There are now 15 clusters of confirmed coronavirus cases in Cornwall - up from nine in three days, with the number of positive test results more than doubling in that time.

On Friday the Packet reported that the government map of coronavirus cases in England showed there were 55 cases spread over nine cluster areas in Cornwall, but this lunchtime it is now showing a total of 134 cases in 15 areas.

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 each area is 5,000 and the average is 7,200.
