Steps are required for a pathogen to infect a novel host species.
- A pathogen is defined as an organism causing disease to its host, with the severity of the disease symptoms referred to as virulence.
- The pathogens can be viruses or bacteria. If the host is humans then these pathogens can enter through nose, sputum, yes or any cut wounds.

- The pathogens after multiplying, increases in number and damages tissues and organs of the host thereby causing diseases.
