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, 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.
Here's what you need to know about hantavirus including what it is, how it spreads, how it's treated and if there are any prevention methods:

An official from the Canarias Region government said that all passengers on the M/V Hondius will began to evacuate within the next 24 hours.
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.

The CDC is alerting doctors and health departments around the country to be aware of the potential for imported hantavirus cases from the cruise ship outbreak.
The agency notes that the risk of broad spread to the United States is considered extremely unlikely at this time.
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.
