How many hantavirus cases worldwide in 2025?

In 2025, hantavirusmap.io tracked 101 confirmed cases across 1 distinct outbreak events, with 0 deaths recorded.

The dominant signals were Argentina's annual ANDV season (typically peaking November–April in the Patagonian and northeast provinces), sporadic SNV cases across New Mexico, Colorado, Arizona and Utah, and an elevated Puumala-virus year in Finland and Sweden following a vole-population peak.

Comprehensive global surveillance for hantavirus is incomplete. Russia and China — historically the largest contributors to global HFRS case counts — publish at low temporal resolution, and many tropical-American countries report only when laboratory-confirmed clusters reach health ministries. Treat these figures as a public-health record of reported events, not as an estimate of true incidence.
