90-Second Read: WATCH: CDC gives update on Hantavirus-exposed cruise passengers at Nebraska Medicine

A plane carrying 18 Americans exposed to Hantavirus on a cruise ship in Spain arrived at Eppley Airfield just before 2:30 a.m. According to Nebraska Medicine, this facility is the only federally funded quarantine unit in the United States, a place to safely house and monitor those who may have been exposed to high-consequence infectious diseases. According to the CDC, passengers will not be placed under quarantine upon their arrival at the UNMC-Nebraska Medicine campus. Members of the CDC said the one passenger who tested positive later tested negative for Hantavirus. That passenger is being retested, and the results are expected back "in a day or so." They clarified that there are no state or federal quarantine orders, and the CDC is working with contacts to make sure they know.

State and local health partners have been checking on the people exposed multiple times daily. Some US citizens had left the Dutch cruise ship MV Hondius prior to the outbreak being detected and "may have gone home on commercial flights. Also, the CDC declined to specify how many people were exposed who are not in Nebraska or Atlanta (where the CDC is headquartered) out of privacy. The CDC activated an emergency response in Atlanta immediately and has more than 100 staff actively working on the response. There are 20 300-square-foot rooms fitted with negative air pressure systems that will contain any possible viruses.

People in the UNMC facility are being encouraged to stay, but the CDC would not state if the people are required to stay in quarantine there. Another team has come to Nebraska and was there when the plane landed with the 18 Americans. They have been conducting assessments and supporting the passengers. The passengers have been housed in the National Quarantine Unit. A CDC team was also deployed to the Canary Islands and spoke with each US citizen about potential exposure.

Instead, they'll be monitored and assessed for a shorter stay, then likely go home for a self-monitoring period.

UNMC's interim chancellor said Monday that each passenger's exposure varies, and their team is ready to handle whatever gets thrown their way.
