Schools are a challenging one - I've seen stats banded about saying things like "30% of cases originate in schools" but I think they're misrepresenting. The best stats I've found are the weekly public health england ones (not Scotland but no reason to believe that proportionately they'd be dramatically different). These give a breakdown of acute respiratory incidents reported to public health teams, and the numbers they quote are two types; suspected incidents reported (not necessarily any confirmed cases linked to the setting) and "The number of incidents in each setting with at least one laboratory confirmed case of COVID19"
Now;
- by definition any child who attends school and gets covid will, it seems, meet this standard.
- this only includes those cases which are linked to a particular type of institution/setting; so any percentages extracted from it aren't really correct as they're excluding all the cases with no link to settings. So, those in people's homes for example...
- the presence of a link to a setting does not mean that it was transmitted within that setting
-they lump all educational settings together
I think by sheer weight of numbers and the way the analysis is being done educational settings will come out of this looking bad because of the number of people who attend them.
Parent A gets covid. Transmits it to child B, who has no symptoms but gets tested. Positive test. That's an incident linked to an educational setting.
Last week in England there were
"327 incidents were from educational settings where 252 had at least one linked case that tested positive for SARS-CoV-2"
Google suggests there are
24,323 schools
106 universities
at least 240 colleges
and probably a bunch of others not included. So approximately 1% of educational institutions had at least 1 linked covid cases, which may or may not have been acquired or transmitted within the setting
There's about 15k care homes - their numbers were 311/210 by comparison, and there will be far fewer people who can be classed as linked to a care home (as most care homes are significantly smaller than your average school). The care home population for England seems to be about 418k whilst there are 8.82 million pupils in schools, and over 2 million at university.
The way these percentate of infections has been banded about is ridiculous
