Somewhat surprisingly - even during Europe's 2016-2017 record setting avian epizootic - Norway has never reported HPAI in migratory birds or poultry before. Neighboring Scandinavian countries, like Sweden, Denmark, and Finland - while not as hard hit as many central European nations - have reported multiple outbreaks over the past 15 years.
Norway's lucky streak has ended with the announcement yesterday by the The Norwegian Food Safety Authority, of the first detection of HPAI in a migratory bird (wild goose) in Rogaland, located on the Southwestern coast.
It is too soon to know if this detection is a one-off event due to a lone wayward migratory bird, or if it heralds a bigger threat to the region. But due to the risks poultry interests in the region are ordered to boost their biosecurity.
This report from Norway's FSA.
Bird flu in Norway and Europe in autumn 2020Published 19.11.2020 Last changed 27.11.2020
Highly pathogenic bird flu has been detected in Norway, Sweden, Denmark and several countries in Europe this autumn. The bird flu that is now being detected is first and foremost a risk to birds and not humans. The risk of infection to humans is considered by the Norwegian Institute of Public Health to be very low.
The Norwegian Food Safety Authority introduces a curfew to prevent infection of domestic birds
Bird flu has been found on a wild goose in Rogaland. To prevent infection from wild to domestic birds, the Norwegian Food Safety Authority is now introducing a curfew for poultry in all coastal municipalities from and including Rogaland and the entire coastal strip up to Oslo and even former Østfold.
A curfew means that all domestic birds must be indoors or possibly under a roof.
The infection situation is assessed on an ongoing basis
The infection situation can change quickly and the Norwegian Food Safety Authority therefore makes continuous assessments of the situation.
The infection is thought to come from migratory birds, and based on previous years' experience, it is unlikely that Norway will be affected by the main migration of birds in the autumn, along the south-western migratory route from eastern nesting areas.
The Norwegian Food Safety Authority is not aware that there is knowledge of changed migration routes that will change the risk of introducing HPAI to Norway in the autumn of 2020. While both Sweden, Finland and Denmark have detected HPAI in poultry and wild birds before, HPAI has never been detected in Norway.
Major consequences for poultry - preventive measures can be implemented at short notice
The consequences of any infection from wild birds to poultry can be very serious for the poultry herd.
If the Norwegian Food Safety Authority considers that the risk of infection to Norway increases, we will consider initiating preventive measures to prevent infection from wild to domestic birds. Such preventive measures can be implemented at short notice.
This year's variant of bird flu is dominated by the H5N8 virus. The virus is highly pathogenic, which means that it is highly pathogenic to poultry.
Low risk of infection for humans
There are no previously known cases of infection from birds to humans with this virus, and the risk of infection to humans is considered very low.
Remember to avoid direct physical contact with sick and / or dead birds, as these e.g. may be infected with Salmonella .
Europe has seen three previous major introductions of HPAI H5, with the first occurring in 2005-2006 (with H5N1), again in 2014-15 (with H5N8's first appearance), and lastly with the 2016-2017 HPAI H5N8 epizootic (see map below).
While scattered outbreaks (particularly in Eastern Europe) of HPAI have occurred outside of the 3 above mentioned epizootics, these three events (along with this year's uptick) have all been associated with a reassortment event that altered the virus's virulence or behavior.
Not all reassortments are bad, however. The reassorted HPAI H5N6 virus that briefly appeared in Europe during the winter of 2017-2018 was considerably less robust and widespread than the HPAI H5N8 virus it supplanted.
Meanwhile, in South Korea, where they have announced numerous environmental detections of HPAI H5N8 from migratory birds this fall, they are reporting their first outbreak in a poultry (duck meat) farm in Jeongeup, North Jeolla.
This (translated) statement from MAFRA, South Korea's Ministry of Agriculture, which has imposed a 48-hour nationwide stop movement order for poultry farms, Livestock (feed factories, slaughterhouses, etc. ) and livestock vehicles.

Highly pathogenic avian influenza virus test positive in water collected in Kagoshima prefecture (6th case in wild birds)
November 27, 2nd year of Reiwa
Highly pathogenic avian influenza virus (H5N8 subtype) was detected (positive) in an environmental sample (water) collected in Izumi City, Kagoshima Prefecture on Monday, November 23, 2nd year of Reiwa by a test conducted by Kagoshima University. There was a report that it was done. The collection point will be the same as the collection point where the highly pathogenic avian influenza virus was detected on November 13th and 20th.
