Beginning Monday, the United States will restrict travel from South Africa and several other nations following news of a new, potentially more transmittable COVID-19 variant dubbed Omicron.
The restrictions apply to South Africa, Botswana, Zimbabwe, Namibia, Lesotho, Eswatini, Mozambique and Malawi. The ban on travel will not apply to American citizens or lawful permanent residents although those individuals must still test negative prior to traveling.
The new variant, first detected in South Africa, has already been detected in Europe.
The Associated Press reported that the U.K. on Saturday tightened its rules on mask-wearing and on testing of international arrivals after finding two cases. New cases were confirmed Saturday in Germany and Italy, with Belgium, Israel and Hong Kong also reporting that the variant has been found in travelers.
Dr. Anthony Fauci, America’s top infectious diseases expert, said he would not be surprised if the omicron variant was already in the United States, too. “We have not detected it yet, but when you have a virus that is showing this degree of transmissibility … it almost invariably is ultimately going to go essentially all over,” Fauci said on NBC television.
Because of fears that the new variant has the potential to be more resistant to the protection offered by vaccines, there are growing concerns around the world that the pandemic and associated lockdown restrictions will persist for far longer than hoped.
Nearly two years since the start of the pandemic that has claimed more than 5 million lives around the world, countries are on high alert. Many have already imposed travel restrictions on flights from southern Africa as they seek to buy time to assess whether the omicron variant is more transmissible than the current dominant delta variant.
In Britain, Prime Minister Boris Johnson said it was necessary to take “targeted and precautionary measures” after two people tested positive for the new variant in England.
“Right now this is the responsible course of action to slow down the seeding and the spread of this new variant and to maximize our defenses,” he told a news conference.
Among the measures announced, Johnson said anyone arriving in England must take a PCR test for COVID-19 on the second day after their arrival and self-isolate until they provide a negative test. And if someone tests positive for the omicron variant, then he said their close contacts will have to self-isolate for 10 days regardless of their vaccination status — currently close contacts are exempt from quarantine rules if they are fully vaccinated.
Britain’s Department of Health said the two cases found in the U.K. were linked and involved travel from southern Africa. One of the two new cases was in the southeastern English town of Brentwood, while the other was in the central city of Nottingham. The two confirmed cases are self-isolating with their households while contact tracing and targeted testing takes place.
The British government also added four more countries — Angola, Malawi, Mozambique and Zambia — onto the country’s travel red list from Sunday. Six others — Botswana, Eswatini (formerly Swaziland), Lesotho, Namibia, South Africa and Zimbabwe — were added Friday. That means anyone permitted to arrive from those destinations will have to quarantine.
Many countries have slapped restrictions on various southern African countries over the past couple of days, including Jamaica, Australia, Brazil, Canada, the European Union, Iran, Japan and Thailand, in response to warnings over the transmissibility of the new variant. This goes against the advice of the World Health Organization, which has warned against any overreaction before the variant was thoroughly studied.
Despite the banning of flights, there are mounting concerns that the variant has already been widely seeded around the world.
Italy and Germany were the latest to report confirmed cases of the omicron variant.
