What makes ANDV different
Andes virus is the only hantavirus with documented person-to-person transmission, most recently characterised in a 2020 NEJM super-spreader study (Martinez et al.). All other hantaviruses require rodent contact. This makes ANDV in a closed environment — like a cruise ship — an elevated concern.
