The SARS-CoV-2 virus, which has caused the COVID-19 pandemic, has evolved and divided into two different groups, according to the latest study of the National Institute of Hygiene and Epidemiology.
Professor Lê Thị Quỳnh Mai, deputy director of the institute said the scientists had conducted the study after it cultivated and isolated the virus since Việt Nam recorded the first people positive with the virus.
Mai said at first, patients mostly returned from Asian countries but now the patients mostly had been in European countries.
The virus Việt Nam isolated in COVID-19 patients coming from Europe was found to be different from the virus in COVID-19 cases found in Asia, she said.
The institute's discovery followed the general trend of the world, she said.
Mai said that so far the study had yet to show which of the two was more infectious or stronger as the spread of the virus also depended on the environment, geography and person infected, but detecting the changes of the virus would aid vaccine production.
Previously, Mai and her colleagues isolated the virus in early February, making Việt Nam one of the first four countries around the globe that isolated the new strain of coronavirus.

You look like Bad Pitt? LOL. I agree.

Nice shot, Captain!
More than two
The Rs and the Ds. At each others’ throats, now and forever.
WuFlu is an RNA virus, and those mutate like crazy. And not all mutations are bad news for people.
That said, I don’t think I’ll wait for more eggheads to weigh in on if it’s true and what it means. :-)
bttt
8 strains of the coronavirus are circling the globe. Here’s what clues they’re giving scientists.

5 Mar: UK Telegraph: Coronavirus has mutated into more aggressive disease, say scientists
Coronavirus has evolved into two major lineages and it is possible to be infected with both, a new study shows
By Sarah Knapton
Researchers at Peking University’s School of Life Sciences and the Institut Pasteur of Shanghai, discovered the virus has evolved into two major lineages - dubbed ‘L’ and ‘S’ types.
The older ‘S-type’ appears to be milder and less infectious, while the ‘L-type’ which emerged later, spreads quickly and currently accounts for around 70 per cent of cases.
Genetic analysis of a man in the US who tested positive on January 21, also showed it is possible to be infected with both types...

not a great paper, and no source given for the 100-150 covid19 mutations, but worth a read:
6 Apr: Irish Times: Genetics shed light on origins of Irish strains of Covid-19
Strains identified in Dublin, Cork and Limerick linked to Birmingham, Boston and Copenhagen
by Ronan McGreevy
Since the Covid-19 virus strain was first identified in early 2020, scientists have been able to track its progress around the world.
The virus is very slowly evolving, but in making copies of itself in its human hosts, it can introduce occasional errors in its genome sequence to make a different sequence.
This means that strains are almost identical but, crucially, differ by the tiniest amount...
Scientists around the world have analysed more than 2,500 publicly shared Covid-19 genomes and identified 100-150 mutations...
They have been able to identify that the outbreak in Washington state, which was one of the earliest places in the United States to record coronavirus cases, came from China in early January and a second strain came from Europe.
The results are available on a public access platform called nextstrain.org...
The strain identified with Cork is the same as that from Boston which is understandable given the strong Irish links with the city...
The first 13 confirmed cases of coronavirus in Ireland were all people who had returned from northern Italy or who had contact with such people...

Good enough :)
Interesting, though it doesn’t tell me anything I wouldn’t have guessed, and I’m so CV’d out that how an Italian guy evaluates his Puerto Rican GF when it comes to pasta seemed even more interesting.
