Read more about ‘Maximise defences’: World on alert as Covid strain found in more countries on Business Standard. Despite the banning of flights from southern African countries, there are mounting concerns that the variant has already been widely seeded around the world.
The new potentially more contagious omicron variant of the popped up in more European countries on Saturday, just days after being identified in South Africa, leaving governments around the world scrambling to stop the spread. 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. In the U.S., Dr. Anthony Fauci, the government’s top infectious diseases expert, said he would not be surprised if the omicron variant was already in the United States, too.

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. He also said mask-wearing in shops and on public transport will be required and said the independent group of scientists that advises the British government on the rollout of vaccines has been asked to accelerate the vaccination program.
