Track global hantavirus outbreak dynamics in real time. Our interactive map shows current cases, deaths, and risk levels across all affected regions. Data is aggregated daily from official public health sources including the CDC, WHO, ECDC, and national health ministries.
Hantavirus is a family of viruses transmitted primarily by rodents. Different strains cause different diseases: Hantavirus Pulmonary Syndrome (HPS) in the Americas, and Hemorrhagic Fever with Renal Syndrome (HFRS) in Europe and Asia. Case fatality rates range from 1% (HFRS, Seoul virus) to 40% (HPS, Sin Nombre virus), making early detection and awareness critical for public health.
Each hantavirus strain is typically associated with a single reservoir species — usually a rodent, mole, or shrew. The virus does not make the animal sick, but the host sheds it in urine, droppings, and saliva for its entire life, creating persistent environmental contamination in nests, sheds, cabins, and storage areas.
Hantavirus has been reported on every continent except Antarctica. High-risk regions include:
Our live map visualizes active signals by region so travelers, researchers, and public-health teams can see where rodent-borne viral activity is clustering in 2026.
Humans typically contract hantavirus through:
The most common real-world exposure is cleaning a cabin, barn, or warehouse where rodents have nested: sweeping dry droppings stirs the virus into the air. This is why wet-cleaning methods are strongly recommended over dry sweeping.
HPS symptoms typically appear 1–8 weeks after exposure. Early signs include fatigue, fever, muscle aches (especially thighs and lower back), headaches, and dizziness. Within 4–10 days, coughing and shortness of breath can develop as fluid accumulates in the lungs. HFRS presents differently, with fever followed by low blood pressure, acute kidney injury, and reduced urine output. Anyone with rodent exposure who develops these symptoms should seek care and mention their exposure history. See our symptoms guide for a detailed clinical breakdown.
All data comes from official public health agencies:
We do not aggregate from social media or unverified sources. The goal is a centralized, transparent view that helps medical providers consider hantavirus early when patients present with febrile illness plus respiratory or renal distress.
The 2026 season arrives with overlapping ecological pressures: mast years that fuel rodent booms, extreme weather swings that reshape habitat, and continuing human encroachment into wild landscapes. Our tracker consolidates these signals so that a campground operator, a rural clinician, and a national agency can all see the same risk picture at the same time. Early, shared awareness is what converts a potential cluster into a contained event.

Use the alerts page to subscribe to free email notifications for the countries or regions you care about, and visit the reports page for historical statistics and country-level breakdowns. Travelers can check destination risk before trips, while public-health teams can corroborate local case reports against the global layer. The goal is simple: make verified hantavirus intelligence accessible to everyone, everywhere, every day.
