Coronavirus cases in Cornwall and Isles of Scilly have risen by almost a third in the past week.

The latest figures on the Government's cluster map show 493 reported cases in seven days.

That is 117 more than on the same map a week ago, a rise of 31 per cent.

Of these, 79 have been recorded in the four days since Saturday.

The update, as of 4.22pm today (Wednesday, November 18) represents new cases by specimen date in the seven days leading up to Friday last week, November 13.

The most recent five days are left off due to incomplete data not reflecting the true number of cases.

There has also been a rise in the number of 'clusters', with 56 now showing - a rise of five week-on-week and seven more than on Saturday, when the areas had dropped to 49.

Many of the new areas are in the far north and east of the Duchy, with two particular spikes emerging in Bude, where there are 39 cases showing, and Kingsand, Antony & Maryfield, just across the water from Plymouth, which has 65 cases and an individual rolling rate of 1,027.7 cases per 100,000 - well above the national average.

The rolling rate for Cornwall and the Isles of Scilly as a whole, however, is 86.2 cases per 100,000 people - which is below the national average.

While cases have shot up close the Devon border, it is better news further west, where some cluster areas, such as the Lizard Peninsula, Penzance and St Just, have dropped off the map since the weekend update on Saturday.

Clusters are only shown when there are at least three confirmed results, with anywhere having between zero and two cases showing white in order to "protect the privacy of individuals and prevent disclosure."

Other areas, such as Falmouth and Helston, are showing no change in the number of cases from four days ago.

The map shows positive cases by 'Middle Super Output Area' - the name the government gives to the break-up of larger towns and groups of neighbouring towns and villages, with groupings covering a greater area than others.

The minimum population in each area is 5,000 and the average is 7,200.
