The contained Andes virus outbreak aboard the MV Hondius in spring 2026, which produced just 13 cases and three deaths before WHO declared it over in July with no secondary transmission after May 25, underpins the 98% market-implied probability against a hantavirus pandemic this year. Most hantaviruses are strictly zoonotic, spreading via aerosolized rodent urine, feces, or saliva rather than sustained human-to-human contact; only the Andes strain shows limited person-to-person transmission, and that requires prolonged close exposure. Official CDC and WHO surveillance confirms no community spread or mutations enabling broader respiratory transmission, consistent with historical patterns of localized outbreaks. While a novel rodent-driven surge or genetic shift could theoretically alter dynamics, current epidemiological data and containment success make such scenarios remote before year-end.
