Restrictions increase in the world against omicron variant

Australian authorities were rushing Sunday to conduct more tests on passengers arriving in the country from southern Africa who tested positive for COVID-19 to determine if they had the omicron variant, as countries around the world tightened controls on the worrying variant.

Neighboring New Zealand announced that it was restricting travel from nine southern African countries due to the threat posed by the new variant, while Japan expanded its border controls to include more countries in the region. Thailand, a tourism-dependent country that had only recently begun to loosen restrictions on travelers from certain countries, announced a ban on its own visitors from eight African countries. Similar restrictions went into effect in Singapore, which barred entry to and transit from anyone with a recent travel history to seven South African countries.

The new restrictions in the Asia-Pacific region echo similar steps quickly taken by countries around the world to limit the spread of the omicron variant just days after it was first identified in South Africa. The urgent take on the approach reflected growing alarm over the emergence of a potentially more contagious variant nearly two years after the onset of a pandemic that has killed more than five million people, dramatically changed lives and battered economies around the world.

Although much remains to be understood about the new variant, experts fear that it is more resistant to the protection provided by vaccines and could mean that the pandemic lasts longer than anticipated.

Cases of the omicron variant have already been confirmed on several continents, with Germany, Italy, Belgium, Israel and Hong Kong reporting cases in recent days.

On Saturday, the UK tightened rules on the use of masks and testing of people arriving in the country, after detecting two cases of the new variant.

In the United States, Dr. Anthony Fauci, the government’s leading infectious disease expert, said he would not be surprised if the omicron variant beforehand is found on US soil.

“We have not yet detected it, but when a virus shows this degree of transmission … almost always it will end up spreading everywhere,” Fauci said in an interview with the NBC television network.

Italian news agency LaPresse noted that an Italian who traveled to Mozambique has tested positive for the omicron variant.

The traveler arrived in Rome on November 11 and returned home near Naples. He and five members of his family, including two school-age children, have since tested positive, according to LaPresse. Toso are isolated in the Neapolitan suburb of Caserta in good condition and with mild symptoms.

The variant was confirmed by the Sacco hospital in Milan, and the Italian National Institute of Health announced that the man had received both doses of the vaccine. The Italian Minister of Health has urged authorities in all regions of the country to increase the tracking of the virus.

In Germany, the Max von Pettenkofer Institute, a Munich-based microbiological center, reported that the omicron variant was confirmed in two travelers who arrived on a flight from South Africa on November 24. The director of the institute, Oliver Keppler, said that the genome sequence has not yet been completed, but it has “been shown without a doubt that it is this variant,” the German news agency dpa reported.

Several pharmaceutical companies, including AstraZeneca, Moderna, Novavax and Pfizer, said they are already planning to adapt their vaccines to the emergence of the omicron variant. Pfizer and its partner BioNTech announced that they expect to be able to adjust their vaccines in approximately 100 days.

The WHO identified the new variant with the name omicron, labeling it a worrisome version due to its high number of mutations and some early evidence that it is more infectious than other variants. That means that people who contracted COVID-19 and recovered could be subject to contracting the disease again. It could take weeks to know if current vaccines are less effective against omicron.

With so much uncertainty surrounding the omicron and due to the unlikely likelihood of scientists making much progress over a few weeks, countries around the world have been taking a security-first approach, knowing that previous outbreaks of the pandemic have been driven in partly because of lax border policies.
