Oldham, Pendle and Blackburn will face additional restrictions to stem the spread of Covid-19, the government has said.
From midnight Saturday, residents of these areas will not be allowed to socialize with people outside their homes.
Workplaces, daycares and businesses, including restaurants and pubs, will remain open.
Since July, the government has introduced additional restrictions after an increase in cases.
Elsewhere, Birmingham has been added to the government’s watch list as an ‘enhanced support area’, and Northampton has become a ‘response area’.
The current stricter rules in Wigan, Darwen and Rossendale must be dropped.
The additional measures in Oldham, Pendle and Blackburn will not prevent people from shopping, going to work or attending day care centers, including schools that open from September 1.
However, all social activities indoors and outdoors can only be shared with people you live with and who are in your immediate household.
Residents will be advised to avoid using public transportation except for essential travel, and the number of people who can attend weddings, civil partnerships and funerals will be limited to household members and immediate family, with no more than 20 people.
Local restaurants will also be encouraged to discontinue walk-in tours and only seat those who book in advance.
Health Secretary Matt Hancock said: “To avoid a second peak and keep Covid-19 under control, we need a robust and targeted response where we see a peak in cases.
“Our approach is to make the action we take as focused as possible, with as much local consensus as possible. ”
The peak in Northampton was “almost entirely due to an outbreak linked to the workforce at the Greencore factory,” a spokesperson for the Department of Health said.
Nearly 300 workers have tested positive and employees and their households are required to self-isolate at home for two weeks.
The number of cases has also “grown rapidly” in Birmingham, where the majority of new cases have been in people between the ages of 18 and 34, a government spokesperson said.
The city has 30.2 cases per 100,000, with a proportion of people testing positive up to 4.3%.
It has been categorized as an “improved area of support,” meaning it will be subject to further testing, more local contract monitoring and targeted community engagement.
