President Joe Biden will re-impose a Covid-19 travel ban on most non-US citizens who have been in Britain, Brazil, Ireland and much of Europe, a White House official said on January 24, as the new administration ramps up its pandemic response.

Biden on January 25 was also set to extend the ban to travellers who have recently been to South Africa amid warnings that new, more transmissible coronavirus variants are already establishing themselves in the US, the official said, confirming the country’s media reports.

The new president last week tightened mask wearing rules and ordered quarantine for people flying into the US, as he seeks to tackle the country’s worsening coronavirus crisis.

Biden has said the Covid-19 death toll would likely rise from 420,000 to half a million next month – and that drastic action was needed.

He said on January 21: “We’re in a national emergency. It’s time we treated it like one.”

In his last days in office, Donald Trump announced that a Covid-19 ban on travellers arriving from much of Europe and Brazil would be lifted – but the Biden administration immediately said it would reverse the order due to come into effect on January 26.

Trump had announced an initial ban on January 31, last year on non-US travellers entering from China to try to stop the spread of the coronavirus. The ban was extended to European countries on March 14 as the pandemic entered full force.

More than 25 million Covid-19 cases have been recorded in the US since the pandemic began, according to the Johns Hopkins University tally on January 24.

The milestone was reached only five days after the US, the world’s wealthiest and hardest-hit nation, recorded 400,000 deaths from the disease.

Biden has made fighting the coronavirus a priority and is pushing for Congress to approve a $1.9-trillion relief package that would include billions of dollars to boost vaccination rates.

The president, who was inaugurated on January 20, has said he wants 100 million people vaccinated within his first 100 days in office, and he has called for US citizens to “wear masks for 100 days”.
