A Hungarian government spokesman says the deadly strain of bird flu virus has been found in the southern part of Hungary.

The spokesman, Andras Batiz, said Tuesday three wild swans found last week have tested positive for the H5N1 virus.

German veterinary officials Tuesday confirmed 22 new cases of flu in birds on the island of Ruegen bringing the total in the country to 103.

The German government announced Monday the virus had spread to the mainland. One hundred three cases have now been found in wild birds in Germany.

Croatia has confirmed the H5N1 virus in a wild swan found dead last week.

France and the Netherlands are petitioning EU animal health experts so they can vaccinate their poultry.

Some EU countries are skeptical if such inoculations can ward off the deadly virus.

Bird flu has killed more than 90 people since 2003 in Asia.
