The term that describes the process by which pathogens are transmitted between the environment and poultry populations is horizontal transmission. This process refers to the spread of infectious agents from one individual to another, or from the environment to animals, within the same generation. In the context of poultry, horizontal transmission can occur through direct contact with contaminated surfaces, water, feed, or other infected birds.

For poultry, understanding horizontal transmission is crucial because it helps in implementing biosecurity measures to prevent disease spread. This includes practices such as controlling the movement of equipment and vehicles, maintaining clean living environments, and monitoring the health status of existing flocks to minimize the introduction of pathogens from the environment.

Other terms like vertical transmission refer to the transfer of pathogens from parent to offspring, which typically occurs during reproduction, while environmental transmission may be considered a broader concept but does not specifically define the direct interaction paths like horizontal transmission does. Incubation transmission is not commonly used in the context of pathogen spread but relates more to the period during which a pathogen develops within a host before symptoms appear. These distinctions are important for understanding disease dynamics in poultry populations.
