Infection
Microorganisms are living things that are so small that they can not be seen by the naked eye. When a microorganism causes a disease it is then called a pathogen. A host is a scientific term used to refer to whatever the pathogen is living in. So a host could be an animal, such as a human, or even a plant. An infection occurs once a pathogen enters a host. Disease occurs after infection once the pathogen disrupts homeostasis, or "the balance", in the host's normal functions. The study of this process is known as pathology, and the process of a disease being caused by a pathogen in a host is called pathogenesis.
The pathogen tries to infect the body. The defense mechanism of the body resists the entry of the pathogen. If pathogen succeeds the infection is established and the body becomes sick.
