After a major corona outbreak in Trondheim in Norway last week, where 1000 people have been quarantined and 24 people fell ill according to Norwegian Dagbladet, the local chief physician Tove Røsstad sent virus samples to the National Institute of Public Health.

On Monday, the same chief physician in the Norwegian media said that the first test results show that the virus is a variant that the National Institute of Public Health has not previously registered.

- What we have experienced is that the virus spreads more easily, that you do not have to be so close to others for a long time to become infected, says Tove Røsstad to Norwegian TV2.

All living things mutate

But according to experts that SVT Nyheter spoke to, the information from Norway is not very astonishing.

- Not at all, it is completely expected.

This is just a variant of many who are spinning around the world right now, says Niklas Arnberg, professor of virology at Umeå University.

Why does it happen?

- Everything with genetic material mutates.

Even us, it's a part of life.

It is random changes that take place and it is thanks to them that we can adapt to new conditions, says Niklas Arnberg.

No serious change

Jan Albert, professor of microbiology and infection control at Karolinska Institutet, also does not react very strongly to the news from Norway.

- There must be clearer evidence, than what I saw today, to say that there is something different about this virus.

How?

- If it is clear that the virus has new properties or if there are clear signs of another disease picture.

Then we have evidence of a change that is important, says Jan Albert.

Jan Albert does not see the fact that very many people were infected at the same time in Trondheim as proof of a change in the virus.

- I think it's more about the environment in which these people lived.
