MORE OMICRON CASES EMERGE AS WORLD RUSHES TO LEARN MORE
THE HAGUE, Netherlands — Cases of the Omicron variant of the coronavirus popped up in countries on opposite sides of the world Sunday and many governments rushed to close their borders even as scientists cautioned that it’s not clear if the new variant is more alarming than other versions of the virus.
The variant was identified days ago by researchers in South Africa, and much is still not known about it, including whether it is more contagious, more likely to cause serious illness or more able to evade the protection of vaccines. But many countries rushed to act, reflecting anxiety about anything that could prolong the pandemic that has killed more than 5 million people.
The U.S. plans to ban travel from South Africa and seven other southern African countries starting Monday. “It’s going to give us a period of time to enhance our preparedness,” the United States’ top infectious diseases expert, Dr. Anthony Fauci, said of the ban on ABC’s “This Week.”
Israel decided to bar entry to foreigners, and Morocco said it would suspend all incoming flights for two weeks starting Monday — among the most drastic of a growing raft of travel curbs being imposed by nations around the world as they scrambled to slow the variant’s spread. Scientists in several places — from Hong Kong to Europe — have confirmed its presence. The Netherlands reported 13 Omicron cases on Sunday, and both Canada and Australia each found two.
Noting that the variant has already been detected in many countries and that closing borders often has limited effect, the World Health Organization called for frontiers to remain open.
Dr. Francis Collins, director of the National Institutes of Health in the United States, meanwhile, emphasized that there is no data yet that suggests the new variant causes more serious illness than previous COVID-19 variants.
“I do think it’s more contagious when you look at how rapidly it spread through multiple districts in South Africa. It has the earmarks therefore of being particularly likely to spread from one person to another. … What we don’t know is whether it can compete with Delta,” Collins said on CNN’s “State of the Union.”
Collins echoed several experts in saying
the news should make everyone redouble their efforts to use the tools the world already has, including vaccinations, booster shots and measures such as mask-wearing.
“I know, America, you’re really tired about hearing those things, but the virus is not tired of us,” Collins said.
The Dutch public health authority confirmed that 13 people who arrived from South Africa on Friday have so far tested positive for Omicron.
Canada’s health minister says the country’s first two cases of Omicron were found in Ontario after two individuals who had recently traveled from Nigeria tested positive.
