The figures released on Thursday are more than double the 520 registered by the UK Institute of Public Health (PHE) on 5 May.
The return of some economic and social restrictions in some areas of the country is not ruled out.
The Department of Health and Social Assistance (DHSC) considers that “there is still no strong evidence that the variant has a greater impact on the severity of the disease or that it is resistant to the vaccine”.
“We are monitoring the situation very carefully and we will not hesitate to take further action if necessary,” Health Secretary Matt Hancoock told the BBC.
Prime Minister Boris Johnson did not rule out, on Thursday, the reintroduction of regional measures. “It is a variant that causes great concern, we are concerned”.
However, Boris Johnson added that there is no evidence to indicate that the de-escalation scheduled for May 17 cannot continue.
Thursday, the UK reported 11 deaths from Covid-19 and 2284 new infections.
Between May 7 and 13, the daily average was ten deaths and 2,297 cases, which corresponds to a decrease in the number of deaths of 16 percent, but a 12.4 percent increase in the number of infections over the seven days. previous ones.
Thursday was the third day on which the weekly trend is increasing, which coincides with the number of infections with the Indian variant.
Nearly 36 million people have already received at least one dose of the Covid-19 vaccine. The PHE claims that vaccines saved 11,700 lives and prevented 33,000 people from becoming seriously ill in England.
Contact testing and tracking are taking place at specific locations to prevent outbreaks from spreading.
According to DHSC, additional measures are being taken where outbreaks are detected, including sequencing the genome of cases to monitor variants, increasing community involvement and encouraging the population eligible for the vaccine.
Nick Loman, a PHE consultant, said the vaccines are working “very well”. “I personally think that there is a role in the use of vaccines to reach particularly the most affected areas”.
The cases of the Indian variant were detected in London, Bolton, Tyneside and Nottingham.
In Bolton, mobile testing units were installed and 22,000 residents were offered door-to-door PCR testing. PCR tests are the most accurate way to verify the existence of Covid-19.
A vaccination bus was also installed, with 100 nurses and public health advisers, to increase the vaccination process.
In Blackburn, Darwen and Lancashire will open more vaccination centers next week.
The tests were also reinforced in Sefton, Merseyside, after cases of the Indian variant have been confirmed in the Formby area, where anyone over the age of 16 is asked to live, work or study in the area to perform a PCR test. .
