List of infectious sheep and goat diseases

Sheep and goats are both small ruminants with cosmopolitan distributions due to their being kept historically and in modern times as grazers both individually and in herds in return for their production of milk, wool, and meat. As such, the diseases of these animals are of great economic importance to humans.
