90-Second Read: 18 US passengers sent to Nebraska, Atlanta amid Hantavirus outbreak

At least 18 people are currently under observation at two of the nation's top medical centers after being potentially exposed to Hantavirus aboard the MV Hondius, the cruise ship at the center of the deadly outbreak. According to public health officials, 18 passengers who disembarked the cruise ship on Sunday returned to the United States. The patient in the Omaha, Nebraska, biocontainment unit tested positive before arriving back in the United States and is one of nine people worldwide who have tested positive in connection with the outbreak, according to the World Health Organization.

Georgia Department of Public Health Communications Director Nancy Nydam said she could not provide information on whether the pair had tested positive for Hantavirus.

WHO investigators believe the outbreak stemmed from a Dutch couple on board the ship who came in close contact with wildlife carrying the virus before boarding the vessel. Health experts say the current outbreak poses little risk to the general public. Most went to the University of Nebraska Medical Center, where one is in the center's biocontainment unit and 15 are in quarantine.
