Implementation of disease control measures according to the Directive 2005/94/EC have
been put in place, and epidemiological investigations are ongoing.
Since the last report on 17 November, Denmark has reported one outbreak of HPAI H5N8
in poultry on a commercial poultry farm, containing approximately 25,000 birds. There
have also been 20 reports of HPAI H5N8 in wild birds, and two reports of HPAI H5 in wild
birds.
While most reports continue to be from Jutland, there were a small number from
Sjaelland (Zealand). Eleven of these reports related to dead barnacle geese. Other

herring gull.
France has reported one outbreak of HPAI H5N8 (as reported to the OIE) in poultry. This
was in the pet department of a garden centre. This was in the French department of
Haute-Corse, in the northern part of the island of Corsica (in total, there were 575
specimens of various species (poultry and ornamental birds).
The birds were culled on 15 November, and the garden centre's pet facility is now closed. Epidemiological investigations are ongoing.
Since the last report on 17 November, in Germany there have been 70 further reports of
HPAI H5N8 in wild birds.
While the majority of outbreaks continue to be in the north, and primarily in South Jutland, isolated cases have been identified further south, through Prignitz (in north-west Brandenburg – in a bean goose), Berlin (the federal state, southwest of the city – a greylag goose), and as far south as Nordsachsen (North Saxony – a mallard duck). There have also been three reports of HPAI H5N5 in wild birds.

The same virus was detected: HPAI H5 viruses belonging to the 2.3.4.4 B clade. The HA sequence surrounding the cleavage site is highly related to that of HPAI currently circulating in Northern Europe. Identification of the NA subtype and characterization of the full genome is in process.
