Animal health experts in southern Scotland say they are braced for the Schmallenberg disease to spread.
The virus was confirmed last week for the first time in mainland Scotland when it appeared on a farm close to Dumfries.
The disease, which can lead to birth defects in sheep and cattle, has already appeared in Cumbria.
Vets in Scotland say they will now monitor the illness closely.
