the Danes have with great probability brought coronasmitte on to, among others, Iceland, Sweden and Latvia.
this is The conclusion of researchers from Copenhagen University in a preliminary study, which has not yet been evaluated by external researchers in the field.
the Researchers have a mathematical background. The on Monday published a kind of coronavirus-the family tree, which can give an overview of how the virus spreads between people.
the Chart shows, among other things - as expected - that the infection in particular, came to Denmark from the ski resort of Ischgl in Austria.
But at the same time the danes also most likely brought the infection on to Iceland, Sweden and Latvia.
It tells the professor at the Department of Mathematical sciences Matthias Christandl, which is one of the researchers behind the study.
- We can see that the type of mutation, which is widely used in Denmark, shows up in Iceland, Sweden and Latvia. So it is natural that the mutation originated in Denmark and has since spread, he says.
the Researchers looked at publicly available data on coronavirussets dna. They can show how the virus has mutated - changed - when it is jumped from person to person.
- If you have all the mutations in a table, you can build a tree. It's like a family tree, where you can see who are close to each other, and who have 'ancestors' in common. It is the same with the virus, says Matthias Christandl.
the Researchers have analyzed about 700 publicly available Danish and 30,000 international sequences of coronavirussets genome, also known as the virus's genome.
With the family tree, researchers can then identify smittekæderne and exclude smittekæder theoretical. If it can be used in practice and help to beat the virus down, it will turn out, said Matthias Christandl.
- of course We hope that it can help to understand how the virus spreads. If two people have completely different virusgenomer, it is unlikely that they have infected each other. On the way, you can supplement kontaktopsporingen, he says.
the Study considered currently as a so-called working paper. It must first be evaluated by peers before it is scientifically recognised.
