Over 6,000 tourists were blocked on a cruise ship in Italy on Thursday after the vast liner was placed on lockdown over two suspected cases of the deadly coronavirus. Samples from a Chinese couple were sent for testing after three doctors and a nurse boarded the Costa Crociere ship in the port of Civitavecchia to tend to a woman running a fever, the local health authorities said. Costa Crociere confirmed the ship, carrying some 7,000 people including the crew, was in lockdown. ide/wdb
