This is a [[:Category:Poxviridae|pox virus]] that affects cattle, cats and humans, therefore it is zoonotic. It is a disease of management in dairy cattle, with poor hygiene of milking equipment thought to contribute largely to the spread of infection. The virus is transmitted by direct contact either from milking equipment in cattle or from rodents (which act as a reservoir) in cats. The disease is now uncommon due to excellent hygiene protocols on farms.

On the cow, lesions develop on teats and udder and appear as shallow, pus-filled, crate-like ulcers. They are flat, red and glistening in some cases. These same lesions are found most commonly on the paws, head and lips of cats. Cats can also be infected with a '''respiratory''' form, where proliferative and necrotic lesions can be seen in the mouth and lead to the upper respiratory tract. This form is invariably fatal.
