Top epidemiologist explains Sweden’s unorthodox strategy
Sweden has stood almost alone in Europe in avoiding a lockdown, and in relying on voluntary, trust-based measures to stem the spread of COVID-19. “As a society, we are more into nudging,” says Anders Tegnell, the epidemiologist behind the controversial strategy.

Experts look back on when everything seemed fine
Even some experienced infectious-disease experts did not fully appreciate how serious the COVID-19 outbreak would become. Some thought that the virus would be successfully contained in China, others were cautious about overreacting and some just couldn’t believe it could happen to them. “Everybody was in denial of this coming, including the U.S. And everybody got hit — just as simple as that,” says leading Canadian infectious-disease researcher Gary Kobinger.Read the latest coronavirus news, continuously updated on Nature.
