Residents in Oldham are facing stricter coronavirus measures following a spike in cases.
Health officials fear the increase could lead to a local lockdown like the one seen in Leicester, so have introduced the new restrictions immediately.
People in the Greater Manchester borough will not be allowed to have social visitors to their home and will have to keep two metres apart when seeing friends and family outside.
Care homes will not follow the recent lifting of restrictions on visitors, and those who are "shielding" will have to continue to stay at home for another two weeks from Friday.
The new guidance, which will last two weeks, follows an increase in cases over the last week.

In the week to 25 July, Oldham recorded 119 cases. In the previous week it saw just 26 positive cases.
This means there is a current rate of 50.2 positive tests per 100,000 versus 10.2 per 100,000 the week before.

Residents are being urged to book a coronavirus test if they show any symptoms.
The current guidance in England also means that people should wear face masks in shops or on public transport, and should not take part in any gathering of more than 30 people.

When meeting outside, people should meet in groups of no more than six from different households.
Gatherings of more than six people can only take place with a maximum of two households or support bubbles.
Oldham Council said many of the recent cases in the borough are multiple people testing positive within a household, pointing to a spread among households with large families.
