Imagine tiny, invisible soldiers called bacteria invading your body. Some of them are like troublemakers who take over your cells and make you feel sick. When they multiply and spread, your body gets confused and starts fighting back, that’s why you get a fever or a cough.
How It Works
Bacteria can enter your body through your mouth, nose, or even tiny cuts on your skin. Once inside, they start eating the food in your cells or making your cells work overtime to produce more of them. This makes your body feel weak and tired, like when you're sick.
Examples
- Germs from the playground can make you feel sick after playing with your friend.
- A bad tooth can let germs go into your body and cause an infection.
- Sometimes, eating food that wasn’t washed properly makes you get a tummy ache.
