The coronavirus outbreak at Banham Poultry has seen cases rise in both Breckland and Great Yarmouth - but not other areas of Norfolk so far.

After being at a very low level for several weeks, Public Health England figures of those testing positive show a sudden increase in the two areas.

In Breckland, where Banham Poultry is based, 12 people tested positive on Monday. There is delay of a few days in the figures so that will rise in the coming week. The last time there was such a high number of confirmed coronavirus on a single day in Breckland was May 15.

A total of 75 people have tested positive at the meat factory near Attleborough with 347 tests done.Many of the workers also live in Great Yarmouth, Dr Louise Smith, head of public health in Norfolk said, and that is also reflected in the latest figures.

There, nine people are currently showing as testing positive on Monday - the highest number in a single day in Great Yarmouth since May 19.
