The Africa Centres for Disease Control and Prevention said it strongly discouraged imposing travel bans on people coming from countries where the variant was reported. They might buy countries more time to speed up vaccination and introduce other measures, like masking and social distancing, but they are highly unlikely to prevent the entry of new variants, said Mark Woolhouse, a professor of infectious diseases at the University of Edinburgh.
Johns Hopkins University infectious disease specialist Dr. Jeffrey Barrett, director of COVID Genetics at the Wellcome Sanger Institute, thought that the early detection of the new variant could mean restrictions taken now would have a bigger impact than when the delta variant first emerged.
However, Barrett said harsh restrictions would be counter-productive and that the South African officials should not be punished for alerting the world to the new variant. Sharon Peacock, who has led the genetic sequencing in Britain at the University of Cambridge, said any decisions to restrict travel were political decisions, not scientific ones. She emphasized that there was still great uncertainty about the new variant, including whether it is actually more infectious or deadly.
Although some of the mutations detected appeared worrying, she said there is still no proof that the new variant is any more lethal or transmissible than previous versions.
