Avian influenza in poultry

In November 2021, outbreaks of highly pathogenic avian influenza (HPAI) occurred for the first time in poultry in Norway. HPAI virus of the subtype H5N1 was detected in two commercial layer flocks in Klepp municipality in Rogaland County. Prior to this, virus of the same subtype was found in wild birds in the same geographical area.

Avian influenza (AI) is monitored in poultry and in wild birds.

The main goal of the surveillance programme for AI in poultry is to document that Norwegian poultry flocks are free of influenza A infections of the subtypes H5 and H7.

The surveillance programme for AI in wild birds serves as a potential early detection and monitoring system in relation to influenza A viruses of avian origin, with special emphasis on HPAI H5 and H7 subtype viruses in the wild bird reservoir.
