Epizootic
In epizoology, an epizootic (or epizoötic, from Greek: epi- "upon" + zoon "animal") is a disease event in a nonhuman animal population analogous to an epidemic in humans. An epizootic disease (or epizooty) may occur in a specific locale (an "outbreak"), more generally (an "epizootic"), or become widespread ("panzootic").
