Some 2,000 people were called back on board the MSC Opera from an excursion in Athens today and told not to leave the ship.
Once they returned, the captain revealed that an Austrian tourist who left the ship on February 28 had been infected with the virus.
The virus patient, a man, had disembarked in Genoa in northern Italy, the region at the centre of the coronavirus outbreak in Europe.

One passenger, Antonio Montalto, said guests had been told to return to the vessel ‘immediately’ from their excursion in Greece.
The order was initially unexplained, and rumours even swirled that the delay was linked to the tensions on the Greece-Turkey border.
However, the captain subsequently explained that passengers had been called back over virus fears.
The passenger later said that the cruise appeared to be continuing ‘regularly’ and was still due to arrive in Corfu tomorrow.
A letter from the captain, seen by the Mirror, said that the ship’s crew was ‘waiting for further clarity and guidelines’ from Greek and Austrian authorities.
‘All passengers and crew are requested to remain on board until we have further clarity on the matter,’ the letter says.
‘Please note there is no reason for concern. We have no indication that suggests there may be an issue currently on board MSC Opera and there are no cases that suggest there may be a case of Covid-19.’

The attempted two-week quarantine on the Diamond Princess was widely criticised by experts after 705 people tested positive.
