The H5N8 virus was detected in sick and injured birds in February and early March this year, including in a swan found dead in Helsinki's Eläintarhanlahti park and a goshawk sent to Korkeasaari Wildlife Hospital from Kumpula. Several birds infected with avian influenza have been found in Uusimaa this winter.

Authorities fear the spread of a very deadly bird flu virus after finding dead birds. Domestic birds should from now be kept indoors, and people are asked not to feed birds in the wild.

Bird flu, or avian influenza, has struck the Swedish poultry industry hard this winter. Since November, thousands of turkeys and more than one million chickens have been culled. Malin Grant, an epidemiologist at the National Veterinary Institute, says the virus can be deadly for domestic poultry but the strains currently circulating don't easily infect or spread between people.

The particularly dangerous strain of avian influenza virus H5N8 has been detected in a mute swan found on the Kopli peninsula in Tallinn.

Bird flu has been detected in a goose found in Rogaland. The Veterinary Institute has analyzed samples from the bird, which show highly pathogenic bird flu A (H5N8). This virus has caused outbreaks among birds in several European countries this autumn.
