SARS-CoV-2 is like a tiny intruder that can make you feel sick if it gets inside your body.

Imagine your body as a castle, and your cells are little rooms inside the castle. SARS-CoV-2 is like a sneaky visitor who finds a way to slip through the gates of the castle, the cells, and start making copies of itself in those rooms. That’s how it spreads from person to person.

SARS-CoV-2 uses something called spikes, which are like tiny hooks on its surface. These spikes grab onto a special door in your cells, called the ACE2 receptor. Once it gets inside, it starts multiplying, just like how you might copy a drawing with crayons and give it to your friend.

Once SARS-CoV-2 has made lots of copies of itself, it can make your body feel tired, coughy, or even cause a fever. It's like when you have too many toys in one room, things get messy, and the castle (your body) starts to feel overwhelmed.

But don’t worry! Your immune system is like a group of brave knights who come to fight off these tiny invaders.
