A big threat looms as bird flu spreads to West Europe
Avian influenza is no longer a largely Asian virus. It has struck in the heart of Western Europe and there is no saying where it will spread from there. The discovery of the highly pathogenic H5N1 strain in wild swans in Greece and Italy earlier this week marks the virus’ arrival in the western world. The H5N1 strain has already killed over 90 people in Asia over the last three years, and subsequently spread to Russia, Kazakhstan and Mongolia last year. The last few months have seen the deadly virus afflict flocks of wild migratory birds in Romania, Turkey, Bulgaria, and even as far as Nigeria.
