THE CLEANEST AND DIRTIEST CRUISE SHIPS, ACCORDING TO THE CDC

In response to the outbreak, American-owned cruise lines and resorts are suspending operations until the situation is contained.

Royal Caribbean International, the world's largest cruise line, initially announced it would not allow Wuhan residents or individuals who have recently traveled through the town to board its ships, according to The Wall Street Journal. The company is committed to helping guests modify itineraries, a spokesman told the publication.

By Saturday, Royal Caribbean canceled its Jan. 27 sail on the 1,139-foot Spectrum of the Seas ship, which was scheduled to set sail from Shanghai to Japan, according to Cruise Industry News.

Carnival Cruise Line's medical team is in talks with the Centers for Disease Control and Prevention and the World Health Organization about passenger health screenings, monitoring and ship protocols, according to a Carnival spokesman said.

The screening may include temperature checks and questionnaires for passengers entering from China, though, plans have not been finalized at the time of publication.

HOW TO PREVENT CORONAVIRUS FROM SPREADING

Norwegian Cruise Line, on the other hand, has introduced non-touch temperature screenings for all passengers boarding its ships from Chinese ports to prevent the flu-like virus from spreading. Those who have a body temperature of 100.4˚F will not be allowed to board.

Individuals who have lived or traveled through Wuhan in the last 30 days will be turned away as well, according to a report from the International Business Times.

Celebrity Cruises and Costa Crociere echoed similar prohibitive policies for sick and unafflicted passengers who have been through Wuhan as of late, as obtained by industry news website Cruise Critic on Thursday.

However, Costa canceled a series of cruises throughout Europe that were scheduled for the end of the month and early February – which may have to do with France's confirmed coronavirus case on Friday. Passengers are being offered refunds or alternative sailing dates.

STOCKS TUMBLE AS CORONAVIRUS SPREADS

Geneva-based MSC Cruises has also followed suit with its Jan. 28 sail from Shanghai.

FOX Business reached out to Disney Cruise Line and Adventures by Disney – other major players in the commercial sailing industry – to see if its passenger vessels will take precautions to curb outbreaks among guests. FOX Business did not receive a response at the time of publication.

Chinese-owned Astro Ocean Cruises is offering refunds to anyone who has a fever while Genting Dream has canceled a turnaround call in Guangzhou for its World Dream ship.

Halting of outbound travel from China may have an impact on the cruise industry since the massive country is a source market throughout American and European cruise lines.

Last year's report from the Cruise Lines International Association found that 28.2 million people took a cruise in 2018. Of that number, 2.4 million were cruisers from China.
