The World Health Organisation commended South African health officials for quickly reporting the discovery of a concerning new coronavirus variant, a decision that was swiftly met by travel bans from the UK, Germany and others.
Scientists on Thursday said they are studying a recently identified strain with a worrying number of mutations. Virologists in the country have detected almost 100 cases to date, with research underway as to how transmissible it may be and whether it will prove resistant to vaccines.
"This variant has been reported at a remarkable speed," Christian Lindmeier, a spokesman for the WHO, told reporters in Geneva on Friday. “"The WHO is grateful to the South African researchers, and it’s been outstanding how open and transparent they have been."
The praise will come as scant consolation to those forced to cancel trips to see families over the holiday season or South African business owners desperate for tourism to return to the country. The travel bans have drawn ire from local officials due to the early stage of the research into the variant, which may yet prove less lethal than feared.
Cases of the new variant have been identified in Hong Kong, Israel and Belgium, though the UK has yet to implement restrictions against those nations.
The WHO said countries should take a scientific approach to travel measures and cautioned against outright bans.
“Countries can do a lot to work on surveillance, on sequencing and collaborate with the affected countries,” Lindmeier said.
South Africa is one of just a few nations globally that has the expertise to quickly identify and track new virus variants. The first sequencing of the genome was completed on November 11, and the strain may have evolved during a chronic infection of an immuno-compromised person, possibly in an untreated HIV/AIDS patient. The virus can linger for longer in such a situation, potentially offering a bigger window for mutations.
A WHO expert panel has been meeting to discuss the variant, which has also been detected in Botswana, where it’s been found in people who were vaccinated against Covid-19. It will take a few weeks to study how the new variant may interact with vaccines.
Covid-19 new variant: Scores of Britons flood OR Tambo in desperate rush to get home
As scores of frustrated British citizens were desperate to depart South Africa amid news that the UK temporarily banned flights from the country, OR Tambo International Airport was abuzz with activity.
Pushing and pulling trolleys carrying their luggage, they went up and down, looking for the earliest flight to vacate South Africa.
The panic was caused by the sudden declaration by Britain to temporarily ban flights from six African countries, including South Africa, following news of a newly discovered Covid-19 variant identified as B.1.1.529.
Travellers would be required to quarantine upon arrival from South Africa, Botswana, Swaziland, Lesotho, Zimbabwe, and Namibia.
The six countries have been placed on Britain’s red list.
