Question: Where do germs come from?

Germs are actually living things found all over the world. There are 4 types of germs: bacteria, viruses, fungi, and protozoa. Because they are so tiny, they can get inside our bodies and make us sick. But what exactly can they do?

• Bacteria: They can reproduce inside or outside the body. Some infections bacteria cause include sore throats, ear infections, tooth cavities, chest infections, and pneumonia.
• Virus: They can only live for long while inside a living thing and take nutrients from bigger living things. Some diseases viruses caused: chickenpox, measles, the flu, and many other diseases. Because some viruses can live for a while on something like a doorknob or countertop, be sure to wash your hands regularly!
• Fungi: These are plant-like living things that love warm, damp places and take nutrients from bigger living things. They often cause itchy skin rashes like tinea (athlete’s foot) and ringworm.
• Protozoa: These organisms love moisture and spread disease through unclean water. They can  cause tummy problems like nausea (feeling like you need to be sick), belly pain and diarrhea.

If you do get sick, a doctor can look at what’s wrong with you, and look at your blood in a laboratory to see what is making you sick and figure out how to make you better.

The good thing about all these yucky germs is that we can protect ourselves really easily. Wash regularly with soap and water (especially after doing anything dirty, and before eating), and then dry yourself thoroughly. Always cover your mouth when you cough or sneeze and throw the germ-covered tissues away. Then look after your body with food and exercise so it has the best chance of fighting off any germs.

By the way, did you know there are even a few bacteria that are good for our bodies? They live in our bellies and help digest food!
