    • In June 2016, we collected samples from 13 dead and 30 hunter-harvested wild aquatic birds around Uvs-Nuur Lake (Tyva Republic) at the Russia–Mongolia border. We isolated a total of 11 subtype H5 influenza viruses from birds of various species: the black-headed gull (Larus ridibundus), gray heron (Ardea cinerea), common tern (Sterna hirundo), great crested grebe (Podiceps cristatus), and great cormorant (Phalacrocorax carbo). Phylogenetic analysis showed that the HA, NA, and NS genes of three isolates clustered with H5N8 clade group B HPAIV viruses identified in eastern China in 2014. The PB1, PB2, PA, NP, and M genes clustered with LPAIV identified in Mongolia, China, and Vietnam.

Epidemiological and Molecular Analysis of an Outbreak of Highly Pathogenic Avian Influenza H5N8 clade in a German Zoo: Effective Disease Control with Minimal Culling. Transbound Emerg Dis. (2016 Nov 15) [Reference].
    • Highly pathogenic avian influenza A virus (HPAIV) subtype H5N8, clade, caused five outbreaks in poultry holdings in Germany between autumn 2014 and February 2015. In addition, birds kept in a zoo in north-eastern Germany were affected. Only a few individual white storks (Ciconia ciconia) showed clinical symptoms and eventually died in the course of the infection, although subsequent in-depth diagnostic investigations showed that other birds kept in the same compound of the white storks were acutely positive for or had undergone asymptomatic infection with HPAIV H5N8. An exception from culling all of the 500 remaining zoo birds was granted by the competent authority. Restriction measures included grouping the zoo birds into eight epidemiological units in which 60 birds of each unit tested repeatedly negative for H5N8. This case demonstrates that alternatives to culling exist to rescue valuable avifaunistic collections after incursions of HPAIV.


Recommendations for affected countries and those at risk

    • FAO recommends intensified surveillance and awareness raising by national authorities.
    • There is no benefit to be gained in attempting to control the virus in wild birds through culling or habitat destruction. Spraying of birds or the environment with disinfectant – for example sodium hypochlorite or bleach – is considered potentially counter-productive, harmful to the environment and not effective from a disease control perspective.
    • There is also no justification for any pre-emptive culling of endangered species in zoological collections. Control measures for captive wild birds in places where virus is detected should be based on strict movement control, isolation and only when necessary limited culling of affected birds.
  • General recommendations
    • It is important to report sick or dead birds – both wild birds and poultry - to local authorities (veterinary services, public health officials, community leaders etc.). These should be tested for avian influenza viruses.
    • Wash hands properly and often. You should always do so after handling birds or other animals, when cooking or preparing animal products, and before eating.
    • Eat only well-cooked meat products, and refrain from collecting, consuming or selling animals found sick or dead.
    • Seek immediate advice from your physician if you show signs of fever after being in contact with poultry, farmed birds, wild birds or other animals.
  • Recommendations to poultry producers
    • Farmers and poultry producers should step up their biosecurity measures in order to prevent potential virus introduction from wild birds or their faeces.
    • It is important to keep poultry and other animals away from wild birds and their sub-products or droppings through screens, fencing or nets.
    • Commercial poultry operations and backyard poultry owners should avoid the introduction of pathogens through contaminated clothes, footwear, vehicles or equipment used in waterfowl hunting.
  • Recommendations to hunters
    • Hunting associations and wildlife authorities should be aware that H5N8 and other avian influenza viruses might be present in waterfowl hunted during fall migration 2016 and that hunting, handling and dressing of shot waterfowl carries the risk of spreading avian influenza viruses to susceptible poultry.
    • Avoid introduction of avian influenza viruses to poultry through fomites (clothing, boots, vehicles, etc.) and do not feed wild bird scraps to poultry.
    • Water bird scraps should not be fed to domestic animals (cats, dogs, or poultry).
    • Any waste from hunted birds should be treated as potentially contaminated and safely disposed of.
  • Recommendations to national authorities
    • Increase surveillance efforts for the early detection of H5N8 and other influenza viruses in poultry and dead wild birds.
    • Provide means for reporting sick or dead birds, e.g. hotlines and collection points.
    • Raise awareness of the general population, poultry producers or marketers and hunters both about the disease as well as the reporting mechanisms for sick or dead birds.
    • Collaborate with hunting associations for laboratory testing of hunted birds, especially in areas that are known to be affected.
    • Provide means for and ensure proper disposal of carcases after sample collection.
    • Ensure that the means for laboratory testing are in place to detect the currently circulating avian influenza viruses, especially those of clade
    • Gene sequencing should be performed for all H5 viruses detected, and results shared with the global community in a timely manner. This will aid understanding of how the virus is spreading.
    • Action on wild birds not recommended.


{x} Reports of H5N8 HPAI events in Taiwan, Province of China, are not included in this update since the virus belongs to a genetically different strain.
