Germs

Germs are found all over the world, in all kinds of places. The four major types of germs are bacteria, viruses, fungi, and protozoa. They can invade plants, animals, and people, and sometime can make us sick.

What Do Germs Do?

Once germs invade our bodies, they snuggle in for a long stay. They gobble up nutrients and energy and can produce toxins, which are proteins that act like poisons. Those toxins can cause symptoms of common infections, like fevers, sniffles, rashes, coughing, vomiting, and diarrhea.
