A coronavirus app is highlighting the UK’s infection hotspots.

A heatmap shows how many people in the area are using the app - Covid Symptom Study - and how many active cases there are.

It shows that there is an estimated 1,884 new cases of coronavirus each day across the UK, with 10 to 57 new cases per million in the South West daily, and 28,272 people are currently predicted to have symptomatic Covid in the UK.

More than four million people have downloaded the app with the data being analysed in collaboration with King’s College London researchers.

In west Dorset, 3,283 people have contributed to the data and an estimated 244 active cases per million people.

It is lower in Weymouth and Portland where 1,349 people have contributed and there are no active cases. The same as Purbeck where 1,238 people have contributed.

In North Dorset, 1,774 people have contributed and there is an estimated 382 active cases per million people.

In East Dorset, 2,168 people have contributed and there is an estimated 336 active cases per million people.

South Somerset currently has the highest in the South West with 3,353 people contributing and 1,240 active cases per million people.

Epidemiologist Professor Tim Spector from King's College London is behind the study.

He said: “We are now starting to see the figures in the north creep up week on week.

“The numbers are still very small so we can’t say with 100 per cent certainty that Covid is increasing significantly but it does make us focus on those areas.

“To understand if these increases are significant or not, we need as many people as possible in these areas to be logging in the app.

“This week, the app also revealed that Covid symptoms and outcomes get worse in colder, less humid weather, which makes it even more important that we get this virus under control as we only have a month or two of warm weather left.

“Our data suggests that levels have bottomed out at around 2000 cases per day which is too many, so we all need to be conscious of the dangers and to continue to practice high levels of personal hygiene, wear a face mask, social distance and know all the signs of early disease.”

The data comes from 3 million users and 13,451 swab tests done between July 5 and July 18.

Their estimate matches up with the most recent figures from the Office for National Statistics.

During the 14-day period from June 22 to July 5, there were an estimated two new Covid-19 infections for every 10,000 people per week, equating to an estimated 1,700 new cases per day, the ONS said.
