Swine vesicular disease in Great Britain.

The State Veterinary Service in Great Britain has encountered considerable difficulty in eradicating SVD. For the last four years confirmed outbreaks have been mainly confined to one region, linked directly to outbreaks in that region, or have occurred as isolated cases related to the feeding of swill. The surveillance effort to locate subclinical disease has far surpassed that of any other country. There is no doubt that the introduction of SVD into any country which adopts a stamping-out policy for FMD and does not vaccinate, could present similar problems to those experienced by Great Britain.
