Dead swan had deadly H5N1 strain of bird flu

British scientists have confirmed that a dead swan found in the Czech Republic on Saturday did have the deadly H5N1 strain of bird flu. It is the country's first case of the virus. On Wednesday a second dead swan infected with bird flu was found three or four kilometres from where the first was discovered in Hluboka, south Bohemia. Special veterinary measures have been introduced in 3- and 10-km zones around Hluboka in line with EU rules.
