The British government confirmed Saturday that people with COVID-19 won’t be legally required to self-isolate starting next week, as part of a plan for “living with COVID” that is also likely to see testing for the coronavirus scaled back.
Prime Minister Boris Johnson said ending all of the legal restrictions brought in to curb the spread of the virus will let people in the U.K. “protect ourselves without restricting our freedoms.”
But some of the government’s scientific advisers said it was a risky move that could bring a surge in infections and weaken the country’s defenses against more virulent future strains.
Johnson’s Conservative government lifted most virus restrictions in January, scrapping vaccine passports for venues and ending mask mandates in most settings apart from hospitals in England. Scotland, Wales and Northern Ireland also have opened up, although more slowly.
The announcement will please many Conservative Party lawmakers, who argue that the restrictions were inefficient and disproportionate. It could also shore up Johnson’s position among party lawmakers, who have been mulling an attempt to oust him over scandals including lockdown-breaching government parties during the pandemic.
But scientists stressed that much remains unknown about the virus, and future variants that may be more severe than the currently dominant omicron strain.
The New and Emerging Virus Threats Advisory Group, which advises the government, said last week that the idea viruses become progressively milder “is a common misconception.” It said the milder illness associated with omicron “is likely a chance event” and future variants could be more severe or evade current vaccines.
Epidemic modelers who advise the government also warned that “a sudden change, such as an end to testing and isolation, has the scope to lead to a return to rapid epidemic growth” if people throw caution to the wind.
Scientists also cautioned against scrapping free rapid coronavirus tests, which have been distributed by the millions during the pandemic. Health officials say the mass testing has played an important role in slowing the spread of the virus.
Scientists are also concerned the government might end the Infection Survey conducted by the Office for National Statistics, which is considered invaluable because it tests people whether or not they have symptoms.
“This is not the time to take risks,” said Matthew Taylor, chief executive of the NHS Confederation, an umbrella group for state-funded health authorities in Britain. “We need to operate in an evidence-based and incremental way. A combination of high vaccination rates in the U.K. and the milder omicron variant means easing restrictions didn’t lead to a surge in hospitalizations and deaths. Both are falling, though the U.K. still has Europe’s highest coronavirus toll after Russia, with more than 160,000 recorded deaths.
