China placed 50 million people under quarantine in Wuhan Province in January. Since then, many liberal democracies have taken aggressive authoritarian measures of their own to fight the novel coronavirus. By mid-March, almost all Organization for Economic Cooperation and Development (OECD) countries had implemented some combination of school, university, workplace, and public transportation closures; restrictions on public events; and limits on domestic and international travel. One country, however, stands out as an exception in the West.
Rather than declare a lockdown or a state of emergency, Sweden asked its citizens to practice social distancing on a mostly voluntary basis. Swedish authorities imposed some restrictions designed to flatten the curve: no public gatherings of more than 50 people, no bar service, distance learning in high schools and universities, and so on. But they eschewed harsh controls, fines, and policing. Swedes have changed their behavior, but not as profoundly as the citizens of other Western democracies. Many restaurants remain open, although they are lightly trafficked; young children are still in school. And in contrast to neighboring Norway (and some Asian countries), Sweden has not introduced location-tracing technologies or apps, thus avoiding threats to privacy and personal autonomy.
Swedish authorities have not officially declared a goal of reaching herd immunity, which most scientists believe is achieved when more than 60 percent of the population has had the virus. But augmenting immunity is no doubt part of the government’s broader strategy—or at least a likely consequence of keeping schools, restaurants, and most businesses open. Anders Tegnell, the chief epidemiologist at Sweden’s Public Health Agency, has projected that the city of Stockholm could reach herd immunity as early as this month. Based on updated behavioral assumptions (social-distancing norms are changing how Swedes behave), the Stockholm University mathematician Tom Britton has calculated that 40 percent immunity in the capital could be enough to stop the virus’s spread there and that this could happen by mid-June.
