| + | *Occurs in horses aged 1-3 years |
| − | == Introduction ==
| + | *Muzzle, oral cavity |
| − | | + | *Spread by direct contact |
| − | Equine papillomas are small, warts that occur on the muzzle and in the oral cavity of young horses. They are not to be confused with [[sarcoids]], that are a locally aggressive tumour of the integument and may have a similar appearance.
| + | *Virus persists giving life long immunity and antibody-detection |
| − | | + | *Usually resolves spontaneously but can be treated by laser or cryo-freezing |
| − | The virus affects the stratified squamous and/or mucosal epithelium and grows slowly - lesions may take weeks to appear. The viruses in this family are species specific and transfer is usually by direct contact, however, the virus can survive for long periods of time in the environment and can also be spread by fomites. The virus persists even when warts have resolved, giving life long immunity and antibody protection.
