David Abel’s 50th wedding anniversary luxury cruise began with him eating his fill and enjoying the sights of East Asia. Abel is among hundreds of passengers on two cruise ships in Japan and Hong Kong who are caught in the drama and fear about the little-understood, but fast-spreading new type of coronavirus. The ship has been placed under a two-week quarantine following an outbreak on board of the deadly coronavirus that has killed more than 630 people in China. Passengers have been confined to their cabins, left to fight off a mix of anxiety and boredom. Some have been posting updates on conditions on board the ship on social media. Other passengers posted images of sparse meals, crew in face masks and once bustling common areas now eerily deserted. On Wednesday night the ship was allowed to dock at the Japanese port city of Yokohama and take on much needed supplies. Medical teams on board have been screening passengers for signs of the virus. So far, 20 passengers diagnosed with the coronavirus strain have been removed and taken to hospital.
