This is the live count of hantavirus cases reported worldwide as of 2026-05-13. Only cases confirmed by an official WHO Disease Outbreak News (DON) are counted as "confirmed". Suspected and probable cases extracted from peer-reviewed publications are tracked separately.

What is hantavirus?

Hantaviruses are a family of zoonotic RNA viruses transmitted primarily by rodents. They cause two main clinical syndromes: Hantavirus Cardiopulmonary Syndrome (HCPS) in the Americas — typically caused by the Sin Nombre and Andes strains, with a case fatality rate of 35–50% — and Hemorrhagic Fever with Renal Syndrome (HFRS) in Eurasia — Hantaan (CFR 5–15%), Puumala (CFR <1%), Seoul (CFR 1–2%), Dobrava (CFR 10–12%). ICD-10 code: A98.5.

How we count hantavirus cases

Hantacase aggregates hantavirus case counts every 2 hours from the following official sources:

WHO Disease Outbreak News (the only "confirmed" tier source)
ECDC Communicable Disease Threats Report (Europe)
US CDC MMWR + Emerging Infectious Diseases journal
PAHO surveillance (Americas)
National health authorities: Santé Publique France, UKHSA, RKI (Germany), KDCA (South Korea), Public Health Canada
Peer-reviewed: PubMed, Eurosurveillance, EID Journal, NEJM, Lancet
Verified press: Reuters Health, AP News, BBC, ProMED, CIDRAP, Outbreak News Today

A case is marked confirmed only if it appears in an official WHO DON. Other signals are tagged suspected (peer-reviewed publication) or rumor (press only). Full methodology →
