reservoir host. Type:Term. Definitions. 1. the host of an infection in which the infectious agent multiplies and/or develops, and on which the agent depends for survival in nature; the host essential for the maintenance of the infection during times when active transmission is not occurring.
In infectious disease ecology and epidemiology, a natural reservoir, also known as a disease reservoir or a reservoir of infection, is the population of organisms or the specific environment in which an infectious pathogen naturally lives and reproduces, or upon which the pathogen primarily depends for its survival. A reservoir is usually a living host of a certain species, such as an animal or a plant, inside of which a pathogen survives, often without causing disease for the reservoir itself.
