The findings show cases were rising as the country entered a four-week Lockdown on Nov 5 and that a sharp decrease followed as national restrictions were rolled out, according to the report published on Monday.
The study supports findings "that stronger measures would be needed in some areas to prevent the epidemic from growing and that local tiers needed to be toughened to keep the virus under control once national measures end this week," the report said, Bloomberg reported.
The results come as lockdown measures in England are due to end this week and Prime Minister Boris Johnson is facing opposition from some in his Conservative Party to his plan to replace the lockdown with a tiered system of restrictions for different areas. Hopes are that a vaccine can be administered quickly, beginning as soon as next month.
Clearance is possible as early as this week, according to a person familiar with the situation, who asked not to be identified because the process is confidential.
Findings of the Imperial College study showed 96 people in 10,000 were infected with the virus in the 11 days to Nov 24, down from 132 in the previous period. Infections fell by over 50 per cent in the northwest and north, two of the regions worst hit.
The so-called R rate fell to 0. 88 at the end of the period, below the key threshold of 1, when the spread of the virus accelerates and can lead to exponential growth in cases.
