Some kids think that germs are — bugs — cooties — other gross stuff. Actually, germs are tiny organisms, or living things, that can cause diseases. Germs are so small and sneaky that they creep into our bodies without being noticed.
They are so tiny … you need to use a microscope to see them. When they get in our bodies, they can make us sick!
What do Germs do? Once germs enter our bodies: 1.They snuggle in for a long stay. 2.They gobble up nutrients and energy, and can produce toxins, which are like poisons. 3.Those toxins can cause symptoms of common infections, like fevers, sniffles, rashes, coughing, vomiting, and diarrhea.
