Risk check
Am I at risk?
Tell us where you've been. We'll check it against confirmed cases from the 2026 outbreak.
Not medical advice. This tool compares your reported visit to publicly reported cases and known endemic regions. It is not a clinical assessment, can't account for unreported cases or personal exposure factors (rodent contact, immune status, etc.), and shouldn't be used to make medical decisions. If you have symptoms or specific concerns, contact a clinician or your local public-health authority.
Common questions
Should I be worried?
Probably not. Most people who use this tool aren't near any confirmed cases — the 2026 outbreak is concentrated in specific places, and the check will tell you plainly if you weren't anywhere close. If you do get a higher tier, it doesn't mean you're sick; it means it's worth knowing the symptoms to watch for.
What symptoms should I watch for?
Early symptoms look like the flu: fever, severe muscle aches, fatigue, and headache. They typically appear 1 to 8 weeks after exposure. Later symptoms include a dry cough, shortness of breath, or rapid breathing. If you develop any of these after a higher-risk visit, contact a clinician and mention possible Hantavirus exposure — early treatment makes a real difference.
How is Hantavirus actually spread?
Almost always by breathing in dust contaminated with rodent urine, droppings, or saliva — usually in enclosed rural or rodent-infested spaces, often while cleaning. Andes virus (ANDV), the strain in the 2026 outbreak, is the only hantavirus with documented person-to-person transmission, and that's still rare.
How does this risk check work?
We measure the distance from where you were to every confirmed case in our dataset, and we only count cases reported within ±8 weeks of your visit — the upper bound of the incubation window, plus a buffer for delayed reporting. The closest case in that window drives the score. Being in a country where Hantavirus circulates adds a small baseline.
What do the risk tiers mean?
High or Elevated means a confirmed case was reported very close to where you were, during the relevant time window. Moderate means cases in the broader region. Low means background only — your country has documented Hantavirus circulation, but nothing specific to your location. Very low means no nearby cases in your window.
Where does the data come from?
Confirmed cases come from the GISAG ANDV 2026 ArcGIS dashboard, which draws on WHO Disease Outbreak News, the Swiss Federal Office of Public Health (BAG), CBC, and verified press reports. Each case links back to its original source. The full dataset is at hantatracking.com/api/cases.
Is this medical advice?
No. This is a comparison tool, not a clinical assessment. It can't account for unreported cases or personal exposure factors like rodent contact or immune status. If you have symptoms or specific concerns, contact a clinician or your local public-health authority.
The data behind this check
The Hantavirus outbreak data we compare against is the same dataset powering the live tracker map and is published as JSON at /api/cases. It currently focuses on the 2026 ANDV (Andes virus) outbreak — the MV Hondius cruise-ship cluster and downstream cases in Switzerland, the Netherlands, South Africa, Singapore, the United Kingdom, the United States, Cape Verde, and Argentina — sourced from WHO Disease Outbreak News, the Swiss Federal Office of Public Health (BAG), the GISAG ArcGIS dashboard, and verified press reports.
