enzootic disease

Enzootic diseases are animal diseases that are peculiar to or constantly present in a specific locality. These diseases are also referred to as endemic diseases and typically reflect a stable relationship between the causative agent and the affected animals. Unlike sporadic diseases that appear only occasionally, or epidemic (epizootic) diseases that occur at higher than normal rates, enzootic diseases are a consistent feature of a particular area. The study of these diseases falls under epidemiology, which examines the interactions between organisms and their environments as they relate to disease presence in animal populations. Epidemiologists aim to understand the factors contributing to disease, including environmental and host factors, and to control them by modifying the environment.12
