The UK-flagged Aurora cruise ship (pictured in a 2000 photo in Hamburg), 430 of whose 2,700 passengers and crew went down with a stomach bug off Croatia, is due to moor off Piraeus early today. Authorities will send doctors and supplies to the vessel, which will not be allowed to dock. The Health Ministry attributed the epidemic to the norovirus, which causes diarrhea, vomiting and nausea.
