We don't know that any of these teachers caught it in schools for sure, and no-one is ever going to investigate that because that would open up the DfE to legal actions, I'd have thought, especially now that UK schools are going back against the best practice for schools reopening. There are lots of teachers who are sure they caught it in school in March, though (anecdata).
The PHE study of schools in June/July showed that there was transmission in schools (in all permutations, student to staff, staff to staff, student to student, staff to staff etc). The headline is there were low numbers, yes, because hardly any children were back and they were doing SD.

My daughter has gone from (in June/July) under 15 children in a class SD, individual desks, in a small bubble with 2 members of staff (no kids got sick over 4 weeks) to being back a week, no SD, 30 kids in the classroom, bubbles which are 4x the size of June/July (roughly) and 4 kids are already off sick one week in.
It's not rocket science.
The reason rates have (largely) stayed low is because people have generally been doing SD, masks etc. THIS IS NOT HAPPENING AT ALL IN SCHOOLS. My kids - despite DD1 going back in June/July, haven't been ill since March. Now the littlest has a runny nose. We're not going anywhere else, she can only have caught it in school. I hope it's not coronavirus, but if kids are transmitting other illnesses in schools obviously they'll also be transmitting coronavirus.
