Britain on Thursday said it was concerned by a newly identified coronavirus variant spreading in South Africa that might make vaccines less effective and imperil efforts to fight the pandemic.

Iran PressEurope: The UK will temporarily ban flights from South Africa and five neighboring countries over worries about a new, dramatically different Covid-19 variant recently identified in the region. 

The travel restrictions go into effect at noon Friday and are a precautionary measure to keep the spread of the new variant in check, Health Secretary Sajid Javid said. The six African countries will be placed on the UK’s red list as of Sunday, requiring travelers to quarantine in hotels upon arrival.

More than 10 million coronavirus cases have been recorded in Britain since the start of the COVID-19 pandemic, according to official figures released Thursday. 

The UK currently has the highest number of people infected with the Crohn's virus among European countries.

Scientists are still trying to determine whether the new variant, called B.1.1529, is more transmissible or more lethal than previous ones. What’s clear is that it has the most mutations of any strain yet identified. That’s raised concerns inside South Africa and internationally, with authorities fearing a wave of cases that could increase pressure on already strained health-care systems. 219
