(EDITORS PLEASE NOTE - THE STORY HAS BEEN CORRECTED BECAUSE OF A REFERENCE TO THE WORLD HEALTH ORGANIZATION SAYING THERE ARE 44,000 CASES OF CONFIRMED CORONAVIRUS INFECTION IN CHINA ON MONDAY (FEBRUARY 17).
THIS WAS SAID IN ERROR AND THE REFERENCE HAS BEEN REMOVED.
PLEASE MAKE NO FURTHER USE OF THE PREVIOUS VERSION OF THIS VIDEO.) More than 300 Americans are back in the U.S. Monday, including 14 infected with the coronavirus, after being quarantined on a cruise ship that had the largest cluster of cases outside of China.
These images show passengers on board the Diamond Princess being cleared to disembark the ship after being detained at a Japanese port for two weeks, wearing surgical masks as they loaded buses - with workers in head-to-toe protective gear - before boarding two chartered jets that flew them to the U.S. Fourteen people tested positive for the virus while on the way back.
They were isolated in specialized containment areas on the planes.
One jet landed Sunday night at Travis Air Force Base in California, the other at Joint Base San Antonio in Texas.
The passengers will remain under quarantine another 14 days.
China has responded to the virus by locking down Hubei's provincial capital Wuhan - where the virus first appeared - a megacity of 11 million people.
It has also imposed restrictions in a number of other cities.
Outside of China, the WHO said it has received reports of 694 cases from 25 countries, with three deaths.
The organization's executive director warned one reporter that it is premature to label the coronavirus a "pandemic." (SOUNDBITE) (English) EXECUTIVE DIRECTOR OF WHO HEALTH EMERGENCIES PROGRAM MICHAEL RYAN SAYING: "I think we need to be extremely cautious in using the word 'pandemic.'
The real issue here is whether we're seeing efficient community transmission outside of China and at the present time we are not observing that.
The majority of cases outside China have a direct link still back to China.
So therefore I think that we have to be very, very careful not to drive fear in the world right now." Of the 3700 passengers on board the Diamond Princess, more than 400 tested positive for the virus.
That includes 40 Americans diagnosed days ago, who were prohibited from flying back to the U.S. They remain in Japan for treatment.
