel them when you walk barefoot. That’s like what happens to some people after they recover from COVID.
Like a Cleanup Crew Still Working
Your body has special workers called immune cells that fight the virus. After the virus is gone, these workers keep cleaning up the mess, little pieces of the virus and damaged cells. Sometimes this cleanup takes longer than expected, especially if your body had to work really hard to beat the virus.
Some People Have More Mess to Clean
Just like some kids have bigger Lego piles to clean, some people’s bodies have more mess to deal with. That means their immune system might be busy for weeks or even months after they feel better, which is why long COVID symptoms can stick around.
Examples
- An athlete can't return to training because of ongoing chest pain and shortness of breath.
