Italy's government has expanded travel restrictions to the entire country, locking down some 60 million people in an effort to contain the coronavirus.
Prime Minister Giuseppe Conte said in a televised address Monday evening that the quarantine measures could be summarized by the phrase "I'm staying home."
The move expands Italy's travel restrictions from the north of the country where the outbreak first took hold. Only people with valid work or health reasons will be allowed to travel between regions in Italy or to other countries.
"Our habits need to change," Conte said. "They need to change now."
The changes go into effect Tuesday, and include a requirement that all restaurants and cafes close by dusk. The number of coronavirus cases in Italy rose Monday to 9,172, overtaking South Korea as the country with the most number of cases outside of China. The death toll from the virus in Italy increased to 463.
Earlier Monday, the leader of the World Health Organization said that the deadly coronavirus has gained a foothold in so many countries that "the threat of a pandemic has become very real."
But WHO Director-General Tedros Adhanom Ghebreyesus voiced optimism as well, saying it "would be the first pandemic in history that could be controlled." He concluded, "The bottom line is: We are not at the mercy of this virus."
But the impact from the coronavirus was unabated, and the WHO said that more than 100 countries are now reporting coronavirus cases. The total number of cases worldwide has surpased 114,000 while the death toll has topped 4,000.
Tedros said that with "decisive, early action," world leaders can slow the advance of the illness and prevent infections. He said that "among those who are infected, most will recover," noting that in China, where the disease was first reported, more than 70% of the 80,000 victims have recovered and been discharged from further treatment.
Also Monday, a cruise ship off the U.S. West Coast docked in the Californian city of Oakland Monday after some of the passengers on board tested positive for the virus.
Local and federal officials have developed a plan for handling the passengers and crew on the Grand Princess cruise ship, including moving the California residents to military facilities in the state to wait out a 14-day quarantine, while transporting residents of other states to bases in Texas or Georgia.
The U.S. Centers for Disease Control and Prevention said the State Department is working with the home countries of several hundred foreign passengers to arrange getting them home.
The cruise line said the crew will remain on the ship and depart after the passengers leave.

"We have a perfectly coordinated and fine- tuned plan at the White House for our attack on CoronaVirus. We moved VERY early to close borders to certain areas, which was a Godsend.
