North East Lincolnshire now has the lowest case rate of any level 3 local authority region, and is now the eighth lowest in England.
This will raise hopes that the region could be downgraded during the government’s next review on Wednesday, December 30.
However, new outbreaks of Covid in other parts of the country could make this difficult.

North East Lincolnshire has a case rate of 110 per 100,000 people, according to data from Public Health England for the seven days to December 23.
North Lincolnshire is slightly higher at 185 per 100,000 population.
East Lindsey (also level 3) is the eleventh lowest area in the country, with a case rate of 121.4 per 100,000.
Some areas that are at level 2 have climbed more than three times that rate.
Despite local success in removing the virus, there is no guarantee that North Lincolnshire will be moved to level 2.
Public health officials have previously said areas are unlikely to be downgraded when reviewing levels this week as the country faces outbreaks caused by the new mutant strain.
Other areas are also facing the prospect of level 4 restrictions.
