Avian Influenza H5N8 – Global situation update as of 10 May 2017



Information provided herein is current as of the date of issue. Information added or changed since the last H5N8 situation update appears in red. Human cases are depicted in the geographic location of their report. For some cases, exposure may have occurred in one geographic location but reported in another. For cases with unknown onset date, reporting date was used instead. FAO compiles information drawn from multiple national (Ministries of Agriculture or Livestock, Ministries of Health, Provincial Government websites; Centers for Disease Prevention and Control [CDC]) and international sources (World Health Organization [WHO], World Organisation for Animal Health [OIE]) as well as peer-reviewed scientific articles. FAO makes every effort to ensure, but does not guarantee, accuracy, completeness or authenticity of the information.

    • In November 2016, HPAI H5N8 was detected in a commercial layer farm in Tehran province. The diagnosis was based on real-time reverse transcriptase PCR (RRT-PCR) and sequencing of haemaglutinin (HA) and neuraminidase (NA) genes from suspected samples. Genetic and phylogenetic analysis of the HA gene demonstrated that the Iranian HPAI H5N8 viruses belong to the HPAI H5 virus clade and cluster within group B (Gochang-like). In particular, the highest similarity was found with the sequences of the HPAI H5N8 identified in Russia in 2016.

Genetic and phylogenetic characterizations of a novel genotype of highly pathogenic avian influenza (HPAI) H5N8 viruses in 2016/2017 in South Korea. Infect Genet Evol. 2017 May 3. pii: S1567-1348(17)30152-1. doi: 10.1016/j.meegid.2017.05.001. [Epub ahead of print]. [Reference].
    • During winter 2016/17, novel H5N8 viruses were isolated from migratory birds in South Korea. The HA gene of these H5N8 viruses belonged to clade, similarly to recent H5Nx viruses, and originated from a minor lineage of H5N8 that emerged in 2014 and then disappeared. At least four reassortment events occurred with different subtypes (H5N8, H7N7, H3N8 and H10N7) and a chicken challenge study revealed these isolates were HPAI viruses according to OIE criteria.


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 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 (contact:
    • Gene sequencing should be performed for all H5 viruses detected, either in national or international reference laboratories. FAO can assist with the shipment of samples (contact: Results should be shared with the global community in a timely manner to 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.
