How we verify data
Every event entry is constructed from verbatim quotes in primary sources. We do not estimate; where a numeric claim cannot be verified against an open-access tier-1 source, we record zero. Tier-1 sources: WHO, CDC, ECDC, PAHO, national health ministries. Tier-2: ProMED-mail, CIDRAP, peer-reviewed papers. Tier-3 (queues for manual review): major science journalism (Reuters, AP, BBC).
Hantavirus species at a glance
Hantavirus is a family of rodent-borne RNA viruses (Hantaviridae). The clinically important species split between Hantavirus Pulmonary Syndrome (Andes, Sin Nombre, Bayou, Black Creek Canal, Choclo, Laguna Negra) and Hemorrhagic Fever with Renal Syndrome (Hantaan, Puumala, Seoul, Dobrava). Case-fatality varies dramatically by species — from <0.5 % for Puumala to ~30–40 % for Andes and Sin Nombre.
