NRK showed still images from the incident to Karlsson.
- Do you want to make me nervous?
Karlsson asks the Norwegian reporter, who replies that it wasn't meant to be, but continues to ask if the hugging after the races is over now.
- Yes, we have to keep our distance from it now, says Karlsson.
When Karlsson later met SVT Sports broadcaster Rikard Lann, it was the first time during the tour that she used a mouth guard in connection with interviews.
But she played down the covid outbreak, where a Norwegian leader was also infected earlier this week.
- No, we know that corona circulates in society and here too, so it's nothing new, says Karlsson to SVT, who sympathizes with overall third-place finisher Kalvå, who is affected for the second time.
- It's super boring for her.
She got corona even before the Olympics, so it hasn't been kind to her, says Karlsson.
Kalvå shared a room with the Udnes Weng sisters
Kalvå feared covid when it started to take hold in the Norwegian team at Christmas time and expressed it as a "trauma".
During the time on the tour she shared a room with the twin sisters Tiril Udnes Weng, second overall, and Lotta Udnes Weng.
Tomorrow, a sprint in Val di Fiemme awaits the riders.
None of the other Swedish riders have anything to do with the total, which would open the way for Karlsson to drive tactically.
- It's not something we've talked about yet, but we're going to have a meeting tonight.
I don't think you can do much and you shouldn't make the situation worse.
It's not strange, it's just out and driving as usual, says Karlsson about his thoughts before the sprint.
Karlsson is in an excellent position to win the Tour de Ski the first time she completes the competition.
- I only see opportunities.
Not trying to float away and think about the end right now.
The focus is on the sprint.
The tour ends with the hill up Alpe Cermis on Sunday.
