Resolution criteria

This market resolves to "YES" if the World Health Organization (WHO) formally designates the current hantavirus outbreak as a Public Health Emergency of International Concern (PHEIC) at any point on or before December 31, 2026. Otherwise, it resolves to "NO".

Resolution will be based on official announcements published on the World Health Organization website (https://www.who.int/). If the WHO releases a statement or official notification confirming the classification of the outbreak as a PHEIC, the market will resolve to "YES".

Background

A Public Health Emergency of International Concern (PHEIC) is the highest level of alert issued by the WHO under the International Health Regulations. It is defined as "an extraordinary event which is determined, as provided in these Regulations: to constitute a public health risk to other States through the international spread of disease and to potentially require a coordinated international response."

Hantaviruses are a family of viruses spread mainly by rodents and can cause varied disease syndromes in people worldwide, such as Hantavirus Pulmonary Syndrome (HPS) and Hemorrhagic Fever with Renal Syndrome (HFRS). While localized outbreaks occur, the WHO has not historically classified hantavirus outbreaks as PHEICs.
