A reservoir is the primary habitat in the natural world from which a pathogen comes.
An organism that causes the disease is called a pathogen. Your body is already teeming with bacteria. However, these organisms only become an issue if your immune system is compromised or if they are able to get into an area of your body that is typically sterile. Different from other organisms, pathogens can spread disease once they enter the body. A host is all that a pathogen requires to grow and survive.
The pathogen enters a host's body, avoids the immune system's defenses, and uses the host's resources to replicate before leaving and infecting a new host. Depending on the type, there are various methods by that pathogens can be spread. They can be transmitted by skin-to-skin contact, biological fluids, airborne particles, feces, touching a surface, and more. The reservoir is any population of organisms (or any environment) that harbors the pathogen and transmits it to the target population.
