Medical disclaimer

This site provides educational information about hantavirus. It is not a diagnostic tool and cannot replace evaluation by a qualified healthcare professional.

Information here may not reflect the very latest reports from public-health authorities. For decisions about your health, follow your national public-health agency and consult a clinician.

Map shading reflects educational risk categories drawn from the cited sources. It does not assess your personal risk of infection. Grey shading indicates that no curated dataset is shown, not that a country is virus-free.

If you have breathing difficulty, chest tightness, fainting, confusion, severe weakness, or rapidly worsening illness — especially after possible rodent exposure — seek urgent medical care and tell healthcare staff about the exposure.
