South Africa has been added to the red list as the United Kingdom imposes urgent travel restrictions to prevent the spread of the ‘worst ever’ Covid variant.


South Africa has been placed on the UK’s travel red list as health officials and ministers scramble to prevent the new Covid “super-variant” from entering the country, with one scientific expert describing it as the worst variant they have ever seen.

Experts in the United Kingdom believe the variant, B.1.1. The virus 529, which is rapidly spreading in South Africa, can reduce vaccine effectiveness by as much as 30%.

Although no cases have been identified in the UK, public health officials are contacting hundreds of people who have recently arrived from South Africa and asking them to take PCR tests.

Every day, more than 500 people arrive at UK airports from South Africa, and the race to get them to take a test is becoming increasingly urgent. The variant, which has 32 mutations, has been linked to decreased vaccine effectiveness, increased transmissibility, and increased infectivity, according to one senior health official.

In South Africa, there have been nearly 100 confirmed cases, but the country’s health minister believes there are many more due to an increase in cases in Gauteng province. A virologist at Imperial College London identified the vаriаnt on Tuesdаy, аnd i wаs the first to report it on Wednesdаy. In Botswаnа аnd Hong Kong, а smаll number of cаses hаve been reported.
