epizootic
C1/C2Technical/Scientific
Definition
Meaning
An outbreak of a disease affecting many animals of one kind at the same time within a particular region.
It describes both the event (the outbreak) and the disease itself, analogous to an epidemic but in non-human animal populations. Can also be used figuratively to describe something that spreads rapidly through a group, though this is less common.
Linguistics
Semantic Notes

It is a countable noun when referring to an event ('an epizootic occurred'), and a non-countable adjective when describing the disease ('an epizootic disease'). The term implies a rapid spread and a defined geographical area.

FAQ
Frequently Asked Questions
No, by definition, 'epizootic' refers to diseases in non-human animal populations. For humans, the correct term is 'epidemic' or 'pandemic'.
An epizootic is an outbreak affecting many animals in a specific region. A panzootic is an epizootic that spreads across an exceptionally large area, such as multiple continents or worldwide, analogous to a pandemic in humans.
No, it is a low-frequency, specialized term used almost exclusively in veterinary, agricultural, and ecological contexts. The average person will rarely encounter it.
The direct epidemiological opposite is 'enzootic', which describes a disease that is constantly present in an animal population within a specific geographic area, but at a low, predictable level.
