Yes - my concern was that someone might already have gotten ********* and no longer be contagious but not allowed to compete because they will test positive before boarding the plane, as a person may test positive for up to 3 months after contracting the *****, even if they have done their quarantine and no longer be contagious. That could have eliminated a lot of Russian skaters, for example.
For the athletes who made it on the plane, the assumption would be that if they test positive in Sweden, it is a new infection, because they would have tested negative a multiple times in their home country before traveling. I feel bad for whoever it is that tested positive, let’s hope they and their team are okay.
