Kings College tracker app data released – First Minister states ‘nobody at all actually knows’ true number of cases for people living in or visiting the wrexham area

The First Minister has said the 1,100 tests a day in Wales shows a ‘fraction’ of the current cases of the coronavirus.

We asked a question to the First Minister at this afternoon’s daily press conference after a new crowd sourced data set was released, mapping COVID-19 symptoms across the UK.

The data release is by the COVID symptom tracker project that has been created by doctors and scientists at King’s College London, Guys and St Thomas’ Hospitals working in partnership with ZOE – a health science company. The research is led by Prof. Tim Spector, professor of genetic epidemiology at King’s College London, and currently has around 1.8million people submitting data across the UK.

The data collected includes information on a persons health status and lifestyles, as well as any vulnerability issues. The information also tracks symptoms in an attempt to log and be more alert to to early symptoms. The information is being shared to ‘bonafide researchers’ as well as publishing updates to the public.

Lead researcher Professor Tim Spector said: “When combined with other symptoms, people with loss of smell and taste appear to be 3 times more likely to have contracted COVID-19 according to our data, and should therefore self-isolate for seven days to reduce the spread of the disease.

“This urgent research is only possible thanks to the 1.8 million citizen scientists logging their symptoms every day.

“This also gives us an evolving map of the UK of where symptoms are occurring two to three weeks before a strain on the NHS, which is why it’s vital to continue logging your health and symptoms, even when you feel completely healthy, and encourage others to use the app.”

The localised data shows for North Wales:

  • Wrexham has 2354 contributors and the data estimates 4.67% with symptomatic COVID-19
  • Flintshire has 2555 contributors and the data estimates 4.94% with symptomatic COVID-19
  • Denbighshire has 1594 contributors and the data estimates 3.32% with symptomatic COVID-19
  • Gwynedd has 1875 contributors and the data estimates 4% with symptomatic COVID-19
  • Ynys Môn has 1039 contributors and the data estimates 5.2% with symptomatic COVID-19
  • Conwy has 1946 contributors and the data estimates 3.49% with symptomatic COVID-19

People can also have COVID-19 and have no symptoms, but still able to pass it to others.

If the estimates are correct the population of areas could mean 3500 people on Ynys Môn could be showing COVID-19 symptoms, and nearly 7,000 in Wrexham.

Today we asked the First Minister Mark Drakeford, “The widely used COVID-19 symptom tracker app indicates there could be tens of thousands of people with symptoms in North Wales. Does that data reflect information Welsh Government is seeing?”

The First Minister said, “I said in my introductory points that while we know through testing the number of people who identify as having coronavirus, that will be a fraction of the actual number because of the way it’s circulating in the community.

“When we quote these figures, nobody should believe that it is only those people have coronavirus. I think it’s important not to be too specific about how many people are out there, because nobody at all actually knows.”
