A LOCAL lockdown is set to come into force in Wales today following a "significant rise" in coronavirus cases.

People in the county burough of Caerphilly will not be allowed to enter or leave the area without a reasonable excuse when the restrictions come into force from 6pm on Tuesday, the Welsh Government said.

Everyone aged over 11 will be required to wear face coverings in shops – marking the first time this will be mandatory in Wales.

Meetings with other people indoors and extended households will not be allowed, while overnight stays will also be banned.

There have been 133 new Covid-19 cases in Caerphilly county borough over the past seven days, equivalent to a rate of 55.4 cases per 100,000 population.

This is the highest rate in Wales and one of the highest in the UK – and case numbers are expected to rise, the Welsh Government said.

Health minister Vaughan Gething said: “We have seen a significant rise in cases in Caerphilly borough over a very short space of time, which are linked to holiday travel abroad and people socialising indoors and not following social distancing guidelines.

“A lot of these cases are in younger people and thankfully, at the moment, most of these are mild.

“But coronavirus is now circulating in the community and it’s only a matter of time before we start to see more serious cases, which need hospital treatment.

“We need the help of everyone in Caerphilly borough to prevent the increasing and onward spread of coronavirus.

“We can only bring this local outbreak under control if everyone pulls together and follows these new steps.

“If we do not see cases falling, we may need to take further steps to bring this local outbreak under control.”

Community testing was introduced in Caerphilly at the weekend.

On Saturday, 450 people were tested and 19 had the virus – giving a positivity rate of 4 percent, which indicates that Covid-19 is circulating in the community.

A similar number of people were tested on Sunday, with results expected shortly.

Travel restrictions included in the lockdown mean people cannot enter or leave Caerphilly County Borough Council area without a “reasonable excuse”.

This includes work, if people are unable to work from home, as well as making a compassionate visit to a loved one or to provide care.

People will only be allowed to meet others outdoors, with indoor meetings and gatherings restricted.

Caerphilly Council has already introduced measures such as suspending care home visits, and introducing weekly testing for care home staff, in response to the increase in cases.

Philippa Marsden, leader of Caerphilly Council, said: “We need to create a break in the cycle of infection we are seeing in Caerphilly borough at the moment and unfortunately that means introducing new, tougher restrictions.

"If we do not see cases falling, we may need to take further steps to bring this local outbreak under control

“I would urge everyone living in the area to follow these new measures; to follow the social distancing guidelines and to wash their hands regularly.

“If we all work together, we can bring this outbreak under control and reduce cases of the virus.”

The new measures will be enforced by the local authority and police.

Numerous schools have been affected by coronavirus since the start of the autumn term, including one class of 21 pupils at a primary school in the Caerphilly area being told to self-isolate for 14 days.

Dr Giri Shankar, of Public Health Wales, appealed to everyone in the Caerphilly area to use a local testing unit at the town’s leisure centre if they were experiencing “even the mildest” of symptoms or feeling “generally unwell with no explanation”.

Meanwhile, Carmarthenshire County Council is calling on people to take responsibility for social distancing as a cluster of positive Covid-19 cases were confirmed in the county.

The cluster is centred around a presentation evening held on Saturday August 29 at Drefach Cricket and Football Club, organised in breach of coronavirus regulations.

To date, 12 people who are linked to the evening have tested positive for Covid-19 and all those who attended the event will be required to self-isolate for 14 days.

Councillor Philip Hughes, executive board Member for public protection, said the organising of the event showed “a complete disregard for the wider public”.

He added: “This virus has not gone away and unless we all take responsibility for our own actions we will be back in the dreadful situation where we will have to enforce the closure of some businesses and restrict people’s access to services.”

Cardiff Council said five popular bars in Cardiff centre were served with improvement notices for failing to comply with Covid-19 health and safety measures.

Cabinet member for environment councillor Michael Michael said: “It is the responsibility of businesses to ensure that social distancing is maintained and their premises can be used in a way that is safe for customers and staff and minimises the potential for Covid-19 to spread.”
