Migrant bird suspect for bird flu
Defra has today published an epidemiology report into the H5N1 avian influenza case in wild birds in Dorset
While it has not been possible to conclusively identify the source of the infection, the most likely hypothesis is that it was introduced by an infected migratory wild bird.
It has also been established that the strain of the virus is similar to those isolated in continental Europe in the latter part of 2007.
The report outlines the detailed surveillance that has been carried out in the area, both in domestic and wild bird populations. There is currently no evidence to suggest widespread disease in the wild bird population, but poultry keepers in the area are reminded to remain vigilant and report any signs of disease immediately. There remains no evidence of disease in domestic birds.
At the time of writing disease was confined to the six birds on the same premises. This represents a very low level of infection in the wild bird population on the site.
