A microbe is a tiny organism living in your body, and in the body of almost every living creature. Microbes are actually good for you. They keep you skinny by boosting your metabolism rate. They also fight disease just by taking up space that bacteria would normally inhabit.
The four major kinds of infectious diseases are viruses, bacteria, fungi, and protozoa. A virus is a form of bacteria that draws nutrients away from your body, leaving you sick. Bacteria are tiny microscopic, very simple, cells that live everywhere. Some are harmless, but some are viruses that can leave you sick for a long time. Fungi are a group of bacteria. A lot of fungi can be dangerous, and even deadly, but some are healthy, like non-poisonous mushrooms. Protozoa are not always good. They eat bacteria, which is a good thing and a bad thing, because they eat the bad bacteria, which is a good thing, but they also eat the good bacteria, which is a bad thing.
Infectious diseases are transmitted in several different ways. They can be transmitted from animals to humans, and from humans to other humans. They can be in one person, who drinks out of a cup of water, but also leaves their saliva on the cup. If another person drinks out of that cup, they can pick up the disease in the other person’s saliva. They can also be transmitted when mosquitos bite you. Some mosquitos have a disease in their blood called malaria. When they bite you, their saliva, along with the disease, is transmitted into your blood stream. Household animals can also give you diseases. If a cat or dog gets some sort of disease on its claws, and then scratches you, that would also transmit the disease into your blood stream. If a baby is sick and bites you, and breaks the skin, the disease can get under your skin.
