Nations Concerned About New COVID-19 Version 'Omicron' from Africa

A new variant1 of COVID-19 found in Africa has international health organizations and national leaders again concerned about virus restrictions2.

A group of World Health Organization experts has called the variant "omicron," a letter in the Greek alphabet like "delta3."

Belgium and Israel said travelers who came from Africa recently tested positive for the variant.

It is not clear whether the new version of the virus causes more severe health problems. But nations are trying to prevent its spread.

The health minister in Belgium called the variant "suspicious." Frank Vandenbroucke said: "We don't know if it's a very dangerous variant."

In The Netherlands, an airplane with passengers from Cape4 Town, South Africa was held on the runway for four hours for extra testing.

One passenger called the situation "ridiculous."

Jens Spahn is the German Health Minister. He said problems from a new variant are "the last thing we need."

President of the European Commission Ursula von der Leyen said Europe needs to be careful until more is known about the variant. She asked travelers from southern Africa to "respect strict quarantine rules." She asked for care to make sure the variant does not spread around the world.

The traveler who tested positive in Belgium spent over one week in the country before getting a test because of mild signs of infection. In Israel, a traveler and two other people were quarantined. All the individuals had been vaccinated5.

Health experts say the spread of the variant in Africa shows the problem with unequal availability of vaccines7. Fewer than six percent of people in Africa have been fully8 vaccinated against COVID-19.

Michael Head is a global health researcher at the University of Southampton in Great Britain. He said the new variant coming in Africa results from wealthier nations buying more vaccine6 than they need. He said large countries should do more to send vaccines to smaller countries.

Investors9 around the world showed their concern about the new variant. Measures of stock prices dropped on Friday in Asia, Europe and the U.S.

Dr. Michael Ryan is the head of emergencies at the World Health Organization. He warned against "knee-jerk responses" to the variant. A knee-jerk reaction is one that is done without thought or reason.

However, Britain banned travel from southern Africa on Friday.

The United States announced restrictions on visitors from South Africa, Botswana, Zimbabwe, Namibia, Lesotho, Eswatini, Mozambique and Malawi. Canada and the European Union also have placed restrictions on visitors from southern African countries. And Japan announced 10-day quarantines for citizens coming from countries in southern Africa.
