OHA release - In early May, Oregon Health Authority (OHA) epidemiologists learned that an Oregon resident had been aboard the cruise ship MV Hondius, where health officials were investigating an outbreak of a rare virus called Andes hantavirus. Since then, OHA has worked closely with local, federal, and international partners to monitor the Oregon resident and plan for their safe return. The Oregon resident returned home on June 1 after staying 21 days at the National Quarantine Unit (NQU) at the University of Nebraska Medical Center. They will remain in home quarantine through June 21. This 42-day period follows their return to the United States on May 10, which is the incubation period for Andes hantavirus.
