LONDON, Eleven people in different regions of England have tested positive for the South African coronavirus variant without having any links to people who have travelled, prompting mass testing in the areas to contain the outbreak.
Britain, with the fifth-highest COVID-19 death toll in the world, has moved to tighten its borders out of concern that new variants of the virus will undermine its vaccination drive.
To contain the new outbreaks, residents in eight areas of the country will now be tested whether or not they are showing any symptoms, a process known as “surge testing”.
There are about 10,000 people in each area. Three are in London, two in the southeast, one in central England, one in the east and another in the northwest.
The government said on Monday the 11 cases were self-isolating and contact tracing would help to halt the spread.
Positive tests in the areas will be sequenced to identify any further spread of the South African variant, the government statement said.
Britain said on Jan 24 it had detected 77 cases of the South African variant and nine cases of the Brazilian variant, but said all were linked to travel.
In total, Public Health England said it had now identified 105 cases of the South African variant since Dec 22.
Scientists have said the South African variant appears to be more transmissible, but there is no evidence it causes more severe disease. But several laboratory studies have found that it reduces vaccine and antibody therapy efficacy.
Britain is battling a new wave of COVID-19 turbo-charged by the emergence in September of a more transmittable variant found in the southeast of England. The country’s official death toll passed 100,000 last week.
Britain is however making rapid progress in its vaccination programme, with nearly 9 million people receiving the first shot of either the Pfizer-BioNTech or the Oxford-AstraZeneca shot.
