COVID variant ‘worst one we’ve seen so far’ – flights banned from six countries put on red list

Britain is bringing in travel restrictions for six African countries due to a new COVID variant that UK experts have called the “worst one we’ve seen so far”.

Health Secretary Sajid Javid tweeted: “UKHSA (UK Health Security Agency) is investigating a new variant. More data is needed but we’re taking precautions now.

“Six African countries will be added to the red list, flights will be temporarily banned, and UK travellers must quarantine.”

Flights from South Africa, Namibia, Lesotho, Botswana, Eswatini and Zimbabwe will be suspended from 12pm on Friday.

Mr Javid said the new B.1.1.529 variant identified in South Africa “may be more transmissible” than the Delta strain – and warned “the vaccines that we currently have may be less effective”.

The UKHSA says it is the “worst one we’ve seen so far” and has a spike protein that is “dramatically” different to the original COVID strain – as well as double the amount of mutations seen in the Delta variant.

These mutations are likely to evade the immune response generated by prior infection and vaccination, they say.

Tom Peacock, a virologist at Imperial College London, described the mutations as “really awful” but said cases were currently “super low”.

Spike proteins are what viruses use to get into human cells, and some vaccines work by training the body to recognise the spikes and neutralise them.

Mutations on the spike could therefore potentially prove problematic.

But with only a handful of recorded cases – three in Botswana, around 53 in South Africa and one in Hong Kong from someone who had travelled from South Africa – scientists are hopeful it can be contained.

Francois Balloux, professor of computational systems biology at University College London, said it should be closely monitored but “there is no reason to get overly concerned, unless it starts going up in frequency in the near future”.

World Health Organisation experts are meeting on Friday to assess the variant, which on Wednesday was classed a variant under monitoring.

If it is upgraded to a variant of concern, it could be given a name from the Greek alphabet.

However, it could also be classed as a less serious variant of interest, indicating it has characteristics that may affect factors such as transmissibility and disease severity.
