Passengers onboard the MV Hondius cruise ship began disembarking on Sunday morning in Tenerife, in the Canary Islands, where they were expected to continue on to charter flights back to their home countries.
The total number of confirmed and probable cases of hantavirus onboard the ship is eight, including two people confirmed to have died from the virus and one person who remains suspected to have died from the virus.
There are 17 U.S. citizens aboard the ship who will be returning to the United States. As of Saturday none of them had tested positive for the hantavirus, according to the Centers for Disease Control and Prevention (CDC).
A CDC official said Saturday that the federal government doesn't plan to have the repatriated American cruise ship passengers quarantine upon arrival in the U.S.

The MV Hondius is now expected to arrive at Granadilla Port on Sunday by 12 p.m. local time, but could be delayed depending on weather conditions, officials said.
The ship will not dock upon arrival but will be anchored, and all passengers will be wearing hazmat gear as they are transferred by boat to the port, according to a statement from the Canarias Region government.
The passengers will then be transferred by a bus that is escorted by authorities to the airport where they will begin boarding aircraft by nationality with 23 nationalities on board in total, officials said.
The ride between Granadilla Port and Tenerife South Airport is expected to last approximately 15 minutes and officials said that passengers, as well as the vessel, will be completely isolated from Canarian people and not affect any local infrastructure.

The U.S. Centers for Disease Control and Prevention (CDC) activated its Emergency Operations Centers and has classified the hantavirus outbreak as "Level 3," multiple sources told ABC News.
That's the lowest level of emergency activation and is typical for this stage. It signifies the risk to the general public remains low, but the situation is being actively monitored by the public health agency.
Activating the Emergency Operation Centers indicates that an emergency team has been set up to support a response. Epidemiologists, scientists and physicians may have been re-assigned from their typical roles to assist with the response.
