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.
