I agree @Chaotic45 - it does feel like a critical time to have a data "gap".
Although I suspect its not only about data / lab resourcing issues over the festive period.
I suspect, its also owing to human behaviour. People with mild symptoms were probably less likely to get tested over 24/25/26 in the hope it was a false alarm and they might shake it off.
Regardless, it will mean that data can't be entirely taken at face value at the moment - you need to kinda dig into it a bit or make a mental adjustment to it.
I'm really keen to understand the transmission amongst school aged children so greatly welcome the discussion above. This thread has honestly been a godsend to me in 2020.
And happy new year to everyone
