Hantaan virus
Hantaan virus is the prototype species, causing classic hemorrhagic fever with renal syndrome with up to ~10% case fatality in untreated cases.
Hantaan virus is the prototype species, causing classic hemorrhagic fever with renal syndrome with up to ~10% case fatality in untreated cases. Reservoir: striped field mouse (Apodemus agrarius). Highest case loads occur seasonally in China and Korea.
Active and recent clusters
- China · Shaanxi / Heilongjiang / Yunnan — 11000 cases, 110 deaths (CFR 1%) · Annual pattern; China CDC weekly bulletin. China reports more hantavirus cases than any other country — typically 10,000 to 20,000 confirmed HFRS cases annually depending on the cycle phase. Hantaan virus dominates in agricultural regions; Seoul virus in port cities. China uses a bivalent inactivated Hantaan/Seoul vaccine in high-incidence rural counties.
- South Korea · Gyeonggi / Gangwon — 400 cases, 12 deaths (CFR 3%) · Annual pattern; KDCA infectious disease portal. South Korea reports approximately 300–600 confirmed HFRS cases annually, concentrated in Gyeonggi, Gangwon, and Chungcheong provinces. The disease (Korean hemorrhagic fever) gave its name to the prototype Hantaan virus. KDCA uses inactivated Hantaan vaccine in high-risk military and rural populations.
Frequently asked

Is Hantaan virus contagious between people?
No documented person-to-person transmission. Hantaan virus spreads via inhalation of aerosolized rodent excreta from its reservoir, Apodemus agrarius (striped field mouse).
Where does Hantaan virus circulate?
Hantaan virus circulates primarily in East Asia. Its main reservoir is Apodemus agrarius (striped field mouse).
