Teams will bring back Americans to the National Quarantine Unit in Nebraska.
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:
Hantaviruses are a family of viruses that can cause serious illnesses and death, according to the CDC.
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.
Anais Legand, the technical officer with the World Health Organization, briefed the press Friday about the organization's efforts to screen the M/V Hondius' crew and passengers after the ship arrives in the Canary Islands.
Health teams will work with national authorities and each boat member will be assessed by trained medical staff, he said.
Epidemiologists will review individual exposure histories and interactions, according to Legand.
"So this is a way for us to get all the pieces together and have the maximum information to be able to assess any risk for this person and give them the right recommendation," he said.
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.
