And interestingly one of the key takeaways from this peer reviewed article
journals.plos.org/plosone/article?id=10.1371/journal.pone.0237691 is that adherence and compliance is the major issue with mask wearing being effective, not the actual science behind it.
So thanks
*@Vintagevixen* for contributing to the increased risk for the rest of the children and adults in your dd's school.
Thanks for that link - I have had a read.
Couple of initial takeaways - its not an RCT, the gold standard of scientific research.
The authors themselves admit that no fit test, training or instructions will affect usage and therefore adherence and compliance.
Authors themselves admit that cloth face masks quality cannot be measured - the type that the majority of pupils will be wearing.
They actually exclude homemade face coverings from this article and specifically state that.
Lots of mathematical modelling - you would need an expert on code and modelling here to really speak on this.
They use only one epidemiological model - would have to then go back and look at this model and look for any potential flaws here.
Their conclusion only says that masks COULD help combined with SD and hand hygiene - they cannot state this definitively. Have they controlled for factors such as people relying on masks alone and ignoring SD? Lots of people do think masks are magic bullets.
They are modelling for the whole of the US, mot individual states - have they controlled for other factors eg T cell resistance to Covid, population density etc.
These are just a few things I have noted from a light read, will dive in deeper later.
