Through United Kingdom, Pathogen and Import

The cause of the outbreak was not determined. However, it was considered significant that Bernard Matthews regularly transports turkeys and turkey products between the UK and its plant in Hungary, and that the H5N1 strains previously found in Hungary, and those found at Suffolk, were effectively genetically identical.

Background

H5N1

H5N1 is a subtype of the Influenza A virus, the viruses responsible for influenza in humans and many other animal species. A bird-adapted strain of H5N1, called HPAI A(H5N1) for "highly pathogenic avian influenza virus of type A of subtype H5N1", is the causative agent of H5N1 flu.

HPAI A(H5N1) is considered an avian disease, although there is some evidence of limited human-to-human transmission of the virus. A risk factor for contracting the virus is handling of infected poultry, but transmission of the virus from infected birds to humans is inefficient. Poultry farming practices have changed due to H5N1. The cost of poultry farming has increased, while the cost to consumers has gone down, due to fears from H5N1 driving demand below supply.

Recent outbreaks in the UK and rest of EU

The outbreak was the third instance of H5N1 detected in the United Kingdom. The first outbreak occurred in October 2005 among exotic birds imported from Taiwan and South America at a privately owned quarantine facility in Essex, England. The second instance involved a dead whooper swan found to have the virus in Cellardyke, Scotland in April 2006. A corresponding incidence on a farm in south-eastern Hungary was confirmed by the European Commission on 25 January 2007.
