A second county in Wales will go into lockdown because of the rate of coronavirus cases.
The 240,000 people living in Rhondda Cynon Taf (RCT) 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.

Mr Gething previously warned a positive rate of 4% across Wales would trigger a national lockdown. The Wales average is 2.4%.
Figures on Wednesday showed RCT's case rate had almost caught up with Caerphilly, which had 83.4 per 100,000 people over the past seven days.
The lockdown restrictions have been imposed despite people in RCT having been asked to take extra precautions last week.
Contact tracing teams have been able to trace about half of the coronavirus cases in RCT "back to a series of clusters within the borough", Mr Gething told a press conference.
"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 Mr Gething 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 in Caerphilly, including:
For essentials - food and medicine For work, if you cannot work from home, or for education To obtain supplies for the essential upkeep, maintenance and functioning of the household To provide or receive emergency assistance To meet a legal obligation or to get access to public servicesMotorists will be able to drive through the county borough, providing they do not stop.
The rules can be enforced by a system of fixed penalty notices, which start at £60 to a maximum of £1,920, or unlimited fines in the courts.

"It's crazy. Last time it was so difficult. I don't understand how I can go into a pub but not a house.
"I'm doing flowers for a wedding this Saturday - what will they do? It's been so difficult with the weddings and funerals."
She said the town had been busy all day, but added: "What's it going to be like tomorrow?
"As for trade, people are going to be too afraid to go out again, especially older people. A few have said they had better stay in.
"It's really scary."
She said she will stay open "even if I put the shutters down and just take orders over the phone".
"I don't think anyone can be blamed. I think it's going to be around for a long time," she said.
Image caption Barber Sirwan Hussein says people are not wearing masks in the townBarber Sirwan Hussein said it was clear there was problems with people respecting covid rules.
"I think people don't care about social distancing," he said.
"I've been around everywhere, and not many people are wearing a mask.
"The UK is going to be locked down again - we'll all be in lockdown again."
He said he had a client who did not want to wear a mask, even though it is now the law indoors in Wales.
"He said if they want to fine me - fine me - I'll pay the fine, but I'm not going to wear a mask."
Rules allowing people to meet six people from their extended household in Wales will also not apply in RCT.
Mr Gething said residents will be able to meet outdoors "for the time being".
Rhondda Labour MP Chris Bryant said: "Now we need to stick to the rules and get the transmission rate down to protect the NHS and the most vulnerable."
Leanne Wood, Plaid Cymru Rhondda Member of the Senedd (MS), said it was "disappointing, but not a surprise".
"The sooner we get this under control, the sooner we can ease restrictions and the safer our loved ones will be," she added.
Pontypridd MP Alex Davies-Jones said: "I know the news of tighter coronavirus restrictions will be worrying for people across Ponty, but I am confident that this is the right approach in order to reduce the number of cases locally."

The difference in rules around pubs in RCT and Caerphilly prompted questions from the Welsh Conservative health spokesman Andrew RT Davies.
"The health minister must explain the rationale behind this and give guidance across Wales to prevent other lockdowns."
Mr Gething said pubs were a "factor in transmission" in RCT, but had not been in Caerphilly.
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.
Asked why he was not closing all pubs, Mr Gething said: "If there are no opportunities to drink in licenced premises we may see more people breaking the rules and drinking in each other's homes."
