Zoikes! H5N1 was confirmed on a free-range poultry farm in Suffolk, Englad on November 12, 2007. The farm grows 5000 turkeys in 5 groups of 1000, 1118 ducks, and 410 geese. While H5N1 was not detected in the geese, 2% of ducks were infected, as well as a more than 50% infection prevalence in two of the geese groups. It is believed that the infection started in one of the turkey groups and that the birds were infected from a single source. However, results from epidemiological studies indicates that the virus was not introduced from imported poultry, although the current isolate is genetically closest to the virus islated from wild birds in the Czech Republic in mid-2007. H5N1 has not been detected in wild bird populations, but infection from migratory species from central Europe cannot be excluded.
