This market will resolve to “Yes” if the World Health Organization (WHO) officially declares the hantavirus (or any strain or outbreak of the hantavirus) a Public Health Emergency of International Concern by June 30, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No”. Only a determination that the hantavirus is a Public Health Emergency of International Concern will qualify. Other designations will not be considered. The primary resolution source for this market will be official information from the WHO; however, a consensus of credible reporting may also be used.
