What can different statistics tell us about coronavirus in Wales?
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, including positive tests, hospital cases, deaths, vaccinations and testing.
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.
It is only a snapshot of the virus out there as it relies on people asking for a test - or being tested somewhere like a care home - or not being asymptomatic..
But since the summer, when tests were fully available to anyone who thought they might have Covid, it is a good measure to look at how the virus is spreading and impacting on different parts of Wales.
Public Health Wales (PHW) said there was still concern about the number of cases, particularly given the numbers with the new variant.
Dr Giri Shankar, incident director, said although the overall case rate was at its lowest point in Wales since early October, it remained high in north-east Wales.
"The pressure on our hospitals is still severe and shows no signs of easing yet, so it is extremely important that everyone sticks to the rules and stays at home as much as possible," he said.
The new Covid variant will make up 90% of new cases in north Wales soon, it is estimated, with it "highly likely" to be behind higher levels in Wrexham and Flintshire. It is not known how it is spreading in south Wales. Thirteen confirmed cases involving the South African variant - 10 involving travel - and Public Health Wales is looking at whether there had been "wider community spread".
