France imposed a 15-day lockdown on its citizens, with President Emmanuel Macron saying in a speech on Monday: “We are at war.”

And it’s not just national borders. Europeans are erecting boundaries inside their cities and neighborhoods and around their homes. A life of “bumping shoulders on the street or in the cafe, greeting friends with kisses on the cheeks” is no more, writes our chief diplomatic correspondent in Europe.

Here are the latest updates on the outbreak and maps of where the virus has spread.

Elsewhere around the world:

President President Trump and U.S. health officials advised against gatherings of more than 10 people and discouraged young people in particular from going to bars and restaurants. Millions of people in the San Francisco area were ordered to “shelter in place.”

Canada closed its borders to most foreign travelers.

In a reversal, British prime minister Boris Johnson said people should work at home and avoid unnecessary travel and contact with others, but stopped short of ordering schools or businesses closed.

President Trump told a group of governors they should not wait for the federal government to fill the growing demand for respirators for severe coronavirus cases.

Across the Middle East, schools, malls, restaurants and workplaces were shuttered and flights were suspended as countries like Saudi Arabia, Lebanon and Kuwait moved aggressively to deal with the outbreak.
