The person must have traveled from the UK to celebrate Christmas in Södermanland and arrived in Sweden on 20 December.

The person experienced symptoms when he arrived at the family's house and tested himself the next day.

- It is a person who went to Sweden to celebrate Christmas with family.

The person fell ill when he came to the house in Södermanland, says region Sörmland's infection control doctor Signar Mäkitalo.

The test result turned out to be positive and on the second day, the Public Health Agency confirmed that it is the variant of the coronavirus that is spread in the UK.

- It was the mutated virus.

We have sampled the others who were in the house and those samples have so far been negative.

In my opinion, the person has behaved in an exemplary manner during the trip to the house and I assess the risk of infection spreading during the trip as low, says the infection control doctor Signar Mäkitalo.
