This comes after all confirmed cases of the new coronavirus aboard cruise ships have been on Princess vessels. The Diamond Princes has been docked in Yokohama, Japan, with at least 700 confirmed cases. The Grand Princess docked Monday in Oakland, California, has about 21 confirmed cases.

In proactive response to the unpredictable circumstances evolving from the global spread of COVID-19 and in an abundance of caution, Princess Cruises announced that it will voluntarily pause global operations of its 18 cruise ships for two months (60 days), impacting voyages departing March 12 to May 10.

"Princess Cruises is a global vacation company that serves more than 50,000 guests daily from 70 countries as part of our diverse business, and it is widely known that we have been managing the implications of COVID-19 on two continents," said Jan Swartz, president of Princess Cruises.

"By taking this bold action of voluntarily pausing the operations of our ships, it is our intention to reassure our loyal guests, team members and global stakeholders of our commitment to the health, safety and well-being of all who sail with us, as well as those who do business with us, and the countries and communities we visit around the world," added Swartz.
