What is COVID-19?

COVID-19 is a bug that makes people feel sick, just like when you get a cold or a sore throat.

Imagine your body is like a castle with guards, the immune system, who protect it from germs, which are tiny bugs that can make you feel unwell. Normally, those guards know how to fight off most germs, but sometimes they come across a new kind of germ they haven’t seen before.

That’s what happened with COVID-19. It's a kind of virus, like a sneaky little spy that slips into your body through the air when someone coughs or sneezes. Once inside, it starts multiplying and makes you feel tired, sore, or even out of breath.

Think of germs as tiny pieces of confetti flying around in the air. When you breathe them in, they go into your lungs like a little party, but instead of fun, it feels more like a big sneeze or cough!

Sometimes, people who have COVID-19 don’t feel sick at all, which means they can pass it on to others without even knowing it. That’s why it's important to wash hands and wear masks, just like cleaning up after a messy party!
