Only 10 cases in three countries have been confirmed by genomic sequencing, but the variant has sparked serious concern among some researchers because a number of the mutations may help the virus evade immunity.
The variant was first spotted in Botswana, where three cases have now been sequenced. Six more have been confirmed in South Africa, and one in Hong Kong in a traveller returning from South Africa.
Dr Meera Chand, the Covid-19 incident director at the UK Health Security Agency, said that in partnership with scientific bodies around the globe, the agency was constantly monitoring the status of Sars-CoV-2 variants as they emerge and develop worldwide.
The first cases of the variant were collected in Botswana on 11 November, and the earliest in South Africa was recorded three days later. The case found in Hong Kong was a 36-year-old man who had a negative PCR test before flying from Hong Kong to South Africa, where he stayed from 22 October to 11 November. He tested negative on his return to Hong Kong, but tested positive on 13 November while in quarantine.
England no longer has a red list to impose restrictions on travellers arriving from abroad. People who are not fully vaccinated must test negative before flying and arrange two PCR tests on arrival. Those who are fully vaccinated need to have a Covid test within two days of landing.
Scientists will be watching the new variant for any sign that it is gaining momentum and spreading more widely. Some virologists in South Africa are already concerned, particularly given the recent rise in cases in Gauteng, an urban area containing Pretoria and Johannesburg, where B.1.1.529 cases have been detected.
A Delta Air Lines flight bound for New York City from Las Vegas made an emergency landing shortly after takeoff on October 29, 2024, due to fumes in the cockpit. Flight DL2133, originating from Harry Reid International Airport (LAS) in Las Vegas and destined for LaGuardia Airport (LGA) in New York, reported an issue within minutes of departure, leading the crew to declare an emergency and return to the Las Vegas airport for a safe landing.
