After spending three weeks at UNMC’s National Quarantine Unit, five former passengers from the MV Hondius have returned to their home states for continued monitoring for the next 21 days under the jurisdiction of their local and state public health departments. Thirteen of the passengers remain in Omaha for monitoring. Because symptoms of Hantavirus can take up to 42 days to appear, all 18 of the former passengers were strongly encouraged to complete the entire period at the NQU.
