Analysis: Has COVID-19 been with us longer than we thought?

On 27 December last year, a 43-year-old man from Bobigny, a suburb of Paris, turned up at a French hospital with a dry cough, fever and trouble breathing. He had been sick for 15 days and had infected his two children, but not his wife, Dr Yves Cohen.
As part of a series of tests, doctors had originally collected samples to check for the flu using a polymerase chain reaction test — the same test used to detect the new coronavirus — which searches for bits of viral genetic material.
Instead, what they discovered months later, was that a sample taken just after Christmas tested positive for COVID-19.
The man had, therefore, contracted the virus nearly a month before France confirmed its first cases. But it’s still not clear how he was infected, as he hadn’t recently travelled.
Doctors can’t say whether or not he was France’s “patient zero.”

Genetic analysis
This case is part of ongoing evidence that COVID-19 has been with us all much longer than we first thought. Genetic analyses of the new coronavirus suggest that the virus emerged in humans in China in late November to early December 2019. While China’s official submission to the World Health Organisation (WHO) states that the first infection was recorded on 8 December, government data seen by the South China Morning Post newspaper seems to suggest that the first known case was actually observed on 17 November.
Anecdotally, we have all heard stories of friends or relatives who came down with severe flu in the winter, presenting many of the symptoms now associated with coronavirus, but most of them have not yet been tested.
But if that evidence is confirmed, it leads to an obvious question: why, then, did we suddenly see a peak in cases in different countries at different times? Why did the number of cases seemingly explode?
