Table supplied by AHVLA. Figures correct as of February 24, 2012.Since our last update (Feb 22) positive cases of SBV virus have now been identified in Berkshire, Somerset and on the Isle of Wight.

However, according to the Animal Health and Veterinary Laboratories Agency (AHVLA) So far, none of the affected farms have reported importing animals during 2011 from the affected areas in mainland Europe.

The most recent update from AHVLA also notes the discovery of positive results in Gloucestershire, although this is not borne out by the official figures published by the agency (right).

Schmallenberg Virus is not a notifiable disease, but farmers and vets should remain vigilant and report any suspicious cases to AHVLA for testing as part of our enhanced surveillance, says DEFRA.

Suspect cases will be sampled for histopathological and virological examinations. Confirmation of infection is by detection of virus sequences using real-time PCR on tissues. There is currently no blood test available.

The European Centre for Disease Prevention and Control suggests that there is a low likelihood of any risk to public health.
