Videos broadcast from cruise ships were among the first images the world had of the spreading novel coronavirus.
The US Centers for Disease Control and Prevention (CDC) issued a no-sail order to cruise companies on March 14.
It notes outbreaks of COVID-19 on cruise ships also pose a risk because passengers can spread the disease into communities across the world after disembarkation.
Shares of the three major cruise lines, Carnival, Royal Caribbean, and Norwegian cruise lines, have plunged between 60 and 75 per cent this year.
Royal Caribbean Cruises suspended its global operations on March 13, a day before the CDC order went into effect, and was forced to cancel 130 cruises during the quarter.
