Fears of virus on stranded cruise ship in Italy: mayor says 'waiting for results' More than 6,000 tourists are under lockdown aboard a cruise ship at an Italian port after two Chinese passengers were isolated over fears they could be carrying the coronavirus. Preliminary tests on the pair suggested they were not carrying the virus, the ministry of health said, but it was not immediately clear whether passengers would be allowed to leave the Costa Smeralda vessel before final results were confirmed.
