Countries including the US are starting to restrict air travel again. But it may be too late.
What is this new COVID variant in South Africa
South African scientists identified a new version of the coronavirus this week that they say is behind a recent spike in COVID-19 infections in Gauteng, the country’s most populous province. It’s unclear where the new variant actually arose, but it was first detected by scientists in South Africa and has now been seen in travelers to Belgium, Botswana, Hong Kong and Israel.
Health Minister Joe Phaahla said the variant was linked to an “exponential rise” of cases in the last few days, although experts are still trying to determine if the new variant is actually responsible

In a statement on Friday, the World Health Organization designated it as a “variant of concern,” naming it “Omicron” after a letter in the Greek alphabet.

Sharon Peacock, who has led genetic sequencing of COVID-19 in Britain at the University of Cambridge, said the data so far suggest the new variant has mutations “consistent with enhanced transmissibility,” but said that “the significance of many of the mutations is still not known.”
Lawrence Young, a virologist at the University of Warwick, described omicron as “the most heavily mutated version of the virus we have seen,” including potentially worrying changes never before seen all in the same virus.
