| 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. |
