The European Union has announced new measures to combat the spread of bird flu. After emergency talks in Brussels, EU veterinary experts called on governments to pinpoint high risk areas and keep poultry separate from wild birds, which carry the virus.The move follows confirmation that the deadly H5N1 strain of bird flu has reached western Turkey. The virus has also been found in Romania although the variant is yet to be identified. Thousands of birds have been culled in the affected areas of the Danube delta region. Although no human cases of the disease have been reported in Europe, several nations have stockpiled anti-viral drugs amid growing unease. Scientists fear that if a person were to be infected with normal flu at the same time as bird flu, the avian virus could mutate to allow easy human-to-human transmission. Experts believe more than seven million people may be killed if the deadly virus mutates and spreads from person to person.
