As of their cut-off date (Dec 12th), 406 outbreaks and cases have been reported, an increase of 138 since December 5th. A roughly 35% acceleration in the number of new cases over the previous week (n=102).

Since the latter situation the 5 December , new highly pathogenic avian influenza (HPAI) subtype H5N8 were reported in Europe, mainly in Germany (98 cases in birds compared to 63 last week) and Hungary (120 breeding centers compared to 43 last week). The total number of outbreaks and cases reported continues to increase and is now 406 (compared to 268 last week to 5 December) in which 245 wild birds (35 species affected), 155 farms and 6 within the captive birds (Tables 1 & 2). Since the last update (December 5), Serbia is now affected by the HPAI H5N8 virus and declared its first outbreak on December 6 following the identification of the virus in wild birds 6 on 2 December.
The HP H5N8 virus is also present beyond Europe. An outbreak of HPAI H5N8 has been Reported on 13 November 2016 in breeding poultry breeding in Israel. The cases were also reported for the first time in Egypt on 30 November at two coots (Fulica atra), Ukraine on November 30 in a livestock (species unspecified) and Tunisia on December 1 of 17 coots (Fulica atra) and 13 Wigeon (Anas penelope). Iran has identified five outbreaks of laying hens between 14 and 28 November 2016.
The virus circulates also in Russia, with a reported case in the avifauna in June 2016, two outbreaks Declared on November 23 in domestic farms (geese, chickens and guinea fowl) and one Outbreak reported on December 8th in a breeding of laying hens.
(SNIP Charts & Graphs)
The mortality reported in breeding is variable depending on the species. For breeding mono-specific, this mortality varies from 0.3 to 33% but on four farms only for Gallus gallus, around 20% in turkey farms (but only two farms), from 0 to 70% in palmipeds (out of 21 farms, this mortality is between 10 and 70% for 6 of these 21 farms).
Despite the caution in the interpretation (time of intervention in relation to Infection, epidemiologically linked breeding which could be at the very beginning of infection, Etc.), it should be noted that this strain appears to have an unusual virulence in breeding palmipeds.
