Brighton and Hove will be placed into Tier 2 when it comes out of lockdown on Wednesday.
Other than a spike in mid-November, cases have been plummeting in the city over the last month, and are now among the lowest in the country.
However, the rate is still too high for it to be placed in the lowest Tier 1, and along with most of the rest of the country, it is going to be put into the middle tier, also known as high alert.
This means no socialising with anyone outside your household inside at all – and only up to six people at a time outside, including private gardens.
Pubs and bars must serve a substantial meal to remain open, with table service only. Orders must stop being taken at 10pm, ahead of an 11pm closure.
Other venues such as casinos, museums and bingo halls, must also close at 11, although theatres, cinemas and concert halls can stay open longer for performances starting before 10pm to finish.
Public attendance at inside and outside events, including sport, is capped at 2,000 or 50% of a venue’s capacity, whichever is lower.
Organised outdoor sport can continue, and indoor sport and exercise only if people can avoid mixing.
Brighton’s neighbouring areas East and West Sussex are also in Tier 2. Save for the Isle of Wight, Isles of Scilly and Cornwall, the rest of England is all in either Tier 2 or Tier 3.
Addressing the House of Commons today, Health secretary Matt Hancock said the decision as to which tier to place an area was based not just on rates, but also how cases are rising or falling and the current and projected pressure on the NHS.
The official rationale for the whole of Sussex being in Tier 2 is: “Case rates in Sussex are at 120 per 100,000 with a total positivity of 4.5%.
“However, the trend is increasing in several areas.
“NHS admissions have been fairly stable in the last month but there is increasing occupancy in units treating more serious cases.”
They will be reviewed again in a fortnight, and regularly after that.
He said: “We must all think of our own responsibility to keep the virus under control.
“We should see these restrictions not as a boundary to push and not as a limit to what the public health advice says we can safely in any area.
“But frankly, the less any one person passes on the disease, the faster we can get this disease under control together. And that is on all of us.”
Brighton Kemptown MP Lloyd Russell-Moyle tweeted: “We must not spend a moment longer in tier two than we have to.
“People in our city and towns have done so well in slowing the spread of the virus. We need to keep going.”
Brighton Pavilion MP Caroline Lucas said: “I know this will be difficult for so many, but I also know that community spirit in our city makes extraordinary things possible
“I’ll continue to do all I can to press Government to give greater support to struggling businesses, particularly in vital hospitality sector.”
