Viruses are not living pathogens, they are "organisms" with the ability to duplicate themselves ~ but only if they have a living host to provide the energy and materials for the duplication process. Different viruses use different hosts and most of the time they don't cross over species for hosts, but some do. The H1N1/09 virus was able to mutate from a strain that pigs got to a strain more targeted toward people. Other viruses use plants and other animals for hosts.
The short explanation of how this happens is:
- Virus is in the environment
- Host is exposed to the virus in the environment
- Some virus particles are able to attach to the cell walls of the cells of the host.
- The virus connects to the center of the cell and injects genetic material that the virus uses to instruct the host cell how to make virus duplicates
- Host makes new viruses
- Virus duplicates get out of host cells and spread to infect more hosts
