Passengers have begun evacuating the MV Hondius cruise ship that was hit by a rare hantavirus outbreak, boarding planes after the ship is docked in Spain’s Canary Islands.

The Dutch cruise ship, carrying about 150 people from 23 different nations, landed in the Spanish island of Tenerife on Sunday morning to begin disembarking its passengers and crew from the vessel. Eight people aboard the ship were diagnosed with the Andes strain of the hantavirus, the only strain thought capable of human-to-human transmission. Three people on the ship have died in the outbreak.
