Bird flu has now been discovered in three more European countries according to a BBC news story.
The virus has been found in wild swans in Sicily, and other cases are suspected elsewhere in Italy, the country's health minister says.
A specialist UK laboratory has identified the virus in dead swans found in northern Greece and Bulgaria.
The H5N1 strain of bird flu has killed at least 80 people since early 2003, mostly in South-East Asia.
H5N1 was also recently found in Nigeria and it is expected to spread rapidly in Africa. It doesn't seem to be having much trouble spreading in Europe either. There have been no cases of human-to-human transmission so far which is good news.
