Coronavirus symptoms heat map estimates cases in Cornwall now

A coronavirus ‘heat map’ now shows the UK’s top infection hotspots – and how many live cases are estimated to be in Cornwall right now, based on reported symptoms.

It has been produced using data collected by the Covid Symptom Study, an app that tracks people with coronavirus symptoms in the UK.

It relies on people over the age of 18 to download the app and record their symptoms, with more than four million people having downloaded in the UK.

The latest figures show that 28,049 people are currently predicted to have symptomatic Covid in the UK, as of 5am today.

In Cornwall specifically, there are estimated to be 423 active cases of coronavirus per million people, from 13,637 contributors.

Official government data states that as of 3.58pm today the total number of lab-confirmed UK cases sits at 296,377 since the start of the pandemic.

In Cornwall and the Isles of Scilly there have been 903 confirmed cases.

The Covid-19 Symptom Study app has been developed by health science company ZOE and it is endorsed by the Welsh Government, NHS Wales, the Scottish Government and NHS Scotland.

A total of 4,029,854 participants have so far downloaded the app and are using it to regularly report on their health.

App data is being analysed in collaboration with King’s College London researchers.

The company states: “By using this app you’re helping the NHS and contributing to advance vital research on Covid-19.

“By combining your reports with software algorithms, we are able to predict who has the virus and so track Covid infections across the UK and now other countries.

“Your daily reporting is also being used to generate new scientific understanding of the very different symptoms the virus causes in different people.”

This research is led by Dr Tim Spector, professor of genetic epidemiology at King’s College London.

He said the latest data showed that the number of daily new cases is no longer falling as in previous weeks, although this could be a temporary blip or due to the easing of lockdown and the amount of social contact slowly increasing.

He added that it needed all users to continue to log in, even if they had been ill and have got better.

The latest numbers are based on data from almost 3 millions users and 11,639 swab tests done between June 21 to July 4.
