Hantavirus: From Rodent Infection to Holiday Hell

To understand the threat posed by hantaviruses to humans following a recent outbreak on a Dutch cruise ship.

Rodents are the likely original source of the recent hantavirus outbreak, with genomic evidence supporting a single zoonotic spillover event.
Person-to-person transmission of hantaviruses is rare but has been documented, particularly with Andes virus.
Diagnosis of hantavirus infection relies on clinical presentation, exposure history, and laboratory testing, including PCR and serologic methods.

Current genomic data cannot completely exclude the possibility of multiple passengers being infected from the same environmental source.
Further environmental investigations are needed to clarify the initial exposure and identify specific rodent reservoirs.
