I've had to isolate 6 times I think so far due to myself or family having symptoms.
I have 2 kids in senior school and they have all been since they returned to school.
My DD's school seem to be super strict, they nearly sent her home once as she complained she was cold in class, and was the only one c/o being cold - as it is they removed her from the class for half the day till they decided to let her back in.
The one time she did have covid I almost did not test her as she had a temperature for about 6 hours and that was it (and this was the 3rd time in as many months I was going to have to isolate) - no other symptoms - negative on LFT - but ended up getting her a PCR just in case - and she was ruddy positive.
It seems from my workplace, those with kids at school have certainly had to isolate more then those without.
I am currently isolating for myself, after a positive LFT - they got rid of the nearest test centre by us just before xmas so if I had to get a postal PCR it would be a pain, and it took over 6 days to get the result from a postal last time. When I could go to the walk in without fail I got the result in about 20 hours.
I could arrange a PCR through work as I work for the NHS but again this is only a drive through service.
I am utterly fed up with it all now.
