We’re the accidental Sweden, raising fears Covid-19 will get worse – STAT
July 16, 2020
With the Covid-19 pandemic rampaging across the U.S. in April and 20 million people filing for unemployment in that month alone, libertarians thought there was a better way. The Heritage Foundation praised Sweden for preserving economic freedom. The Cato Institute said Swedens response to Covid-19 may prove to be superior from a public health perspective. In early May, Sen. Rand Paul (R-Ky.) said at a committee hearing that the U.S. ought to look at the Swedish approach.
The Swedish approach was to largely allow businesses to remain open. And at first, it seemed to work, with a death count nowhere near what it was in countries such as Italy, Spain, and the U.K. But even as Sweden was being hailed as a model, its cases were steadily rising, and its death rate now exceeds that of the U.S. Sweden also did not seem to stave off the economic damage it was aiming to avoid.
Swedens Covid-19 strategy, adopted in March, emerged from the countrys top epidemiologist and other leaders evaluation of what little science about transmission there was at the time, factoring in economic considerations, and making a considered albeit controversial decision to stop well short of the full shutdown that other countries in western Europe (and many U.S. states) adopted.

In early summer, parts of the U.S. began following a very similar path but one it has stumbled onto, not chosen based on science. Now, the next few weeks will show the consequences of being the accidental Sweden.
In some ways you could say were doing Sweden, but unintentionally and, crucially, without the guardrails that kept that countrys case count from exploding, said physician David Rubin, director of PolicyLab at Childrens Hospital of Philadelphia (CHOP), whose Covid-19 model shows the epidemic resurging through early August almost everywhere in the U.S. but New England.

In addition to places like Arizona, Texas, and Florida that have been hammered since June, the latest run of the CHOP model identifies Las Vegas, Los Angeles, northern California, Kansas City, Mo., Tulsa, Okla., Greenville, S.C., and Atlanta as poised for widespread transmission. And there are early signs that the virus is moving up busy travel routes, spreading north to Baltimore, Philadelphia, and all of Ohios major cities.
By doing Sweden, Rubin and other experts mean Americans pullback from social distancing that dates from May, when states began lifting stay-at-home orders and other policies aimed at reducing viral transmission. The effect has had many of the failed aspects of Swedens approach, but with none of the steps that kept that country from being a total disaster.
Sweden never imposed a total shutdown of nonessential businesses. It closed universities and banned gatherings of more than 50 people, including sports events, and discouraged domestic travel. But most bars, restaurants, schools, salons, and stores were allowed to remain open, with largely voluntary social distancing. If Spain and Italy got hit by an early Covid-19 tsunami, said Peter Kasson of the University of Virginia School of Medicine and Swedens Uppsala University, Sweden said, lets go swimming.
Many of its citizens, however, didnt jump into the deep end. For one thing, a lot of Swedes went well beyond the official recommendations for social distancing, individually taking the kinds of actions that in other countries were mandated, said Kasson, co-author of a recent study of Swedens strategy. A lot of people self-isolated at home, and companies promoted working from home even though it wasnt mandated. That shows that individual decisions that reduce [viral transmission] can have a substantial effect on national outcomes.
Among those individual decisions: 58% of Swedes didnt meet friends, and 74% stayed home during their spare time, researchers reported in May.
Sweden also issued its distancing recommendations early. Imposing less restrictive policies right away can be more effective at slowing transmission and preventing cases than stricter measures later in an outbreak.
In contrast, if Swedes had done everything they were allowed to do (especially since face coverings were never required nationally), such as shop and socialize at the same levels they had pre-pandemic, it would likely have led to runaway infection, Kasson said. But Sweden is a place with a very strong embrace of government authority. When that authority said keep gatherings small, Swedes took individual actions that went beyond the mandated measures, he said.
Sweden is 18th in the world in Covid-19 cases per million people, with 7,524 as of Tuesday. Thats better than the U.S. (10,626), but much worse than European countries that imposed shutdowns. Sweden is seventh in deaths per million people (with 549; the U.S. is ninth, with 419), though the U.K., Spain, and Italy are worse, possibly because of older populations, denser cities, and more imported cases early on. But a death rate nearly 12 times Norways is hardly reason for celebration. (In fairness, however, there is evidence that one reason for Swedens high death toll is that when elderly people contracted Covid-19, they did not receive aggressive treatment, Kasson found; if they had, about one-third might have survived.)
Because factors that kept Swedens numbers from being even more dire are largely absent in much of the U.S., there is growing concern that this country will blow past Swedens death rate and exceed its case rate even further.
Some states, especially in the South, began easing restrictions in late April. But many people seemed to take bars and restaurants can reopen with capacity limits as back to normal! An entrenched culture of dont tell me what to do just about ensured the opposite of Swedes placing greater restrictions on themselves than the government did. And thats what happened.
