Germs, sometimes known as Bacteria, are alive, but you can’t see them. Bacteria are groups of tiny organisms that have only one cell. They are on the ground, in the air, on your shoelaces, the handle to the refrigerator, the tip of your nose. They are all around us.
Some bacteria can cause diseases but not all of them. Humans actually need some kinds of bacteria to live!
