Well, I'm having a crash course in how test & trace works here, in Norway. Half of my son's year are in quarantine, now, from yesterday.
They had been allowed limited contact between two classes until Wednesday, when the measures were tightened again. Two classes on the same year, one of them my son's, used the gym during the same time (but not together)on Tuesday, and someone in the other class tested positive on Wednesday.
If he has a negative test (scheduled for later today), the rest of use are allowed normal, socially distanced, activity, while he quarantines. If his test is positive, we are all in quarantine, and have to get our own tests. The chances are small, as it does not seem he has been in direct contact with the child who tested positive, but it's possible if they turn out to be a super spreader, or something.
There are similar situations on the years below & above his, so 3 years are all on home school (instruction on Teams) at least through Easter.
We've had a letter home that the British (aka Kent) variant is in community transmission in our area, and that it not only is more transmissible, but it is more likely to infect younger people, and transmits much more easily among children than the previous variants
They thought a few weeks ago that they had limited the spread of the British variant in our area, but it seems that people travelling for winter half term (!?!) brought it back into the community. They have not said where people went, but if they left the country, they should have quarantined upon return, so either they broke the rules, or brought it here from another part of Norway.
