Dorset avian influenza epidemiology report published

4 February, 2008

Defra has today published an epidemiology report into the H5N1 avian influenza case in wild birds in Dorset.
The report was prepared by the National Emergency Epidemiology Group.
Analysis of the virus indicates that it is related to contemporary viruses from continental Europe and is most closely related to a cluster of isolates recovered in mid to late 2007 from wild and domestic birds in the Czech Republic, Romania and Poland.

The source of infection for the swans has not been identified, however the most plausible hypothesis is that it was introduced by one of the migratory wild birds that make up part of the population on the Fleet during the winter.
