H5N1 Outbreak in Denmark


According to a posting on ProMED on March 4th, an organic egg-production flock comprising 7,000 hens near Terndrup was diagnosed with H5 avian influenza of low pathogenicity. The diagnosis was confirmed by PCR assay carried out by the Danish National Veterinary Institute.

The flock was depleted and a 1 km quarantine zone imposed. The origin of the infection is unknown but was most likely associated with migratory birds as the flock was not confined.

The previous diagnosis of H5 influenza in Denmark involved a flock of game birds in June 2018.
