Only 3,300 to 3,800 people are catching the coronavirus each day in England, according to official statistics and an app run by scientists.
Estimates from King’s College London’s COVID Symptom Tracker app suggests the number of people getting infected has plunged by a quarter in just a week to 3,391 each day.
And the Office for National Statistics, in a separate report, has predicted that around 3,800 people are catching the virus each day – some 26,900 per week.
Both estimates represents drops from earlier statistics and show the virus is continuing to fade away in Britain.
The researchers, working alongside health tech company ZOE, have been collecting reports of symptoms and test results from a million UK citizens.
Last week they used this data to estimate that there were 4,942 people catching the virus every day in Britain, and today they said this appears to have dropped 26.9 per cent to 3,612. The figure was higher than 11,000 per day a month ago.
Almost all of those new infections — 3,391 — are occurring in England, the team said, along with 118 per day in Wales and 102 in Scotland.
The estimate does not include Northern Ireland or care homes, where the virus is still thought to be spreading, meaning the true rate could be much higher.
Office for National Statistics data, which is based on regular testing of a representative sample of the English population, puts the daily estimate at 3,800.
A report published today said 26,900 people are thought to be getting infected with the virus each week and that around 33,000 have Covid-19 at any one time.
The ONS said only around one in 7,000 people now have the illness and that ‘the number of people in England testing positive has decreased since the study began on 26 April’. It added, however, that the decline appears to have slowed recently.
Data from the COVID Symptom Tracker app suggests there are now only around 3,400 new cases of Covid-19 appearing each day in England, down from more than 11,000 per day a month ago

Professor Tim Spector, an epidemiologist at King’s, has been running the COVID Symptom Tracker app project since March.
He said today: ‘These latest figures are good news for the UK.
‘We are seeing the R value holding stable below 1 and at the same time we are seeing the number of new cases continuing to fall across the UK.
‘In most areas the rate of new population cases is less than one in ten thousand.
‘With the changes in the regions, the gaps we were seeing just a few weeks ago are closing, particularly the North-South Divide.
‘We still aren’t seeing the numbers coming down in the same way in London and the South East, where we need extra vigilance, especially with shoppers heading back to the high street and social interactions between wider family groups increasing.’
The team running the mobile app ‘COVID Symptom Tracker’ have been collecting data from people self-reporting symptoms and test results for months.
The data in this week’s update was taken from one million people’s self-reports on their own health, and the results of 17,984 swab tests taken by app users.
People are asked to log on regularly to report whether they have any signs of illness or whether they feel healthy.
They are asked to get tested if they have symptoms that may be linked to Covid-19, and to report the results of the test.
Because of this, the app cannot reliably track the number of people who are catching the virus but not developing symptoms, which may be thousands more.
The Office for National Statistics, the governmental stats department, collects data differently and uses regular testing of a representative sample of the population.
ONS experts then estimate the levels of infection based on how the proportion of that group testing positive changes over time.
Last week the ONS suggested that 4,514 people per day were catching the coronavirus and approximately 33,000 people had it at any time in England.
The daily estimate has dropped this week, to 3,800, but the total number of people thought to be infected remains at 33,000 – 0.06 per cent of the population.
But the drawback of the ONS data is that it does not include people who are diagnosed in hospitals or care homes.
Dr Paul Birrell a researcher at the University of Cambridge, who has been working with Public Health England on different predictions, said none of the estimates are perfect.
He explains: ‘The symptom tracker tracks only symptomatic infection. You would need to add the asymptomatic proportion onto this to get a number comparable with our estimate. Unfortunately, this proportion isn’t well known.
‘Analysis of data from the cruise ship outbreaks suggest this is about 50 per cent, whereas the ONS study says that as many as 70 per cent are asymptomatic.’
The COVID Symptom Tracker team have also used their data to estimate the reproduction rates of the virus in each region of the UK.
The R rate indicates how many people each infected patient passes the disease on to, and must remain below 1, on average, in order for the outbreak to shrink.
Professor Spector and his team worked out the R by comparing its changing estimates of numbers of people with the disease with the time it takes for cases to spread.
They estimate that the R value for the UK and England as a whole is 0.8.
In London and the South of England it’s predicted to be 0.9, while it is 0.8 in the Midlands and 0.7 in the North and East.
The Government’s official estimate suggests that the R is between 0.8 and 1.0 across England and 0.7 – 0.9 over the whole UK.
