Scientists have tracked the mutation of the coronavirus

The first two were very common in Asia, however, almost never occur in Europe. Scientists suggest innate immunity of the Europeans.

Scientists from Cambridge, the UK and Germany have recreated the early evolutionary path of the pathogen that causes the disease COVID-19. Results the researchers presented using phylogenetic network and published in the journal PNAS.

A phylogenetic network is any graph used to visualize evolutionary relationships between genes, chromosomes, genomes, or species. It is noted that this can help to identify undocumented infectious sources.

The researchers also believe that understanding the mutations of a virus can help, particularly in vaccine development.

The scientists who conducted the study, used data from the genome of the virus around the world who gathered in the period from 24 December 2019 4 March 2020.

This was found three options SARS-Cov-2, which was designated “A”, “B”, “C”.

Type “A” is close to that which was found in bats. It was distributed in Wuhan city, however, was not the dominant variant of the virus. It also revealed Americans living in Wuhan. This variant of the virus was common in patients from the USA and Australia.

But the “main” type of the virus in the city of Wuhan was a type “B”. He basically dominated all of Eastern Asia.

“With” is “European” type of virus. It is this type of virus has found the first patients from France, Italy, Sweden and the UK.


Scientists say that a type “b” did not spread beyond East Asia.

From this we can assume that the Europeans might have immunological protection against this type or protection, which can be attributed to environmental conditions.

  • Type “A” is nearest to the virus that originated from bats and lizards.
  • Type “b” came from the type “A”. They are separated by two mutations.
  • The “C” in turn – “daughter” of type “b”.

This is not to say that the virus mutates very quickly.

At least slower than the flu.

For comparison, the SARS-Cov-2 has less than 25 mutations per year, at that time, as the flu virus has more than 50 mutations per year.

Scientists recorded the “sound” of coronavirus

Earlier it was reported that scientists have created an artificial virus that blocks coronavirus.
