The UK government identified 77 cases of South African Covid variant as told by the health secretary.
The cases are under close observation, and contact tracing is under process.
International flights are considered the link to the spread and not community transmission.
Scientists say that the new variant could interfere with or harm the working of the current COVID vaccine.
What is the new variant?
The virus is known to mutate and undergo changes when it copies itself.
Many variants of this virus are circulating the world, and so is the South African variant called 501.V2.
It can be inconsequential but may also be infectious and harmful. The South African variant can now be found in 20 more countries.
The UK closed all travel corridor till 15 February because travelling is linked with the virus’s transmission. All arriving individuals are required to show negative COVID test results for entry.
Mr Matt Hancock, the health secretary, has advised being cautious at the border. They are also planning to quarantine visitors at the hotel as a safety measure.
Both Pfizer-BioNTech and Oxford-AstraZeneca vaccines require at least two doses. UK’s government has also vaccinated around three-quarters of all the 80-year-olds in the country and several care-homes. Mr Hancock said it is too early to predict the population’s proportion needs to be immunised before easing down the lockdown. The aim is to vaccinate 15 million patients by mid-February.
England’s chief deputy medical officer warned that people still transmit the virus even after vaccination. Therefore, everyone should abide by the regulations of lockdown.
On 14 January, the government confirmed 35 cases of the new south African variant. There was a probability of having 12 more cases.
However, the number of positive cases has fallen in the fourth day of row. It is the lowest figure since Christmas.
