Britain tightens COVID rules as omicron variant spreads

Among the new measures: Mandatory PCR tests for visitors and isolation for positive cases.

LONDON — The U.K. tightened up rules Saturday on mask-wearing and on testing of international arrivals after finding two cases of the new potentially more contagious omicron variant of the coronavirus.

Amid fears that the recently identified 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. Many countries have already imposed travel restrictions on flights from southern Africa in the four days since the omicron variant was first identified in South Africa.

In an attempt to slow the spread, British 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 will be asked to take a a mandatory PCR test for COVID-19 on the second day after their arrival and must 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 coronavirus vaccines has been asked to accelerate the vaccination program, potentially by expanding the numbers eligible for a booster jab or allowing older children to get a second dose of vaccine.

“From today we’re going to boost the booster campaign,” he said.

One of the two new cases was found in the southeastern English town of Brentwood, while the other is in the central city of Nottingham. The two cases are linked and involve travel from southern Africa. The two confirmed cases are self-isolating alongside their households while contact tracing and targeted testing takes place.

The British government also added four more countries — Angola, Malawi, Mozambique and Zambia — onto the country’s travel red list from Sunday. Six others — Botswana, Eswatini (formerly known as Swaziland), Lesotho, Namibia, South Africa and Zimbabwe — were added Friday. That means anyone permitted to arrive from those destinations will have to quarantine.

Many countries have slapped restrictions on various southern African countries over the past couple of days including Australia, Brazil, Canada, the European Union, Iran, Japan, Thailand and the United States, in response to warnings over the transmissability of the new variant — against the advice of the World Health Organization.

Despite the banning of flights, there are mounting concerns that the variant has already been widely seeded around the world. In addition to the U.K, cases have been reported in travelers in Belgium, Israel and Hong Kong. Germany also said it suspected a positive case and Dutch authorities were testing whether 61 people who arrived on two flights from South Africa with COVID-19 have the omicron variant .

Italian authorities in the southern region of Campania were also investigating whether a person who recently returned home from southern Africa and who has tested positive for the virus was infected with the omicron variant.

The global health body has named the new variant omicron, labeling it a variant of concern because of its high number of mutations and some early evidence that it carries a higher degree of infection than other variants. That means people who contracted COVID-19 and recovered could be subject to catching it again. It could take weeks to know if current vaccines are less effective against it.

With so much uncertainty about the omicron variant and scientists unlikely to flesh out their findings for a few weeks, countries around the world have been taking a safety-first approach, in the knowledge that previous outbreaks of the pandemic have been partly fueled by lax border policies.

Nearly two years on since the start of the pandemic that has claimed more than 5 million lives around the world, countries are on high alert.

The variant’s swift spread among young people in South Africa has alarmed health professionals even though there was no immediate indication whether the variant causes more severe disease.

A number of pharmaceutical firms, including AstraZeneca, Moderna, Novavax and Pfizer, said they have plans in place to adapt their vaccines in light of the emergence of omicron. Pfizer and its partner BioNTech said they expect to be able to tweak their vaccine in around 100 days.

Professor Andrew Pollard, the director of the Oxford Vaccine Group which developed the AstraZeneca vaccine, expressed cautious optimism that existing vaccines could be effective at preventing serious disease from the omicron variant.

He said most of the mutations appear to be in similar regions as those in other variants.

“At least from a speculative point of view we have some optimism that the vaccine should still work against a new variant for serious disease but really we need to wait several weeks to have that confirmed,” he told BBC radio.

He added that it is “extremely unlikely that a reboot of a pandemic in a vaccinated population like we saw last year is going to happen.”

Some experts said the variant’s emergence illustrated how rich countries’ hoarding of vaccines threatens to prolong the pandemic.

Fewer than 6 percent of people in Africa have been fully immunized against COVID-19, and millions of health workers and vulnerable populations have yet to receive a single dose. Those conditions can speed up spread of the virus, offering more opportunities for it to evolve into a dangerous variant.

“One of the key factors to emergence of variants may well be low vaccination rates in parts of the world, and the WHO warning that none of us is safe until all of us are safe and should be heeded,” said Peter Openshaw, a professor of experimental medicine at Imperial College London.