In early-reopening Tennessee, 20- and 30-somethings packed Nashville clubs, skin-to-skin with scores of strangers (and few face coverings). That pattern repeated from pool parties at Lake of the Ozarks to bar openings, such as one in Michigan blamed for more than 100 cases.
Call it individualism, cultural libertarianism, atomism, selfishness, lack of social trust, suspicion of authority, The Week columnist Damon Linker wrote, it amounts to a refusal on the part of lots of Americans to think in terms of whats best for the community, of the common or public good. Each of us thinks we know whats best for ourselves. We resent being told what to do.
The White Houses coronavirus task force, led by Vice President Mike Pence, is now stressing that individual decisions to distance, wear masks, and practice good hygiene can reduce transmission, even as the Trump administration has not rolled out new strategies to address the skyrocketing case numbers in parts of the country.
Swedens light-handed restrictions, Kasson said, produced results similar to those in countries with stricter policies because so much of the population was willing to voluntarily self-isolate. In the U.S., even though phased reopenings have been accompanied by pleas from experts (but not necessarily state or local officials, at least initially) to social distance and wear face coverings, many people have said, nah.
After Memorial Day, social interactions in the U.S. began creeping up to half or more of what they had been during the period of the strictest mandates. By the beginning of April, people were already tiring of stay-at-home and were increasing their movement, said epidemiologist Jeffrey Shaman of the Mailman School of Public Health at Columbia University, so it actually predates the loosening of restrictions that began at the end of April.
Indeed, cellphone data show that, after a month of increases in social distancing, as of April 24, 48 states saw a drop, researchers at the University of Maryland found. Many Americans had said, enough.
Also missing from the U.S.: strong national policy, as Sweden has. Instead, each state and many cities were left to devise their own plans for the initial shutdowns and, especially, re-openings. Although there was federal guidance on what would be safe to do when, based on measures such as case counts and hospital capacity, many states ignored them. Social distancing varied enormously, the Maryland data show: In early May, its index of social distancing ranged from the 50s (on a scale from 0 to 100, with 100 being maximum distancing) in New York, New Jersey, and Massachusetts to the 30s or less in many Southern states.
As a result, risky decisions made in, say, Florida and Texas have started to bleed into surrounding states. We can see the virus moving along travel corridors, said CHOPs Rubin. Even though the number of cases is still low, you can see it in the R, the number of new cases each earlier case is causing.
Swedens Covid-19 messaging was also much clearer than that in the U.S. An important factor in shaping peoples behavior is how governments talk, said epidemiologist Jennifer Nuzzo of the Johns Hopkins Center for Health Security. If you talk about Covid-19 as a hoax, you can be pretty much assured that youll be on a path to a rapid acceleration of cases and deaths.
In the U.S., Pence has highlighted the fact that a larger percentage of new cases in states like Florida and Texas are occurring in younger people. But if the virus is spreading in one population, it wont be contained there. As cases rise among younger people, experts expect more transmission to reach older people. That is what happened in Sweden, driving up the countrys mortality rate. Probably because workers brought the virus into care homes for the elderly, Covid-19 raced through such facilities, which have accounted for about half of all deaths in Sweden; people over 70 accounted for some 90% of deaths.
Anders Bjrkman, an infectious disease expert at Stockholms Karolinska Institute, pointed to another problem that has plagued both the Swedish and U.S. response: a slow rollout of diagnostic testing. Both countries effectively limited testing initially to people who were really sick, which he called a clear mistake. Even now in the U.S., as demand has soared along with cases, some people are still unable to get tested or have to wait more than a week for results. That makes it harder for people to know if they should isolate themselves and tell their contacts to stay home as well.
And if an unstated goal of Swedens approach was to get closer to herd immunity, it does not appear to have been realized. Serology studies looking at how many Swedes have contracted the coronavirus and who are then, scientists hope, protected from another infection for some amount of time have ranged from about 6% to 14% in the Stockholm area (though some Swedish scientists say they believe the figure is higher than that based on different signals of immunity). That leaves the country far short of the 60% or so that experts say will slow down transmission.
I was surprised they didnt recalibrate as the serology findings came out, said University of Florida biostatistician Natalie Dean. My concern with Sweden is that theyre going to muddle along at this level and its not going to go down, for longer than the models say.
In the U.S., states outside the Northeast have started to pause their reopenings and, in some cases, reimposed some restrictions in an attempt to gain a handle over the spiraling outbreaks. But the effects of Americans version of Sweden are becoming alarmingly clear. In the CHOP model, current hot spots such as Miami and Houston get worse over the next few weeks. San Francisco and New Orleans surge, as do suburbs of Kansas City, Mo., and Chicago. Philadelphia and New York City also see an increase in cases.
Weve lost control at this point, said CHOPs Rubin. Unless we go back to the very early phase of our reopening, and do it quickly, the fall could be catastrophic.
