Thanks. What I was going on about goes beyond this government or governments in general. There is bias that extends well into the medical and research communities against massively inconvenient truths. And there have always been massive gaps in disease surveillance, caused in part by the tendency to diminish the role of things that are only experienced as mild illnesses by the majority, certain age-groups etc. There are so many resulting contradictions, many of which children would have little trouble in figuring out if the issues were framed and explained properly.
We wont necessarily see nice, tidy conclusions coming from research into school outbreaks and spread during this pandemic. Because its hard to look at factors in isolation, and some of the bias will remain. Plus the roles of schools in epidemic spread extends well beyond the direct spread involving children and teachers, since when schools are closed the behaviour of adults is also changed (eg due to childcare issues).
Poeple that should know better cannot help themselves from equating mild and short Covid-19 illnesses in children with lower risk of transmission. Part of this is down to the same flawed logic we saw involved with all the denial about the role of asymptomatic cases. Naive ideas about transmission vectors that require a person to have coughy, sneezy etc symptoms to spread the virus in the most obvious ways that are in reality only a fraction of the full picture. And things that might actually be true and help to reduce the chances of a child spreading it to someone else, such as the possibility that they are infectious for less days than adults, are seized upon far too strongly. Its fine to point these things out but not in isolation, because for example a child may be infectious for less time but their level of viral shedding might be higher during the period where they are infectious. Have to consider both duration and intensity when trying to get the true picture.
Teachers are also used to inadequate measures being imposed from above, and have direct lived experience of how their profession exposes them to lots and lots of seasonal viruses during normal times. We used to joke with my mum about how she didnt get ill very often because her immune system had seen it all before via the reception age kids she taught for many years.
