Epizootic
（重定向自Epizootic disease）
In epizoology, an epizootic (from Greek: epi- upon + zoon animal) is a disease event in a nonhuman animal population, analogous to an epidemic in humans. An epizootic may be: restricted to a specific locale (an "outbreak"), general (an "epizootic") or widespread ("panzootic"). High population density is a major contributing factor to epizootics. Aquaculture is an industry sometimes plagued by disease because of the large number of fish confined to a small area.
