**Trader consensus at 98% against a hantavirus pandemic in 2026 reflects the virus’s established transmission patterns and the rapid containment of the only notable 2026 event.** Most hantaviruses, including those causing hantavirus pulmonary syndrome, spread primarily through inhalation of aerosolized rodent urine, droppings, or saliva rather than sustained human-to-human contact; the Andes virus strain is the sole exception with documented limited person-to-person transmission via close respiratory exposure. The MV Hondius outbreak, which began with a likely rodent exposure in South America and produced 13 confirmed or probable cases and three deaths through April–May 2026, was contained through quarantine, contact tracing across dozens of countries, and monitoring that ended without secondary community spread by early July. Official assessments from the WHO and CDC continue to classify global risk as low, consistent with historical annual incidence of roughly 10,000–100,000 cases worldwide that remain focal and rodent-driven. A realistic shift would require either undetected mutations enabling efficient airborne or presymptomatic spread or a new large-scale zoonotic spillover in a densely populated area before enhanced surveillance detects it—scenarios not supported by current genomic or epidemiological data.
