Defra (Department of Food, Environment and Rural Affairs) has released a preliminary epidemiological report on the H7N7 outbreak in Oxfordshire, that states as of June 11th the outbreak was confined to one farm.
Various theories are being examined to try to determine how the highly pathogenic virus appeared at this farm. One thought is it may have `evolved' from a low path H7N7 virus.
Investigations are ongoing.
A Hat tip to Shiloh on Flutrackers for leading me to this report.

Avian influenza epidemiology report published
Defra has today published an epidemiology report into the Avian Influenza outbreak confirmed in Oxfordshire on 4 June.
The report concludes that, at the time of writing (11 June), the outbreak is confined to a single premises, and there is no evidence of infection in the Protection Zone or of spread to any other premises. However, investigations continue.
The report suggests that it is possible that the Highly Pathogenic H7N7 Avian influenza derived from a Low Pathogenic strain already present on the farm, analysis and investigations are ongoing, and a number of source hypotheses are being considered.
Chief Veterinary Officer, Nigel Gibbens, said
“The UK is at a constant but low level of risk of the introduction of Avian Influenza, and the report highlights the need for flock owners and poultry vets to remain vigilant for signs of disease, including the possibility of low pathogenic Avian Influenza. I would encourage all keepers to maintain good quality records and practise high standards of biosecurity.”
The Protection and Surveillance Zones remain in place. Further surveillance, testing and epidemiological work on this outbreak are ongoing.
