Bluetongue disease, caused by serotype 3 of the bluetongue virus, has been detected in three sheep farms in Évora, Portugal, leading to concerns for the health of flocks in the Iberian Peninsula, particularly in Almería, Spain. To prevent the spread of the disease, which can cause up to 25% mortality in infected animals, the Spanish government is expediting the distribution of vaccines and has temporarily halted the movement of cattle and sheep between Spain and Portugal. The disease, which was first identified in Tunisia in 2018 and has since spread across Europe, does not affect humans.
