As health authorities confirm two poultry workers have tested positive for bird flu in England, this is all you need to know about the latest developments with regard to a disease that has seen hundreds of birds in the North East die over recent months.
At this stage it is not known where in England the two poultry workers are based, though the UK Health Security Agency believes the are no signs of person-to-person transmission. The two cases are thought to be linked to exposure to sick birds on a single poultry farm where the two people were known to have recently worked.
Contact tracing is taking place as a precaution.
