Italy took a page from China’s playbook Sunday, locking down around 16 million people — more than a quarter of its population — for nearly a month to halt the relentless march of the new coronavirus across Europe.

Weddings, museums, movie theaters shopping malls, and even restaurants are all hit by the new restrictions, which focus on a swath of northern Italy but are disrupting daily life around the country. After mass testing uncovered more than 7,300 infections, Italy now has registered more cases of the virus than any country but China, where it’s now on the retreat.

From Venice to Milan, confusion reigned as residents and tourists tried to figure out when and how the new measures were coming into effect. Travelers crammed aboard standing-room only trains, tucking their faces into scarves and sharing sanitizing gel.

Around the globe, more and more events were canceled or hidden behind closed doors, from the pope’s Sunday service to a Formula One car race in Bahrain and a sumo competition in Japan. Questions grew about whether to maintain U.S. presidential campaign rallies and other potentially “super-spreading” gatherings, as the virus stretches into new states.

Italian Premier Giuseppe Conte signed a quarantine decree early Sunday for the country’s prosperous north. Areas under lockdown include Milan, Italy’s financial hub and the main city in Lombardy, and Venice, the main city in the neighboring Veneto region. The extraordinary measures will be in place until April 3.

The fate of foreign visitors stuck in Italy’s new quarantine zones is still unclear.
