Rosselkhoznador: HPAI H5 Confirmed In Nizhny Novgorod Oblast















#12,497


While HPAI bird flu reports continue to dwindle in Asia (particularly South Korea and Vietnam), and across all of Europe, the same can hardly be said for western Russia, where today the 11th administrative district this month - Nizhny Novgorod Oblast - has reported outbreaks of HPAI H5.
All of this activity comes amid a growing bird flu contaminated food scandal (see Rosselkhoznador Investigation Into HPAI Contaminated Meat Distribution & Sale), and growing concerns that H7N9 and/or H5N6 could be poised to enter the country from the south, where they circulate widely in China.
Possibly contributing to this May surge is the fact that temperatures in west central Russia have been running 10 to 15 degrees below normal over the past month (see Accuweather Link).  Highs have routinely been in the 50s, and lows in the 30s, despite the approach of summer.

Two (translated) reports from the Nizhny Novgorod Oblast's Federal Service for Veterinary and Phytosanitary Surveillance (Rosselkhoznador). 

About Avian Influenza registration on the territory of the Nizhny Novgorod Region

Office of Rosselkhoznadzor for the Nizhny Novgorod region and the Republic of Mary El announces bird flu registration on the territory of the Nizhny Novgorod region.

As a result of laboratory tests conducted FGBU "ARRIAH" May 27, 2017 in the pathological material taken from dead birds contained in private farms in s.Pikshen Bolsheboldinsky District Nizhny Novgorod Region, highlighted the genome of influenza A virus subtype avian H5.

Currently in disadvantaged locations State Veterinary Service of the region, under the supervision of the Office of Rosselkhoznadzor for the Nizhny Novgorod region and the Republic of Mari El, spends flu outbreak eradication activities of birds and to prevent the further spread of infection.

On the establishment of quarantine for avian influenza in Bolsheboldinsky District Nizhny Novgorod Region

The decision to impose restrictive measures in order to eliminate epizootic flu outbreak Bird was adopted by the Commission on the organization of the protection of the Nizhny Novgorod region of the animal infectious diseases introduction of foreign states and border areas, in the next meeting which was attended by employees of the department of veterinary supervision of the Office of Rosselkhoznadzor for the Nizhny Novgorod region and the Republic of Mari El.

The reason for the Commission's work were the positive results of the laboratory studies conducted GBU BUT "Regional Veterinary Laboratory" patmateriala obtained from dead poultry and tests confirmed FGBU "Federal Center for Animal Health" (FGBU "ARRIAH").

During the committee agreed to continue approved by the Decree of the Governor of the Nizhny Novgorod region on 29.5.2017 number 45 Action Plan for the Elimination of the avian influenza outbreak in the village Pikshen Bolsheboldinskogo municipal district of Nizhny Novgorod region, according to which the border epizootic outbreak identified within the personal subsidiary farms in the village Pikshen Bolsheboldinskogo municipal district of Nizhny Novgorod region, whose territory declared disadvantaged paragraph borders threatened zones are set in the pre- ah Permeevskogo administrative boundaries of the village council, village council Pikshenskogo, Bolsheboldinskogo village council Bolsheboldinskogo municipal district of the Nizhny Novgorod region. surveillance zone boundary established within the administrative boundaries Bolsheboldinskogo municipal district of the Nizhny Novgorod region.

Quarantine is set to May 29, 2017 until further notice.

On the quarantine period in the territory of a troubled item prohibited paddock or other use of the birds outside the epizootic outbreak, visiting other homes, where there is poultry export of live poultry and derived from it the product, removal (removal) of inventory, equipment, manure, trade bird. The endangered area is prohibited export of poultry for slaughter to slaughterhouses located outside the threatened area, removal of all types of animals susceptible to avian influenza, and received from their products.

bird flu fact is the first case registered in the territory of the Nizhny Novgorod region.

The good news is that all of the Russian reports which have identified the HPAI H5 this spring have come back as H5N8 - a virus subtype which has never been found to infect humans. 
The big concern is that during its travels in Russia, Mongolia and China last summer, HPAI H5N8 picked up a number of changes (via reassortment with other viruses) that made it far more pathogenic in birds (see EID Journal: Reassorted HPAI H5N8 Clade 2.3.4.4. - Germany 2016).

The more H5N8 spreads this summer, the more opportunities it could have to evolve further. So even though Russia's HPAI H5 outbreaks may seem small, scattered, and of little import today, they may well be setting the table for what gets served up to Europe next fall.
