The United Kingdom has banned flights to six southern African nations – South Africa, Botswana, Lesotho, Eswatini, Zimbabwe and Namibia - until Nov 28 over the spread of the B.1.1.529 strain of the coronavirus, the UK government said.
"From midday Friday (Nov 26) , South Africa, Botswana, Lesotho, Eswatini, Zimbabwe and Namibia will be added to the UK’s travel red list... Direct flights from the six countries will be banned from midday Friday until hotel quarantine is up and running from 4am Sunday (Nov 28)," Sputnik reported, quoting the government as saying in a statement.
Starting from Friday, non-UK and Irish citizens, who have visited the six African nations within the past 10 days, will be refused entry to the UK, while the UK and Irish citizens will be required to self-isolate for 10 days.
Earlier this week, scientists from the UK had warned of the appearance of a coronavirus strain, which contains 32 mutations, in Botswana. Many of the mutations indicate its high transmissibility and resistance to vaccines, the strain has more changes in the spike protein than all other COVID-19 variants. The South African National Institute of Infectious Diseases later also confirmed that the new strain had been found in South Africa, with 22 cases to date.
SA discovers new Covid-19 variant
Scientists in South Africa said yesterday they had detected a new Covid-19 variant with multiple mutations, blaming it for a surge in infection numbers.
”Unfortunately we have detected a new variant which is a reason for concern in South Africa,” virologist Tulio de Oliveira told a hastily-called news conference.
The variant, which goes by the scientific lineage number B.1.1.529, “has a very high number of mutations,” he said.”It’s unfortunately causing a resurgence of infections,” he said.
It has also been detected in Botswana and Hong Kong among travellers from South Africa, he said. Health Minister Joe Phaahla said the variant was of “serious concern” and behind an “exponential” increase in reported cases, making it “a major threat”.
Daily infections shot to more than 1 200 on Wednesday, up from around 100 earlier this month. Before the detection of the new variant, authorities had predicted a fourth wave to hit South Africa starting around the middle of December, buoyed by travel ahead of the festive season.
The government-run National Institute for Communicable Diseases (NICD) said 22 positive cases of the B.1.1.529 variant have been recorded in the country following genomic sequencing.
It said in a statement yesterday that detected cases and the percentage testing positive are “increasing quickly” in three of the country’s provinces including Gauteng, which includes Johannesburg and Pretoria.
A cluster outbreak was recently identified, concentrated at a higher education institute in the capital Pretoria, the NICD said.
Last year South Africa also detected the Beta variant of the virus, although until now its infection numbers have been driven by the Delta variant, which was originally detected in India.
The country has the highest pandemic numbers in Africa with around 2.95 million cases, of which 89,657 have been fatal.
Scientists said the new B.1.1.529 variant has at least 10 mutations, compared to two for Delta or three for Beta.
”What gives us some concerns (is) that this variant might have not just have enhanced transmissibility, so spread more efficiently, but might also be able to get around parts of the immune system and the protection we have in our immune system,” said researcher Richard Lessells.
So far the variant has been seen spreading especially among young people.But the coming days and weeks will be key to determine the severity of the variant, Lessells said.
Neutralising the variant is “complicated by the number of mutations this variant” contains, said one of the scientists Penny Moore. ”This variant contains many mutations that we are not familiar with,” she added.
