Will flight restrictions help as new virus variant emerges?

A coronavirus variant recently identified in South Africa is leading to a new round of travel restrictions just as many had finally begun to ease
A new coronavirus variant identified in South Africa is leading to a new round of travel restrictions just as many had finally begun to ease.
The risks of the variant, called omicron, are largely unknown. But the World Health Organization has called it a “variant of concern” and governments around the world are not waiting for scientists to better understand the variant to impose flight bans and other travel restrictions.
The U.S. said Friday it will ban travel from South Africa and seven other African nations by non-US citizens beginning Monday. European Union nations agreed earlier in the day to impose a ban on travel from southern Africa to counter the variant's spread. The U.K., Canada and other countries have imposed similar restrictions.
The moves have renewed a debate over whether flight bans and other travel restrictions work to prevent the spread of new variants. Some say at best the restrictions can buy time for new public health measures to be put in place. At worst, they do little to stop the spread and give a false sense of security.
