These figures are seven-day rolling totals for new cases adjusted for population (per 100,000 people). It is important to remember that though these figures are a useful guide they are just part of the story. If testing massively increases in one place there is likely to be a rise in confirmed cases. However, these figures are still a vital factor in Welsh Government and Public Health Wales decision-making.

Only four areas of Wales have seen an increase in Covid rates with places like Merthyr and Blaenau Gwent seeing almost a 50% reduction.

Below are the five areas where Covid has risen the fastest.

Growing fastest

Pembrokeshire

The rural county of Pembrokeshire has seen the largest rise in Wales at over 25%. As it is so sparsely populated just a few cases can wildly change the infection rate.

Cardiff

The Welsh capital has some of the highest rates in Wales at the moment with a 12% increase since the start of the month.

Powys

Powys has seen a small increase in cases but the infection rate remains below the Welsh average.

. Torfaen

Towfean has the second highest infection rate in all of Wales though it has only seen a small increase. Only the Vale of Glamorgan has a higher rate.
