Lockdown restrictions in parts of England, including Greater Manchester and Leicester, are to remain in place, the Government has said.
Restrictions on household gatherings in parts of the North West, West Yorkshire, East Lancashire and Leicester will continue, the Department of Health said.
The latest data does not show a decrease in the number of cases per 100,000 people in the area, and shows a continued rise in cases in Oldham and Pendle, while numbers remain high in Blackburn with Darwen, the department said.
The measures will be reviewed again next week.
Health minister Edward Argar said: “I’d like to thank everyone in Greater Manchester, West Yorkshire, East Lancashire and Leicester for their continued patience in following these vital rules put in place to tackle the spread of the disease – I know it hasn’t been easy.
“We will review the measures again next week as part of our ongoing surveillance and monitoring of the latest data.
“It is essential we all remain vigilant and I urge everyone in these areas to continue to follow the rules - wash your hands regularly, follow social distancing, get yourself a free test as soon as you get any symptoms, and isolate if NHS Test and Trace tells you to."
Regarding Leicester, a government spokesman said: “The latest evidence does not show a decrease in the number of cases per 100,000 people in the area, and the Health Secretary, in collaboration with local leaders, has agreed that the rules must remain in place at present.
“This will help protect local residents, and allow more time for the changes to have an effect, cutting transmission among households."
Local leaders are now setting up an enhanced incident team to try to bring infection rates under control, with support offered from the Government, and progress will be assessed throughout the weekend.
The announcement means people still cannot mix with other households, apart from those in their support bubble, within private homes or gardens, and leisure facilities and beauty salons will remain closed.
People will still be able to meet others in group of up to six individuals, or two households, in outdoor public places.
