I live in the UK and this is the first I’ve heard of this. We’re being shut down as well.
As Europe Shuts Down, Britain Takes a Different, and Contentious, Approach
Prime Minister Boris Johnson of Britain once said his political hero was the mayor in the film “Jaws,” praising him for defying mass hysteria to keep the beaches open after a constituent is eaten by a shark.
As the coronavirus now stampedes across Britain and much of the world, Mr. Johnson is heeding the same principle, spurning the mass closures that have become commonplace across Europe and gambling his political future on a more restrained approach.
While countries across Europe have shut schools, sporting events and even restaurants and bars, Mr. Johnson has largely kept Britain open, opting for more targeted measures like asking people with respiratory symptoms to stay home. In effect, his government has said that mass closures will not halt the outbreak, and that exposing a large segment of the population will help build immunity and limit future infections.
That strategy has startled some epidemiologists, drawn criticism from a former health secretary and political ally, and prompted angry demands that Mr. Johnson’s government reveal more of its reasoning.
Cases of the coronavirus in Britain, held low for weeks as officials tracked down the contacts of known patients, have now surged, rising to nearly 800 on Friday from fewer than 600 a day before. With testing limited to hospital patients, Mr. Johnson said on Thursday that the true number of people infected may be as many as 10,000.
“There’s no other country in the world managing the epidemic in the same way,” Francois Balloux, an infectious disease epidemiologist at University College London, said of Britain’s approach. But, he said, “It’s not an insane decision. And it might actually pay off.”
The government is leaning heavily on skepticism in some scientific circles about the effectiveness of mass closures. Some epidemiologists fear that closing schools only pulls front-line doctors and nurses away from their work, and believe that large events are less dangerous for spreading the virus than more intimate gatherings at bars or at people’s homes.
It has also said that the measures it has taken, like asking people with persistent coughs and high temperatures to stay home for a week, will reduce the spread of the virus considerably.
But British advisers are also leaning on a more contentious theory: that exposing a large proportion of the population to the coronavirus could help people develop immunity, and put Britain in a better position to defend itself against the virus roaring back next winter.
Sir Patrick Vallance, England’s chief scientific adviser, said the government was looking “to build up some kind of herd immunity so more people are immune to this disease and we reduce the transmission.”
Herd immunity, a term usually used to refer to the way mass vaccinations can stop the spread of disease and protect people who are not immune, is not seen by many scientists as a tool to be used against the coronavirus. Mr. Vallance has said that it would require roughly 60 percent of Britons to become infected, creating enough immunity in the population that a second surge in cases next winter would be less severe.
But experts said that was an unusual and untested approach, and that it would be impossible to keep older and more vulnerable people from becoming infected too, putting them at a significant risk. They cautioned that the science was unsettled on how quickly people develop immunity to the coronavirus, and for how long. And experts urged the government to show more of the evidence behind its thinking.
“Herd immunity means 70 percent of people or so have been infected,” said Martin Hibberd, a professor of infectious diseases at the London School of Hygiene and Tropical Medicine. “In my mind, that’s not a desirable aim. That’s a kind of consequence of the strategy.”
