Affected population On 23 February 2015, a suspicion of avian influenza was reported to the National Food Chain Safety Office. The local authority immediately visited the affected holding, which is located in Füzesgyarmat, in Békés County. 22,000 fattening ducks are kept in the holding. Neurological signs, nasal discharge and increased mortality were observed. Official samples were taken on the same day. On 24 February, the National Reference Laboratory confirmed avian influenza H5N8 strain. In the neighborhood of the affected holding, there are three contact holdings. Altogether 161 411 birds were kept in the affected and in the contact holdings, all of them were killed and destroyed.

Source of the outbreak(s) or origin of infection
  • Unknown or inconclusive
Epidemiological comments On 24 February, the National Reference Laboratory confirmed avian influenza virus H5N8 by RT-PCR and, on the next day, by sequencing partial HA and NA sequence fragments. The amino acid sequence at the hemagglutinin cleavage site is consistent with highly pathogenic avian influenza (HPAI). Preliminary results suggest that the sequences are very closely related to the Asian and also to the four European H5N8 HPAI virus sequences reported so far. Whole genome sequencing is in progress.
