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:
What is hantavirus?
Hantaviruses are a family of viruses that can cause serious illnesses and death, according to the CDC.
How does hantavirus spread?
Hantaviruses may also spread from person to person, but that also is rare and only suspected for one subtype from South America, according to the WHO.

An official at the Centers for Disease Control and Prevention confirmed to ABC News that the agency will be dispatching personnel to the Canary Islands, where the M/V Hondius -- the cruise ship at the center of a suspected hantavirus cluster -- is scheduled to arrive on Sunday.
Teams will then escort those Americans to the National Quarantine Unit in Nebraska.

No U.S. residents have experienced any signs of illness as of Friday morning, according to health officials. However, six states are tracking nine residents for possible hantavirus infections.
Health officials in Texas, New Jersey and Georgia are monitoring two people while officials in California, Virginia and Arizona say they each are monitoring one person.
Two New Jersey residents -- who were not passengers on the cruise ship M/V Hondius -- are being monitored for possible hantavirus infections.
The state's health department was notified by the Centers for Disease Control and Prevention that the residents were potentially exposed to an infected cruise ship passenger during a flight. Neither individual is reporting symptoms.
This brings the total of U.S. residents under monitoring to at least nine across six states. None have shown any signs of illness at this time.

The State Department said Friday that it is in "direct communication with Americans on board" the Dutch cruise ship impacted by the hantavirus outbreak and "prepared to provide consular assistance as soon as the ship arrives in Tenerife, Spain."
The department added that it is arranging a repatriation flight to support the return of those American passengers.
The department said it was working in coordination with the U.S. Centers for Disease Control and Prevention, the U.S. Department of Health and Human Services, and the Spanish government to plan for the transport of those passengers.
Additionally, the department said it is still "closely tracking the hantavirus outbreak" on the MV Hondius and remains in "close contact" with the cruise ship staff and international health authorities.
