Show Caption Hide Caption Coronavirus quarantine: cases have tripled on a Princess Cruises ship The number of diagnosed cases of coronavirus on a Princess Cruises ship quarantined off the coast of Japan has tripled.

Six more passengers, including another American, have fallen ill on the Diamond Princess cruise ship that is quarantined off the coast of Japan, bringing the ship's total to 69 passengers who have been diagnosed with coronavirus.

The nationalities of the newly diagnosed passengers have not been revealed to Princess Cruises representatives, public relations director Negin Kamali told USA TODAY late Saturday.

The cruise ship is one of several affected by the deadly coronavirus outbreak, which has prompted cruise lines to issue quarantines and perform testings and screenings. Meanwhile, some ports are denying cruise ships entry for fear of the virus spreading.

The coronavirus, which was first identified in Wuhan, China, has spread across the globe with more than 34,963 confirmed cases and 725 deaths as of Saturday evening. The majority of the cases are in mainland China. Common signs of infection include fever, cough, shortness of breath and breathing difficulties.

The first American has died in China, the U.S. embassy in Beijing reported Saturday morning.

According to an earlier count announced before the six new cases were brought to light, 12 passengers diagnosed with coronavirus were Americans, the cruise line said. The ship is under quarantine until Feb. 19.

The ship, which had been off the coast of Yokohoma, Japan, is out to sea for a 24-hour period to produce fresh water.

Royal Caribbean listed new health screening protocols on its website Friday, noting "these steps are intentionally conservative, and we apologize that they will inconvenience some of our guests."

Cruise Lines International Association, an industry group representing most of the ocean-going cruise ships around the globe, said Friday its members would restrict boarding access to anyone who may have come in contact with coronavirus.

Member ships will deny boarding to anyone who has been in close contact with or helped to care for someone suspected or diagnosed with coronavirus. Those who are being monitored for potential exposure to the virus are also to be turned away.

Ships are also to deny boarding to all who have traveled from, visited or been through airports in China, the epicenter of the outbreak, within a two-week period prior to embarkation. That includes Hong Kong and Macao in addition to mainland China.

CLIA cruise member ships are to conduct screening before boarding. Enhanced screening and medical support are to be provided by ships as needed to anyone with coronavirus-like symptoms.

Crew members and passengers alike are subject to these precautionary measures.
