Avian Influenza in Animals

Greece (HPAI H5N8)

The World Organization for Animal Health (OIE) reports that highly pathogenic avian influenza (H5N8) was found in a wild swan found in the Evros river delta in Eastern Macedonia and Thrace.

Ireland (HPAI H5N8)

A new case of highly pathogenic avian influenza (H5N8) was discovered in a wild duck in the town of Wexford in Ireland. The bird was found alive but unable to fly. Control measures include mandatory housing of poultry. The public was advised to report multiple wild bird deaths in the same location. Further testing will determine whether the virus found in Ireland is the same strain that has been found in Great Britain and Europe.

Japan (HPAI H5N6)

The Kyoto Municipal Government reports that highly pathogenic avian influenza (H5N6) was found in seven wild swans. Eight mute swans at the Kyoto Racecourse in the Fushimi Ward died suddenly. Genetic testing confirmed that seven of the eight birds were infected with H5N6. The remaining 38 swans on the premises were culled.

The government has “sterilized” farms and ponds within 10 km of where the cats died. Twelve people who had contact with the two positive cats have been placed on antivirals. Two dogs raised together with the cats have tested negative. The government will test stray cats in heavily affected districts elsewhere in the country to determine the extent of their exposure to H5N6.
