But they also do weekly testing. And did surveillance testing at the end of winter break, which kept about 15% of the school's students at home for the first week back because they had covid.
This statistic was also consistent with LA Unified surveillance testing after winter break - about 15%.
Before winter break, some parents of 2nd graders had an indoor, maskless, holiday party. Apparently all the kids got covid. Then gave it to the teachers - all 4 2nd grade teachers were out of school with covid the week before winter break. But from what our school's testing showed, it didn't spread beyond that.
I do know of a couple families who did seem to get covid from their school though.
We have caught about 3 things over the past ~year, but none of it covid (as far as tests showed) and all of them had obvious non-classroom links.
Two of them were sick friends. And the third was probably when our 3 year old licked a trashcan at the zoo.
