Scientists and politicians have expressed relief but also some confusion about the apparent

decline in new daily COVID cases across the UK.

And to add to the complexity, different models for measuring cases are now giving different

indications of whether that decline even took place or whether it is even taking place

right now.

Let's run you through the different sources of data on this question.

The one we hear most about is from public health England.

They're the official statistics, people who have tested positive any one day.

It's what you hear on the news, it's what the government announced at their briefings.

Today, as we stand, there were 29,622 new COVID cases reported in the past 24 hours.

That's not a low figure.

It's also slightly up from 24,000 four days ago.

That was the lowest we've had in the last couple of weeks.

But as you can see from this graph, it is significantly down from seven days ago and

the seven day average is falling quite sharply.

As you can see, they're down 36% on the previous week.

We can zoom in a little bit now for good measure on those last couple of days just so you can

see where that did happen and where we might be having a slight uptick.

The benefit of public health England data and why we hear so much about it is because

it comes in real time.

And there are also all confirmed cases.

There aren't any estimations going on here.
