Cases by geography
Country-level and US state-level surveillance summaries. Each page combines current case counts with locality-specific context — dominant strain, rodent reservoir, ecology, and the public-health authority you should follow.
Argentina is the global focal point for Andes hantavirus.
Chile reports approximately 50–80 confirmed Andes hantavirus cases annually concentrated in the central and southern regions, with seasonal peaks in summer (December–March) when outdoor activity overlaps with peak rodent populations.
The United States has reported fewer than 900 confirmed HPS cases since surveillance began in 1993 (CDC NNDSS).
Germany reports the highest Puumala virus case load in Europe outside of Finland and Sweden, with strong year-on-year variability driven by beech-mast cycles.
Finland reports the highest Puumala virus incidence in the world per capita, with roughly 1,000–3,000 confirmed cases annually concentrated in northern Karelia, Savo, and Lapland.
China reports more hantavirus cases than any other country — typically 10,000 to 60,000 annually depending on the cycle phase — concentrated in Heilongjiang, Shaanxi, Yunnan, and Hubei provinces.
South Korea reports approximately 300–600 confirmed Hantaan virus HFRS cases annually, concentrated in Gyeonggi, Gangwon, and Chungcheong provinces.
Brazil reports approximately 80–150 confirmed HPS cases annually, with the highest incidence in southern and central-western states — especially Mato Grosso, Paraná, and Rio Grande do Sul.
