During that time Cornwall and Isles of Scilly as a whole recorded a combined 1,668 positive test results, which was 164 more than during the preceding week.

It marked a rise of 10.9% - the first weekly case rise Cornwall has seen for a few weeks during the Packets twice-weekly cluster map updates.

The case rate is now averaging 289.8 cases per 100,000 people, which is a rise on the 261.2 cases per 100,000 last Saturday.

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.

Clusters are only shown when there are three or more new cases reported at any one time.

Anywhere with between zero and two cases shows white in order to "protect the privacy of individuals and prevent disclosure", the accompanying information states.
