Portugal has reported the presence of the Bluetongue virus serotype 3 in three sheep farms in the Évora Region, with symptoms and mortality observed in animals. Additional suspect cases are under investigation, leading Spain to temporarily halt the movement of susceptible animals from Portugal. In response, Portugal is preparing an emergency vaccine bank against this serotype, which was first detected in the Netherlands in October 2023 and has since spread across Europe and North Africa, causing severe symptoms in sheep and milk production issues in cattle.
