Denmark stands out for its fast and effective response to the virus, leaving it with a death rate that’s roughly a fifth that in neighboring Sweden. But Danes aren’t required to wear face masks, and local authorities generally don’t recommend them.

Henning Bundgaard, chief physician at Denmark’s Rigshospitalet and a professor in cardiology, is finalizing a study that explores how effective face masks are outside hospitals in halting the spread of the virus. He says research conducted before the pandemic hit isn’t conclusive. “All these countries recommending face masks haven’t made their decisions based on new studies,” Bundgaard said in an interview in Copenhagen. He says there’s evidence to suggest that the only effective face covering might be a visor, because the virus can spread through all mucous membranes, including via the eyes. He worries a cloth covering that only protects the nose and mouth provides a “false sense of security.”
