We know very little about the new viral variant “Delta Crown,” which is a mixture of Delta and Omicron, says Espen Nakstad, assistant director of health.

Aftonbladet He wrote on Saturday that vaccine researchers at Karolinska Institutet believe an alternative is likely to be found in Sweden.

They don’t know how contagious the variant is, or whether it will outgrow Omicron.

When there is as much contagion in a community as there is now, Nakstad is not surprised by the emergence of new virus clusters.

“Now it is clear that this occurred in that person and the same person infected with both the delta variant and the omicron, spreading a new SARS-CoV-2 virus with genes from two variants to the other,” Nakstad wrote in an email to NTB.

He does not know that the alternative has been proven in Norway. However, it has been proven in Denmark and France.

As early as January, researchers in Cyprus thought they had found a new type of halo that was a mixture of Omicron and Delta. However, the International Family Health Organization believed that it was possible revolve around a lab error.

Significant change in genetic material

Such a change in the genetic material of the virus is much greater than the changes that occur when the virus changes step-by-step through common mutations, says Nakstad.

It is not certain that ‘crown delta’ has pathogenic properties that significantly distinguish it from the omicron variant, nor is it certain that it is more contagious than omicron. It’s clearly so contagious, says Nakstad, that it has spread and been detected in several places.

He points out that new viral variants are expected in the future, and that the most important thing is that they do not cause more serious diseases and that the vaccine prevents them.
