Coronavirus cases have seen a fall in most areas where Banham Poultry’s workforce live according to new figures.

The figures, for the seven days to September 4, are based on tests carried out in laboratories (pillar one of the Government’s testing programme) and in the wider community (pillar two).

The rate is expressed as the number of new cases per 100,000 people.

The number of cases fell in Great Yarmouth and Breckland to 18 in each area after reported 31 and 40 cases in the seven days to August 31.

The number of cases in Great Yarmouth sees its infection rate stand at 18.1 cases per 100,000 people - the highest in Norfolk, but a significant fall from the previous week of 31.2 cases per 100,000.

The total showed 68 new cases reported across Norfolk in the last seven days to September 4.

In Norwich, the rate increased from 13.5 to 14.9 due to two new cases since the previous seven day total.

It comes as the deputy chief medical officer Professor Jonathan Van-Tam has expressed concern about the rising number of coronavirus cases in the UK.

Health leaders have warned there has been a rise in cases in young people aged 17 to 21.

“People have relaxed too much,” he said. “Now is the time for us to re-engage and realise that this is a continuing threat to us.

“That’s my concern, that if we don’t get on top of this, if people don’t start to take this seriously again, then there is a risk that that’s where we end up.”

Leader Andrew Proctor said the increased number of infections in Norwich, Breckland and Great Yarmouth were all linked to workers and their households.

Mr Proctor said: “My message to everyone in Norfolk today is clear - now is a time for togetherness.

“Everyone in Norfolk has a role to play. By following the guidelines, together we can protect ourselves, protect others and protect Norfolk.

South Norfolk also saw a small increase in its rate after reporting 12 new cases.

The rates were much lower in other parts of the county. Broadland’s rose slightly to 3.8, up from 3.1, with five new cases up from four in the previous seven days.

West Norfolk’s rate fell from 4.6 cases to 2.6, while two new case in North Norfolk meant the rate there went up from zero to 1.9 cases per 100,000.

However, for comparison, the rates in Norfolk are still way lower than some other parts of the country.

In England, Bolton has reported the most new cases in seven days with 350 new cases - the equivalent of 121.7 per 100,000 people. This is the highest rate in England and it is up sharply from 48.3 in the seven days to August 28.
