Czech Republic Reports H5N5 In Dead Swans At Liberec Zoo


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.

Vysocepatogenní avian influenza in the Czech Republic; current information as of February 13, 2017

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. This is the first outbreak of bird flu on the territory of the.
In the afternoon confirmed a new case of avian influenza H5 in dead swans belonging ZOO Liberec. The swan was placed along with four other swans and geese in four closed isolation area outside the zoo. In the early evening hours were the remaining birds in the outbreak in accordance with applicable legislation euthanized. The State Veterinary Administration in cooperation with the staff of the zoo tightens oversight of the health status of other birds at the zoo. This is the 27th outbreak of bird flu in the Czech Republic and the third focus of the Liberec Region.

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.
