BANGKOK, Feb. 12 (ABCNews) - Passengers on board Holland America's Westerdam cruise ship will remain stuck at sea, after approval to dock in Bangkok was revoked.

The cruise ship, which left Hong Kong on February 1, has already been refused entry to the Philippines and Japan and numerous ports in Taiwan, as well as South Korea and Guam.

Port authorities have cited fears that passengers may be carrying the coronavirus, despite the ship's operators saying they have "no reason" to believe there are any cases on board.
