MADRID — Authorities in Spain’s northeastern region of Catalonia are considering a mandatory stay-at-home order for weekends only, one of the strictest measures being imposed across the country to combat a sharp resurgence of the coronavirus.

Under a new state of emergency declared by the national government on Sunday, Spain’s 17 regions and two autonomous cities can tailor restrictions that include a nationwide overnight curfew, a cap of six people on social gatherings and possible regional travel bans.

Only Spain’s Canary Islands, where the curve of contagion has been kept at bay, will be exempted from the 11 p.m.-6 a.m. general curfew, which other regions’ officials can decide to push one hour earlier or later.

The aim is to rein in infections from gatherings of family and friends at home or in bars.

The Spanish government wants the state of emergency to be extended later this week until May with as many votes as possible in the country’s parliament.

Spain last week became the first European country to surpass 1 million officially recorded COVID-19 cases, although officials say that the real figure could be way above 3 million.
