Three more counties are to be placed under local lockdown on Monday, the Welsh government said.
Neath Port Talbot, Torfaen and Vale of Glamorgan will have stricter restrictions on Covid-19 from 6:00 p.m. BST on Monday.
This means half of Wales’ 22 local authority areas will be under local lockdown, as the rules take effect in Cardiff and Swansea later on Sunday.
Nearly two million people in Wales – two-thirds of the population – will be under local lockdown.
Vale of Glamorgan Council Chief Neil Moore said it had not been an easy decision, but pointed out the infection rate was as high as 34.4 people per 100,000 in the county borough.

“We made a decision today for early and preventive action,” he said.
“One of the main reasons for this is that the sooner we stop the increase in transmission, the sooner the restrictions can be lifted.
“Now we all need to work together to make this possible. ”
Blaenau Gwent at 202 per 100,000 and Merthyr Tydfil with 169 per 100,000 currently have the highest infection rates.
Neath Port Talbot Council Chief Rob Jones said: “These restrictions are being imposed to protect public health, to protect you and your loved ones, and to prevent people from dying.
“Rates are much higher in the local authority areas that border our county borough, but we are now seeing an increase in rates here in Neath Port Talbot.
“We need everyone’s help at Neath Port Talbot to prevent the increasing spread of the coronavirus and bring down infection rates. ”
Mr Jones also urged people not to panic buying, adding: “There is no need to worry about falling stocks.”
Local Welsh foreclosure rules mean extended households must cease and people are not allowed to leave or enter council boundaries without a reasonable excuse.
People are allowed to travel outside the area for a limited number of reasons.
These include going to work if they are unable to work from home, attend school, provide care, or purchase food or medical supplies.
Blaenau Gwent, Bridgend, Caerphilly, Merthyr Tydfil, Newport and Rhondda Cynon Taf are all on lockdown, as is Llanelli in Carmarthenshire, which on Saturday became the first town to have restrictions imposed that do not apply to the whole County.
Cardiff and Swansea both lock down at 6 p.m. BST on Sunday.
As of Monday evening, nearly 1.9 million of Wales’ 3.1 million people will be subject to local coronavirus rules.
Prime Minister Mark Drakeford said: ‘We are now taking further action and placing three other areas under local restrictions in South Wales – Neath Port Talbot, Torfaen and the Vale of Glamorgan – as we see an increase in rates in these three areas. These areas also share borders with local communities where the rates are much higher.
“Introducing restrictions in any part of Wales is always an incredibly difficult decision for us. But we are acting to protect people’s health and to try to break the chain of transmission and prevent the situation from getting worse.
“This is not a regional lockdown – it is a series of local restrictions in each local authority area to address a specific increase in cases in each area, which have separate chains of transmission. and unique. “
Welsh Conservative health spokesman Andrew RT Davies said: ‘The Prime Minister may not want this described as a’ regional lockdown ‘but with two million people in the southern corridor of Wales now in some form of restrictions, unfortunately that is what it is. ”
He called for a more targeted approach – “local, not regional” – and said urgent financial support was needed for affected businesses.
