National Veterinary Research Institut Poland has release sequences for all 8 gene segments from 2017 H5N5 isolate from a mute swan.

National Veterinary Research Institut Poland has released H5N8 sequences for all eight gene segments from a Herring Gull from a Nov 9 collection in Swinoujscie Poland. This sequence matches earlier sequences from Poland, Germany, and Sweden.

National Veterinary Research Institut Poland has released 7 sets (H5 and N8 or H5 only) of sequences. None of these sequences match the dominant sub-clade reported for Poland, Sweden, France, England, Germany, and Denmark. Three of the sequence match the Croatia / France sub-clade, while the other four are novel. Although 3 countries have reported H5N5, no sequences have been released. The two sets of novel sequences in Poland may be related to new constellations.
