ABSTRACT
Sheep pox and goat pox are infectious viral diseases that affect ovine and caprine animals and are caused by two viruses of the family Poxviridae, genus Capripoxvirus. Sheep pox has been traditionally endemic in Africa, the Middle East, and several Southeast Asian countries, but it is considered a transboundary disease capable of affecting previously free countries epidemically. It is a disease of compulsory immediate notification to the World Organization for Animal Health (WOAH) and the European Union (EU). On 19 September 2022, the disease reemerged in Spain, which had been free of it since 1968, causing a total of 30 outbreaks until 17 May 2023, when the last outbreak of the disease was reported. The control and eradication measures implemented were those laid down in EU legislation, based on the total stamping out of positive herds, zoning and restriction of movement, and strengthening of biosecurity and passive surveillance. This manuscript describes the outbreak, as well as assesses the challenges and lessons learned in relation to its management, with the aim of helping in the effective management of future outbreaks of this disease.
