Covid-19 in Wales: What do the stats tell us?
What can different statistics tell us about coronavirus in Wales so far?
We seem to be bombarded with different measures, but what do they mean and how does Wales compare with other parts of the UK?
Here, we try to answer some of the questions and explain what the different measures are and also give some of the most recent figures.
Where in Wales are the most cases?
Case rates can tell us how many people with Covid-19 symptoms are presenting themselves for tests which then come back positive.
Public Health Wales (PHW) said recent days have shown "an alarming rise" in case rates across the country.
The case rates compare different areas and sizes of populations - 14 council areas again hit their highest figures on Thursday.
Half of the 22 councils still have case rates of 500 cases per 100,000, and seven of them make up the seven highest across the UK.
As we can see from the map, only the north-west corner of Wales has Covid case rates at comparatively low levels.
How many people are infected?
The latest Office for National Statistics (ONS) infection survey estimates the proportion of those testing positive has risen in recent weeks
in Wales.
It took throat and nose swab tests from more than 19,400 people at random in Wales over six weeks.
From the results, it can estimate that 25,600 people in Wales had Covid-19 in the week to 4 December, 7,500 more than the week before.
This is one in 120 people or 0.84% of the population.
ONS says "our modelling suggests that the percentage of those testing positive has increased in recent weeks in Wales."
The survey found a total of 142 positive tests, in 122 people from 99 households over six weeks.
Similar surveys suggest cases have fallen in England (one in 115 people estimated to be infected) while falling back, although rising
in London. In Northern Ireland it was estimated at one in 235 people and falling. Positivity rates in Scotland were stable
(an estimated one in 120 people).
