Clinical signs of Schmallenberg disease in a lamb.In addition to the rise in cases, two new counties have reported cases of the disease:

  • Greater London, and
  • Warwickshire.

SBV infection has still only been identified in areas at risk of midge incursion from Northern Europe during summer / autumn 2011, according to the Animal Health and Veterinary Laboratories Agency (AHVLA).

The agency claims it is most likely that domestic midges have transmitted SBV within the affected areas.

Veterinary staff requiring further guidance should contact their local AHVLA Laboratory (England and Wales) or SAC Disease Surveillance Centre (Scotland).
