- Therefore, we define a reservoir as one or more epidemiologically connected populations or environments in which the pathogen can be permanently maintained and from which infection is transmitted to the defined target population.

- Reservoir. The reservoir of an infectious agent is the habitat in which the agent normally lives, grows, and multiplies. Reservoirs include humans, animals, and the environment.
- Portal of exit. Portal of exit is the path by which a pathogen leaves its host. The portal of exit usually corresponds to the site where the pathogen is localized.
- Modes of transmission. An infectious agent may be transmitted from its natural reservoir to a susceptible host in different ways. There are different classifications for modes of transmission.
- Portal of entry. The portal of entry refers to the manner in which a pathogen enters a susceptible host. The portal of entry must provide access to tissues in which the pathogen can multiply or a toxin can act.

We discuss the practical value of different approaches that may be used to identify reservoirs in the field. Keywords: reservoir, epidemiology, pathogen, disease control, transmission. Infectious agents that can infect more than one host species are ubiquitous.

Jul 22, 2022 · A human acting as a reservoir of a pathogen may or may not be capable of transmitting the pathogen, depending on the stage of infection and the pathogen. To help prevent the spread of disease among school children, the CDC has developed guidelines based on the risk of transmission during the course of the disease.
Reservoirs of infection are natural habitats where infectious agents live, grow, and multiply, providing a source of infection for humans and other hosts. These reservoirs can be living organisms, such as animals and humans, or non-living environments, like soil and water.
Jan 15, 2019 · The most applicable and accepted way to investigate and define a reservoir emphasizes the annotation of a target group (Figure 1), which is an explicitly defined population of interest in a dynamic and heterogeneous landscape (for example, humans at the livestock–wildlife–human interface).
In epidemiology, a reservoir is defined as a source or place in which an infectious agent can live and multiply, and from where it can be transmitted to human populations or other susceptible hosts. Reservoirs can be animals, humans or the environment.
