Slovenia has reported a case of H5 bird flu in a swan, the European Commission said Sunday.

Samples have been sent to the UK for further tests to see if that is the highly pathogenic H5N1 strain, potentially dangerous to humans.

A day earlier, the virus was confirmed in Bulgaria and Greece, and also hit into West Europe.

The H5N1 was found in wild birds in Italy's Sicily, Calabria and Apulia.

But Italian authorities did not immediately take any precautions at the Winter Olympic Games in Turin, world media say.

"They will let us know if they want us to give specific information to the athletes," Giuseppe Gattino, spokesman for the Games organizing committee, has said referring to regional health authorities in Piedmont.
