.@NAOorguk @CommonsSTC - can you investigate the delays in today's Covid reporting? If it's just a delay in reporting, that's one thing, but if these are delays into NHS Test and Trace system, that's another thing entirely. Would be good to see age/source of delayed cases
It is important to understand the reason for the delay. If this is a reporting delay, that is bad enough, but if there have been delays in putting these cases into the NHS Test and Trace database, that can have serious implications for spreading the disease
We also need to know if there is commonality in the source of these cases. We have seen that private testing and university testing has been carried out, and it is still not clear how these results (both positive and negative) are being routed into the DHSC system.
Will be discussing the testing issue on Sky News tomorrow at around 6:10am. Which is very early. Best get some sleep.
Delays in reporting can also pose problems for modelling of R as well as well as the dynamics across the population (age groups), hospitalisations, ICU capacity etc.
This chart shows the delays for the cases reported yesterday (source: PHE). Note there is a legal requirement under the Health Protection (Notification) Regulations 2010 for these cases to be notified within a time limit. Not sure whether this is 3 or 7 days.
