I've seen the data but it doesn't match my anecdotal experience personally.
No one in my school caught covid between March and September, as far as we know.
Approx 75% of school staff at my infant school caught Covid in October-November. Almost all were most likely caught in school. The staff were socially distanced from one another, staff rooms weren't open, etc . We have classes of 30 and year groups of 90 - they were bubbled and adults SD where they could. Obviously in classrooms there were often 2 adults. Interestingly in many cases the TA and the teacher didn't catch covid at the same times. My role means I work across the whole school, so was mixing with 270 children weekly. Due to the age of the children there was no SD and no masks. Small Victorian style classrooms with small or limited opening windows, but open all day where they could be opened.
A number were ill enough to need longer than 2 weeks of work. Some have long lasting effects such as aching joints, fatigue, brain fog still now.
I was in hospital due to covid complications, and had 7 weeks off. It's been over 3 months now and I am still tired, my joints still ache though s steroid injection has helped (have arthritis and not being able to take meds with covid meant I had a huge flare up), have breathlessness and achy chest on increased exertion, brain fog, insomnia, etc. I've been left with very high blood pressure and now take two extra meds a day for it - no guarantee this was covid but I haven't had high blood pressure before, it's checked every 3 months and 3 weeks previous it was normal.
I don't deny teaching and school staff (important that LSA and TAs are included in these numbers, as well as general school staff, rather than separating them out which some of the statistics have done) have a lower risk of death and even hospitalisation, but I'm not hugely convinced by lower rates of catching it tbh. But that's marred by my own experience at school.
One of my family and friends, in other jobs, have caught covid that we are aware of (no other positive tests) bar my grandma before her death - she caught it in hospital. In dh's office of over 100 staff they've had 3 isolated cases, definitely caught outside of work.
So, yes the statistics may say this but my anecdotal,experience r]tells a different story,
