A German study of the country’s death rate could mean that up to 7.9 million Britons have been infected with the coronavirus.
Research work from the University of Bonn suggests that the true total infection may be more than 40 times higher than official figures in the UK and ten times higher in Germany.

The researchers studied the city of Gangelt, one of the most affected in Germany, to calculate that coronavirus infections have a death rate of 0.37%.
From this figure, scientists extrapolated that Germany must have ten times as many infections as the first, potentially 1.8 million.
Official figures record 166,424 infections and 6,993 deaths, but to get the figure of 0.37 percent you would have to have an infection count of nearly two million to account for the number of deaths.
The author of the study, Professor Hendrik Streeck, said that the total number of data can be “assumed” with confidence.
And then this same work applied to Britain, taking the latest official figure of 29,424, would mean that the total infection would have to be as high as 7.9 million compared to the official figure of 194,990, more than 40 times higher.
This does not take into account possible unrecorded deaths in the equation.
With the death toll compared to the potential number, that would mean that millions of Britons may have had the deadly virus and survived.
Infections are believed to be underestimated due to a variety of reasons, including lack of evidence and asymptomatic cases, and the coronavirus may even hit Europe in early November.
Many other factors also affect mortality rates, which may not be extrapolated in all countries, such as lifestyle, and countries are also at different stages of the pandemic.
Germany is known to have carried out widespread tests since the early onset of the outbreak, and large amounts of contact tracing to locate other cases.
This is why the official infection total is so high along with the relatively small death toll, with other European nations such as Britain, France, Italy and Spain all close to the gloomy milestone of 30,000.
The German study has only published its preliminary results, which have not yet been peer-reviewed for publication in a scientific journal.
Professor Streeck and co-author Professor Gunther Hartmann said the results serve as a reminder of the dangers of infection by unidentified carriers of the virus as nations in Europe begin to ease their blockades under the threat of a second wave.
Professor Hartmann said: “The results may help to further improve models for calculating how the virus spreads. Until now, the underlying data has been relatively weak.”
The team analyzed blood and nasal samples from a random sample of 919 people living in Gangelt to arrive at a death rate of 0.37%.
They also found that about one in five of those infected showed no symptoms of the virus.
Applied to the UK’s suggested figure of 7.9 million, that would mean that up to 1.58 million carriers are completely unaware that they had the coronavirus.
Martin Exner, director of the Institute of Hygiene and Public Health at the University of Bonn and co-author of the study, said: “The fact that apparently every fifth infection progresses without noticeable symptoms of the disease suggests that infected people who clear the virus and that therefore they can infect others and cannot be reliably identified on the basis of recognizable symptoms of the disease. “
He added: “Every supposedly healthy person we find can carry the virus without knowing it. We must be aware of this and act accordingly.”
As the document is reviewed by other scientists, the researchers said the study explains the need for continued social distancing.
Goettingen University experts released a study last month that suggested national totals should be in the millions.
They estimated that the United Kingdom already had two million people infected at the end of March, while they estimated that Spain had six million and the United States had 12 million.
Accurate numbers on infections are very difficult to trace, and that is what makes the decision to ease the blockade even more difficult for ministers, as unknown carriers can spread a devastating second wave.
More than 1.2 million coronavirus tests have been conducted in the UK, but questions have been raised about if it has been enough
First Secretary Dominic Raab reminded the British today that the next phase of the pandemic “will not be easy” and urged people “to have no illusions” about easing the blockade.
Britain will receive an update on any easing of the measures when Prime Minister Boris Johnson addresses the nation on May 7, and two of the government’s five key tests are believed to have been met before the measure.
