Hantavirus lab leak confirmed by June 30?

This market will resolve to “Yes” if any hantavirus case linked to the hantavirus outbreak on the MV Hondius cruise ship is confirmed to have originated from a medical laboratory or research facility by June 30, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No.” Confirmation that the hantavirus case originated from a medical laboratory, research facility, diagnostic facility, or other controlled laboratory setting is required. Definitive confirmation that the lab-originated case directly caused the outbreak on the MV Hondius is not required, provided a consensus of credible reporting indicates that the lab-originated case is a possible source of, or is otherwise plausibly connected to, the MV Hondius outbreak. Investigations, speculation, statements that a lab origin is possible or has not been ruled out, or statements unverified by a consensus of credible reporting will not suffice. The primary resolution source for this market will be a consensus of credible reporting.
