A cruise ship docked in Greece that caused a coronavirus scare, was given the all-clear by Greek authorities on Tuesday after a "false alarm". Crew members suspected of being infected with the novel virus, tested negative. The Maltese-flagged Mein Schiff 6, operated by Anglo-German travel giant TUI, is the first cruise ship to sail in Greece after a 6-month suspension. Mein Schiff 6 is carrying 922 passengers and 666 crew. On Monday, a dozen staff members were 'found' to be positive for coronavirus but asymptomatic. Sailing off the island of Milos, the ship was then redirected and forced to dock at Piraeus early on Tuesday. Staff members were given three more tests each, all of which came back negative, Greece's Deputy Minister for Civil Protection & Crisis Management, Nikos Hardalias told reporters. "We then sounded the end of the alert," he added. Health and Epidemiology Professor Gkikas Magiorkinis, a member of the government's pandemic expert committee, said that "there is now no concern over this particular cruise ship. We also tested surfaces on the ship and all surfaces tested are negative." The ship is expected to continue its journey on Wednesday.
