Hantavirus (Andes) vs Ebola
| 指標 | ANDV | EVD |
|---|---|---|
| 致命率 | 30–40% | ~50% (range 25–90%) |
| R0（基本再生産数） | <1 (rare P2P clusters) | 1.5–2.5 |
| 潜伏期間 | 2–4 weeks (up to 6) | 2–21 days |
| 感染経路 | Inhaled rodent excreta; rare person-to-person (ANDV only) | Direct contact with body fluids; safe-burial practices critical |
| ヒトからヒトへの感染 | 限定的 | あり |
| 治療法の有無 | Supportive care, oxygen, ECMO; ribavirin investigational | Two monoclonal antibody therapies licensed (Inmazeb, Ebanga); supportive care |
| ワクチンの有無 | None licensed | Ervebo (rVSV-ZEBOV, licensed 2019); Zabdeno/Mvabea regimen |
| 地理的分布 | Argentina, Chile, with imported clusters worldwide (2026) | Sub-Saharan Africa; sporadic exports |
| 最初の確認年 | 1995 | 1976 |
| ウイルスファミリー | Hantaviridae (Bunyavirales) | Filoviridae |
| 保有宿主 | Long-tailed pygmy rice rat (Oligoryzomys longicaudatus) | Fruit bats (suspected); primates amplifying host |
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.

Ebola virus disease (Zaire)
EVDEbola is highly lethal but requires direct contact with body fluids to transmit. The licensure of Ervebo in 2019 and effective monoclonal antibodies have transformed outbreak response.
