Schmallenberg Virus Spreads In UK

20 February 2012

UK - Schmallenberg virus (SBV) has now been identified in samples submitted from 52 farms across the counties of Norfolk, Suffolk, Essex, Kent, East Sussex, West Sussex, Hertfordshire, Surrey, Hampshire and Cornwall.

Due to the increase in reports of SBV identified in France, the areas at comparatively higher risk in the UK have been revised in line with the plume modeling data from the summer which models areas at risk of midge incursion from northern Europe. These areas include Dorset, Devon, Cornwall, Somerset, Gloucestershire and Wiltshire and therefore an increase in risk for South Wales.

The timing of the most dense plumes would have been in late October for this south west region. This is therefore in line with the appearance of deformities in lambs being born now, assuming the highest risk period for lambs is if the mother is infected at approximately one month into gestation.

The majority of the GB cases of SBV infection have been diagnosed in sheep to date. Only three cattle in the UK, in Norfolk, Suffolk and West Sussex have been identified with the virus.
