Vets destroy bird flu flock

State veterinarians have destroyed all birds on a poultry farm near the east Bohemian village of Tisova after they were discovered to have been infected with the deadly H5N1 strain of the bird flu virus. The farm is now being disinfected. The vets are expected to cull all birds in the surrounding district over the weekend in an effort to contain the outbreak of the disease, which is the first case of bird flu in the Czech Republic.
