In Denmark, the coronavirus is everywhere, yet streets, cafes and shops are full. Tens of thousands have to isolate because they tested positive, but employees are back in offices, and bars and restaurants are no longer required to close at 11 p.m. or to ask for proof of vaccination.

On Saturday, thousands flocked to Copenhagen’s nightclubs, which reopened last week for the first time in nearly two months.

Nearly two years into the pandemic, in one of the world’s most prosperous nations, 5.8 million people live free of Covid restrictions, even though nearly 1 percent of them tested positive for the coronavirus in a single day last week. The country is reporting one of the world’s highest numbers of Covid-19 cases per capita, and hospitalizations have reached an all-time high.
