Germs are more like bugs than dirt because they are microorganisms, or tiny living things. In fact, most germs are so tiny that you need a powerful microscope to see them. Because they are so small, germs are very tricky. They can secretly invade the human body like an invisible army.
The four major types of germs are bacteria, viruses, fungi, and protozoa. They can invade plants, animals, and people, and sometimes they can make us sick. Bacteria (say: BAK-teer-ee-uh) are tiny, one-celled creatures that get nutrients from their environments in order to live.
How do Germs spread? The main way that illnesses like colds and flu are spread is from person to person in the respiratory droplets of coughs and sneezes. Although having some germs on and in your body increases your ability to fight illness, being covered with too many germs is plain disgusting.
