The coronavirus was delivered to the UK on a minimum of 1,300 completely different events, an necessary evaluation of the virus’s genetics reveals.

The examine, by the Covid-19 Genomics UK (Cog-UK) consortium, fully overturns the concept that a single “zero affected person” began your complete outbreak within the UK.

The evaluation additionally finds that China, the place the pandemic began, had a negligible influence on circumstances in the UK.

As an alternative, these preliminary circumstances got here primarily from European international locations.

The researchers analyzed the genetic code of viral samples taken from greater than 20,000 folks contaminated with coronavirus in the UK.

Then, like a big model of a paternity check, geneticists tried to rebuild the large household tree of the virus.

This was mixed with worldwide journey knowledge to get to the origins of the UK epidemic.

They discovered that the UK coronavirus epidemic had no origin, however a minimum of 1,356 origins. On every of these events, somebody introduced the an infection to the UK from overseas, and consequently, the virus started to unfold.

“The shocking and thrilling conclusion is that we found that the epidemic within the UK was the results of a lot of separate imports,” stated Professor Nick Loman of Cog-UK and the College of Birmingham.

“He was not a zero affected person,” he added.

The examine confirmed that lower than zero.1% of these imported circumstances got here instantly from China. As an alternative, the UK coronavirus epidemic was largely began by journey from Italy in late February, Spain in early and mid-March, after which France in mid-end of March.

“The large shock for us was how easy the method was, the speed and supply of introduction of the virus modified quickly over the course of some weeks,” stated Professor Oliver Pybus of the College of Oxford.

The circumstances that began with outbreaks got here primarily from Europe

80% occurred from February 28 to March 29

“This occurred later than we would have anticipated,” added Professor Loman.

The examine estimates that 80% of these preliminary circumstances arrived within the nation between February 28 and March 29, the time when the UK was debating whether or not it must be closed.

After this level, the variety of new imported circumstances decreased quickly.

The primary dates again to early February, however there could also be even earlier circumstances that the evaluation was unable to detect.

The examine additionally says that the controversial soccer match between Liverpool and Atlético de Madrid on March 11 most likely had little influence on the introduction of the virus into the nation.

An estimate of three,000 Followers flew in from Spain to observe the sport, however there have been 20,000 folks flying in from Spain on daily basis in mid-March.

“[It] reveals that particular person occasions like soccer video games most likely made a negligible contribution to the quantity of imports on the time, “says the examine.

Every of the imported circumstances started a series of transmission by which the virus passes from one individual to a different, to the following, and so forth.

Nonetheless, the examine reveals that the blockade has massively interrupted the unfold of the virus.

“If there’s excellent news right here, these broadcast chains have been and are being suppressed and extinguished on account of social estrangement and we proceed to see that now,” stated Professor Loman.
