The travel content creator from Boston was aboard the MV Hondius expedition ship when health officials identified an outbreak of the Andes strain of Hantavirus, a rare virus linked to several deaths connected to the voyage. Rosmarin is now spending 42 days in quarantine at the University of Nebraska Medical Center's National Quarantine Unit, a specialized facility designed for monitoring exposure to dangerous infectious diseases. Rosmarin said staff at the facility check temperatures and symptoms daily while passengers remain isolated inside individual rooms.

After a few days at the facility, Rosmarin was able order items online to decorate his unit with posters, and photos of his loved ones. The 29-year-old said while he hasn't tested positive and is not showing symptoms, the situation quickly became frightening once passengers learned people onboard had become seriously ill. They are hoping to give us the option to get tested at least once a week.

The quarantine period lasts 42 days due to the virus' long incubation window. Download the FREE Boston 25 News app for breaking news alerts. Rosmarin said despite the difficult circumstances, he's grateful for the care he's receiving.
