This market will resolve to "Yes" if there is a confirmed case of Hantavirus in the territory of the United States of America reported between market creation and May 15, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". Any laboratory-confirmed hantavirus infection identified within U.S. territory will qualify, regardless of where exposure or symptom onset occurred. The primary resolution source for this market will be official government information (e.g., the CDC); however, an overwhelming consensus of credible reporting will also suffice.Recent confirmation of a laboratory-verified Sin Nombre virus infection, the predominant hantavirus strain causing pulmonary syndrome in the western United States, in a Chelan County, Washington resident has driven the near-certain market consensus. This case, reported by the Chelan-Douglas Health District on or before the May 15 resolution date, aligns with established epidemiological patterns: the CDC records roughly 20–40 such U.S. cases annually, primarily linked to rodent exposure in rural western states. The unrelated Andes virus cluster aboard the MV Hondius cruise ship has produced no domestic confirmations as of May 14, reinforcing that the Washington diagnosis alone satisfies the market criteria. Ongoing surveillance through state health departments and the CDC continues to monitor exposures without altering this outcome.
