Hantavirus in China.
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. Hantaan virus is the dominant strain in agricultural regions; Seoul virus is more common in port cities. China has used a bivalent inactivated Hantaan/Seoul vaccine since the 1990s, with strong coverage in the highest-incidence rural counties. The Yunnan Province cluster currently logging an annual seasonal peak is consistent with the multi-year pattern of late-spring upticks driven by spring rainfall and rodent migration into rice fields.
