New figures released by Public Health Wales reveal the scale of the coronavirus outbreak in every area of Wales, and how it compares to parts of England.
The latest figures show that Newport has the highest number of incidents per 100,000 people anywhere in the United Kingdom, with over 277 diagnosed cases per 100,000 population.
In comparison, London's worst-affected Brent council has 229 cases for the same number of people - although this may be because London has done less testing.
Cardiff comes in second place behind Newport for highest percentage of cases according to the population in Wales, with over 187 cases per 100,000 people.
Of the top five local authorities worst affected by the coronavirus outbreak in Wales, four are within the Aneurin Bevan University Health Board area. The health board has made headlines numerous times over the past week for the high number of cases recorded there.
These figures break down the picture according to local authorities for the first time since the Welsh Government stopped publishing the stats on a daily basis several weeks ago.
It reveals that the outbreak has affected all of the Aneurin Bevan health board area, which covers Newport, Caerphilly, Blaenau Gwent, Torfaen and Monmouthshire.
The Public Health Wales figures also reveal demographics of confirmed cases for the first time, with the highest number of cases appearing in the 50-59 age bracket, followed by the 40-49 and 30-39 age brackets. Far more women are also being diagnosed.

Out of all the local authorities in Wales, Cardiff has carried out the most tests (2,170), followed by Rhondda Cynon Taf, Swansea and Newport.
Newport has the highest proportion of positive results from Covid-19 tests, with 48% of tests coming back positive. The proportion of positive test results in Cardiff is slightly lower, with 31.5% of coronavirus tests coming back positive.
The results of these tests also show that the Aneurin Bevan health board area has seen the highest proportion of positive results. After Newport, the next four local authorities with the highest number of positive results are Torfaen, Caerphilly, Blaenau Gwent and Rhondda Cynon Taf.
This data also allows a direct comparison with English councils. The worst affected council in England is Brent in London, with over 229 cases per 100,000 people. This is followed by Southwark at nearly 216 cases per 100,000 people, and Lambeth at nearly 206.
Outside of London, the English council with the highest number of confirmed cases is Sheffield with 153 per 100,000 inhabitants.

This means that Newport is statistically the the most heavily affected local authority in the United Kingdom in terms of diagnosed coronavirus cases, although it is still hard to make a true comparison on how acutely each area is affected until statistics on the number of deaths, hospital admissions and critical care bed occupancy are released in Wales and in England.
Mortality stats for England suggest that 11.39% of the 42,990 people diagnosed with Covid-19 have died, compared to 5.52% of the 3,499 people diagnosed in Wales.
As the virus is equally dangerous in both countries, this suggests that Wales has been twice as successful in diagnosing coronavirus cases than England and that the highest rates of hospital admissions and people in critical care are likely to be in London.
However on the number of deaths, hospital admissions and critical care bed occupancy for each specific health board and local authority are not routinely published.
A spokesperson for Public Health Wales has said: “We are not currently confirming data on the number of deaths per health board due to the relatively small numbers involved and the need to maintain patient confidentiality. This will be reviewed on an ongoing basis.”
