UK urgently brings travel restrictions to stop COVID-19 spreading

Published on : Friday, November 26, 2021


Britain is bringing in travel restrictions for six African countries due to a new COVID-19 variant.

Health Secretary Sajid Javid tweeted that UKHSA (UK Health Security Agency) is investigating a new variant. More data is needed but they are taking precautions now.

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

The flights from South Africa, Namibia, Lesotho, Botswana, Eswatini and Zimbabwe will be suspended from 12pm today until 4am on Sunday.

From Sunday onwards, new arrivals in the UK will be required to quarantine in hotels.

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. The variant also has 30 mutations – twice as many as the Delta variant – and these mutations are likely to evade the immune response generated by prior infection and vaccination.

But the good news is that B.1.1.529 can be detected with a normal PCR test. Scotland and Northern Ireland have said they are also introducing the new rules.

No cases of this variant have been reported so far in the UK, and anyone who has travelled from one of these countries in the past 10 days is now being invited to come forward for a test.

About 500 to 700 people are travelling to the UK from South Africa each day at the moment, but it is expected this figure could increase in the run-up to Christmas.

According to aviation analyst Alex Macheras, Virgin Atlantic had reported taking more than 32,000 bookings for South Africa in October alone – and most of them for the rest of 2021. Tom Peacock, a virologist at Imperial College London, described the mutations as “really awful” but said cases were currently “super low”.

The 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. The 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”.

In South Africa, health minister Joe Phaahla has said that there has been more of an exponential rise” in cases “over the last four or five days”.

Until recently, the country had been reporting about 200 confirmed cases per day – but this has rapidly increased over the past week, hitting 2,465 on Thursday.

The scientists from seven South African universities are now studying the variant, and are trying to determine how many of these new cases are linked to it.
