Global health authorities are working to contain an outbreak of hantavirus aboard the MV Hondius cruise ship.
The total number of confirmed cases associated with the outbreak is increasing, health officials said. To date, three people who were aboard the ship are known to have died of the virus.
More than 100 passengers remain on the ship, including 17 Americans, and the World Health Organization is monitoring their health. Officials said that the "overall public health risk remains low" but that there may be some person-to-person spread.
Health officials in multiple states say they're monitoring some passengers who have returned to the U.S. after being aboard the ship for potential hantavirus infections.
The vessel is expected to arrive in Tenerife and be anchored between 4:00 and 6:00 a.m. local time Sunday, according to the health ministry in Madrid.

The officials said that the government's plan is to not allow any of the passengers to put members of the population into any type of risk.
If passenger is not ready to be transferred directly to airplane of their destination, then they will not be able to leave the vessel, the officials said.
Leaving by nationality, passengers will be transferred to the port wearing full protective equipment to avoid any contact with Canarias territory and they will be escorted by a few buses via TF1 route to the airport, which will take approximately 15 minutes to reach the airport.

There have been no confirmed hantavirus cases associated with the cruise ship in the U.S. and at least nine residents are being monitored across six states, but none have shown any signs of illness at this time.
The CDC’s advisory to doctors, via the Health Alert Network (HAN) system, reminds them that in the event of a potential hantavirus case, patients should be placed in an isolated room and health care providers should use a gown, gloves, eye protection and an N95 mask or higher level respirator.
Doctors should also consider hantavirus infections as a potential diagnosis if a patient presents with hantavirus symptoms as well as known contact with an infected individual, officials said.
