The report concludes that, at the time of writing, the outbreak is confined to the index case which is also the first case and a secondary case as a result of transmission by vehicles, people or other things on the sites.

It has not been possible, at this stage, to categorically identify the source of the outbreak. This initial report states that no evidence has so far been found to indicate introduction via infected poultry or poultry products or vehicles/people transporting them, from countries which have undisclosed infection in their domestic turkey, geese and duck population.

Wild birds cannot be ruled out as a source of infection. The report states that, to date, there is no evidence of H5N1 infection in the local wild bird population or in GB as a whole, but the continued surveillance may help clarify the infection status of the wild bird population.

Further surveillance, testing and epidemiological work on this outbreak is ongoing.
