When I say 'susceptible' I mean 'catch it more easily'.
And I really do mean there just isn't data at the moment.
The far higher incidence amongst 0-19 year olds really may just be down to the fact it is more infectious, schools are the 'big' thing that is open, therefore you will find more incidence of this new virus amongst those who frequent schools.
At present, there appears to be nothing to suggest that this variant poses any greater a risk to children/younger people than the previous strain.
It's just that there's more of it, and it's spreading mainly amongst 0-19 more (probably because of schools).
But the data really is still being interpreted.
Having said all that, everything really does point to schools being a major factor in the transmission of a very infectious new strain of Covid, particularly in Lindon and the south-east.
Given that, it seems just bonkers not to try and do everything to create a firebreak.
It must seem very weird for those parts of the U.K. that aren't affected - but, likewise, from here in London it seems scarcely believable that elsewhere life is 'normal', without people around you testing positive. 🤷♀️
