A second county in Wales will go into lockdown because of the rate of coronavirus cases.
The 240,000 people living in Rhondda Cynon Taff will have restrictions imposed on their daily lives.
From 18:00 BST on Thursday, people will not be able to enter or leave the area without a reasonable excuse, such as travel for work or education.
All licensed pubs, bars and restaurants will have to shut at 23:00 every day, once the lockdown comes into effect.
Rules allowing people to meet others from their extended households indoors will be suspended in the county.
Health Minister Vaughan Gething said there had been a “rapid” rise in cases, with 82.1 infections per 100,000 people over the past seven days.
The latest equivalent figure across the whole of Wales is 21.4 per 100,000.
It is the second local lockdown in Wales, after Caerphilly was subject to restrictions last week.
The Rhondda Cynon Taff area is home to 240,000 people
Tuesday’s rate of positive tests in RCT was 4.3% – the highest in Wales – Mr Gething previously warned a positive rate of 4% across Wales would trigger a national lockdown.
Contact tracing teams had been able to trace about half of the coronavirus cases in RCT “back to a series of clusters within the borough”, he said.
“The rest are evidence of community transmission.”
One cluster is associated with a rugby club, and a pub in the lower Rhondda valley, another is connected to a club outing to the Doncaster races, which the minister said stopped off at a series of pubs on the way.
A review into the lockdown will be held in two weeks’ time.
Under the lockdown rules, no one will be able to leave or enter the county without a reasonable excuse.
The list of excuses to travel is the same as that seen in Caerphilly, including:
For essentials – food and medicine
For work, if you cannot work from home
To obtain supplies for the essential upkeep, maintenance and functioning of the household
To provide or receive emergency assistance
To meet a legal obligation, and to access or receive public services
Motorists will be able to drive through the county borough, providing they do not stop.
Testing centres have been open in the county borough
Rules allowing people to meet six people from their extended household will not apply in RCT.
Mr Gething said residents will be able to meet outdoors “for the time being”.
Pubs have been a “real factor” in the spread of the virus in RCT, the minister told a Welsh Government press conference where he made the announcement.
He said a series of bars and pubs have faced closures and improvement notices in the area.
A bar has been shut in Pontypridd after a series of breaches were captured on CCTV; a licensed premise was closed in Tonypandy and improvement notices for another bar in Pontypridd and a barbers in Tonypandy were also issued.
A further 50 licensed premises were visited by council officers over the weekend, Mr Gething said.
Rhondda Labour MP Chris Bryant said he had been “warning this would be necessary”.
My”Now we need to stick to the rules and get the transmission rate down to protect the NHS and the most vulnerable.”
