**Trader consensus at 98.9% against a hantavirus outbreak by June 30 reflects the contained nature of the only recent cluster—the Andes virus cases linked to the MV Hondius cruise ship in April–May 2026.** That event produced roughly 12–13 confirmed or probable cases and three deaths among passengers and crew, with person-to-person transmission limited to close contacts; no community spread occurred. As of mid-June, CDC and WHO monitoring of exposed individuals across multiple countries, including 41+ people in the United States, has detected no additional cases. The 42-day observation windows for most contacts are nearing completion without new symptomatic infections, consistent with the virus’s typical 1–8 week incubation period and the absence of ongoing rodent exposure or secondary chains. Sporadic Sin Nombre virus cases continue at historical U.S. baseline rates (fewer than 50 annually), but these do not meet outbreak thresholds. The primary uncertainty remains whether an undetected secondary transmission or unrelated rodent-driven cluster could emerge in the final two weeks; however, current surveillance data and the short remaining timeframe make this scenario improbable.
