BAYONNE, N.J. (WHTM) — A Royal Caribbean cruise ship has docked in Bayonne, New Jersey with 12 passengers who have been quarantined due to concern over possible coronavirus infection.

WPVI Eyewitness News was there as the Anthem of the Seas arrived at 6 a.m. Friday in thick fog. Several ambulances were seen pulling up nearby.

The quarantined passengers will be tested by officials from the Centers for Disease Control, who were there upon arrival of the ship.

WPVI says the passengers, all Chinese nationals, started exhibiting symptoms aboard the ship, which is returning from the Bahamas.

A federal official tells Eyewitness News there is no indication any of the passengers actually have coronavirus, and that these steps are being taken out of an abundance of caution.

Since the outbreak began in Wuhan, China, the deadly respiratory virus has spread across Asia, Europe, and North America. The CDC says 11 people are confirmed to have the virus in the United States with dozens of other people being monitored.

There have been no confirmed cases in the tri-state area, but several people are being monitored.

In a statement, Royal Caribbean said: “We are participating in elevated levels of guest screening to check the spread of coronavirus. We are closely monitoring developments regarding coronavirus and have rigorous medical protocols in place onboard our ships.”

Officials say it is possible the people on the ship could have the flu.
