Trader consensus on no hantavirus pandemic in 2026 at 97.5% reflects the successful containment of the limited Andes virus cluster aboard the MV Hondius expedition ship earlier this year. Official CDC and WHO data show roughly 12–13 confirmed cases and three deaths from person-to-person spread in close-contact settings, with no sustained community transmission or rodent-linked amplification detected after exhaustive contact tracing of hundreds of individuals across multiple countries. Andes virus remains the only hantavirus with documented human-to-human transmission, yet it requires prolonged proximity and has not produced broader outbreaks historically. U.S. surveillance continues to report only sporadic, rodent-exposure cases with no pandemic indicators. While new zoonotic spillovers or rare mutations could theoretically alter dynamics, current epidemiological patterns and monitoring data support the market-implied outcome.
