Another evacuee from the hantavirus-hit cruise ship has been confirmed to have the deadly disease, according to Spain's health ministry.
A Spaniard, who was quarantining in Madrid after being evacuated from the luxury MV Hondius, provisionally tested positive for the rat-borne disease on Monday.
It marks the third case of previously symptomless passengers testing positive after they were repatriated to their home countries.
On Monday, an American and a French national who had previously returned home tested positive.
The French woman, who had no initial symptoms, is now in 'serious condition' with hantavirus, according to the French government, after her health rapidly declined in hospital.
And a second American national on Sunday's repatriation flight has also shown mild symptoms, according to the US health department, who added that both passengers travelled back in 'biocontainment units out of an abundance of caution'.
The cruise ship left Tenerife for the Netherlands on Monday after its final six passengers - four Australians, one Briton and one New Zealander - and some crew members were evacuated.
Three people - a Dutch couple and a German woman - have died after travelling on the vessel, two of whom were confirmed to have had the virus.
