Although still greatly outnumbered by reports of HPAI H5N8, we continue to see an expansion of reassorted HPAI H5N5 detections across Europe, with this new virus previously reported in The Netherlands, Italy, Montenegro, Germany, Greece, Slovenia, Poland, and Macedonia.
Today it is the Czech Republic's turn, as their Státní Veterinární Správa (State Veterninary Administration) reports their latest findings on their website.

13. 2. 2017 yesterday evening confirmed 28 outbreak of bird flu in backyard poultry in Volyn district. Strakonice. The farm has about 100 pieces of water and gallinaceous poultry to be killed during the day.
Laboratory results of examinations of dead swans from the Liberec Zoo, confirmed the H5N5 subtype of bird flu, which was recently captured in Germany.
In connection with bird flu have been in the country since the beginning of the year so far killed more than 58,000 birds. Bird flu has also yet to be proven in 50 wild birds in 12 regions (especially swans, but also ducks, geese and herons).
10. 2. 2017 Confirmed new outbreak of avian influenza H5 in a backyard in the town of Zdar nad Orlicí Rychnov the Princess in the Hradec Kralove region. Breeder reported the deaths of three geese. In raising a total of about 60 pieces poultry (chickens, ducks, geese). During the morning was culling the infected breeding. It was subsequently issued regulations for restricted zones.

Described as `highly aggressive' by German Agriculture Minister Robert Habeck, H5N5 was first reported in Europe 2 months ago. Germany's Friedrich-Loeffler-Institut (FLI) describes this new virus as:
Since mid-December 2016 a further subtype, H5N5, has been circulating in wild birds, which now has first been introduced into a poultry holding. This virus is is likely to be a reassortant based on the original H5N8. Mixed viruses, so-called reassortants, of avian influenza viruses are generated, if several virus subtypes are present in one infected animal and exchange genetic material during replication. Generation of reassortants must be expected when different high and low pathogenic influenza viruses are circulating in one population.
