Hantavirus (Andes) vs Marburg
| Metric | ANDV | MVD |
|---|---|---|
| Case fatality rate | 30–40% | ~50% (range 24–88%) |
| R0 (basic reproduction number) | <1 (rare P2P clusters) | 1–2 |
| Incubation period | 2–4 weeks (up to 6) | 2–21 days |
| Transmission mode | Inhaled rodent excreta; rare person-to-person (ANDV only) | Direct contact with body fluids; bat exposure (caves) |
| Person-to-person spread | Limited | Yes |
| Treatment available | Supportive care, oxygen, ECMO; ribavirin investigational | Supportive care; investigational antibodies and antivirals |
| Vaccine available | None licensed | None licensed (Sabin/cAd3-Marburg in trials) |
| Geographic distribution | Argentina, Chile, with imported clusters worldwide (2026) | Sub-Saharan Africa; rare exports |
| First identified | 1995 | 1967 |
| Virus family | Hantaviridae (Bunyavirales) | Filoviridae |
| Reservoir host | Long-tailed pygmy rice rat (Oligoryzomys longicaudatus) | Egyptian rousette fruit bat (Rousettus aegyptiacus) |
Hantavirus (Andes virus, ANDV)
ANDVAndes virus is the only hantavirus with documented person-to-person transmission. The 2026 MV Hondius cluster is being closely watched because its cruise-ship setting matches the close-contact conditions where ANDV chains have appeared historically.

Marburg virus disease
MVDMarburg shares transmission and clinical features with Ebola but no licensed vaccine yet exists. Outbreaks have been small and contained through case isolation and safe burial practices.
