LISBON, Portugal — Portugal is restricting social gatherings to a maximum of five people.

It’s also making masks mandatory outdoors and will impose fines on those disregarding measures against the record numbers of coronavirus infections.

Some of the new measures will last initially 15 days and come under a state of calamity that came into force in the early hours of Thursday, a day after it was adopted by the Portuguese Cabinet.

Prime Minister Antonio Costa has called the surge in coronavirus cases as “serious” but has rejected imposing a strict lockdown.

Attendance at weddings, baptism ceremonies and other family functions will be limited to 50 people. Businesses that break rules on opening times and on serving of alcohol will face fines up to 10,000 euros ($11,700), twice as much as the current amount.

Portugal has more than 90,000 confirmed infections and 2,100 deaths.
