Covid: Rhondda Cynon Taf shows 'exceptional' rise in cases

Rhondda Cynon Taf saw another 276 positive cases reported on Wednesday

There has been a dramatic rise in Covid-19 case rates in Rhondda Cynon Taf, in the latest figures published by Public Health Wales.

Nearly 800 people were tested in a single day - and a third of those tested positive.

Parts of the Cynon Valley over the past week have shown up as hotspots, with Penrhiwceiber eclipsing student areas of Cardiff for its case rate.

Council leaders have called the weekly rise a "great concern".

They do not expect to see improvements until the weeks after Wales comes out of the firebreak lockdown on 9 November.

There were a further 276 positive cases reported in RCT on Wednesday, with the case rate in the county having risen by 458.9 cases per 100,000 people over the past week.

RCT council leader Andrew Morgan said the cases announced on Wednesday were "exceptional" and were from people who picked up the virus over a week ago and had only just tested positive.

But he tweeted that the rise in the past week or so had been a "great concern".

Merthyr Tydfil is even higher on more than 487 cases per 100,000, with a particular hotspot on the Gurnos estate.

It came as PHW also reported 24 deaths across the Cwm Taf Morgannwg health board area - which includes Merthyr and RCT. - most occurred over the past seven days.

Dr Chris Williams, PHW incident director, said: "Rising case numbers are likely to result in rising hospitalisations and, sadly, to an increase in reported Covid-19 deaths."

Highest rates in the Cynon Valley

There have been 92 cases in the past week in Penrhiwceiber in the Cynon Valley.

Its case rate of 1,546 per 100,000 is even higher than the student areas of Cardiff.

Abercynon, Mountain Ash and the northern part of Aberdare are also high. Tonypandy East (655 cases per 100,000) is also in the worst 10 local areas of Wales outside student areas.

Positivity rates rise - especially in the south Wales valleys

Health officials in Wales have also been closely looking at positivity rates as one of the indicators of how infection is progressing.

In May, the World Health Organization (WHO) advised governments that, before easing lockdowns, the proportion of test results which come back should remain at 5% or lower for at least two weeks.

In Wales, that proportion of positive tests has increased sharply since August - in three of the areas with the highest positivity rates, they have reached 20% or more.

The Wales average for the most recent seven days is nearly 16%.

RCT, Merthyr Tydfil and Cardiff have been particularly high, at 20% or more.

Only Pembrokeshire has been below the WHO threshold.
