That number dwindled to double digits in the summer.

The nation’s confirmed death toll, the second-highest in Europe after Britain’s, rose to 37,210 with the deaths of another 151 people.

The curfew is among a raft of measures that authorities hope will stem the resurgence of COVID-19 in a part of the world that suffered severely early in the pandemic.

Milan, Italy's business hub and the capital of the wealthy Lombardy region, has seen the sharpest rise in infections as the coronavirus once again is spreading out of control.

Further restrictions are set to take effect Monday. The Italian government is trying to prevent a repeat of the crisis the country experienced in the spring, when more than 30,000 people died and the hospitals at one point had more than 4,000 COVID-19 patients in intensive care.
