MADRID -- Spanish Secretary of State for Health Javier Padilla said on Friday that the health authorities had taken relevant measures after detecting a suspected case of hantavirus in the eastern city of Alicante.

The person traveled several weeks ago on the same flight as one of the infected individuals, Padilla said.

He added that the person had developed symptoms compatible with hantavirus infection, although the authorities are still assessing whether the case can be confirmed.

In addition, Padilla confirmed that all 14 Spanish passengers aboard the MV Hondius had agreed to undergo voluntary quarantine measures in order to minimize the risk of further transmission.

The Dutch-operated expedition cruise ship, currently heading toward Spain's Canary Islands, has so far been linked to three deaths.

Padilla said a team from the Spanish Health Ministry would travel to Tenerife on Saturday ahead of the ship's expected arrival on Sunday.

Passengers are expected to disembark by small boats before being transferred under strict isolation measures. Spanish citizens aboard the vessel will be transported to Madrid for quarantine observation.
