This prediction market addresses whether the World Health Organization will declare a new coronavirus pandemic distinct from COVID-19 before the end of 2026. A pandemic declaration by the WHO is a formal recognition that a new infectious disease has spread across multiple countries or continents, affecting a significant number of people. The resolution depends on an official WHO announcement specifically identifying a novel coronavirus, not a variant of SARS-CoV-2, as the cause of a new pandemic. This topic sits at the intersection of virology, global public health policy, and pandemic preparedness, reflecting ongoing scientific concern about zoonotic spillover events and viral evolution. Interest stems from the profound global impact of the COVID-19 pandemic, which began in 2019, and the recognition that coronaviruses represent a significant pandemic threat. Recent scientific reports, including from the WHO's own advisory bodies, continue to highlight coronaviruses as priority pathogens for research and surveillance. The market allows participants to weigh evidence from viral surveillance, genomic sequencing, and epidemiological reports against the historical frequency of novel coronavirus emergence.

Historical Context

The history of coronavirus outbreaks provides critical context for assessing the likelihood of a new pandemic. Before 2002, coronaviruses were primarily known to cause mild common colds in humans. This changed with the 2002-2004 SARS-CoV-1 outbreak, which originated in China and spread to 29 countries, causing over 8,000 cases and 774 deaths with a case fatality rate near 10%. The Middle East Respiratory Syndrome (MERS) coronavirus emerged in Saudi Arabia in 2012 and continues to cause sporadic zoonotic outbreaks, with a case fatality rate of approximately 35%. The most significant event was the emergence of SARS-CoV-2, the virus causing COVID-19. The WHO declared COVID-19 a PHEIC on January 30, 2020, and began describing it as a pandemic in March 2020. This pandemic has resulted in over 700 million confirmed cases and nearly 7 million reported deaths globally as of late 2024. These three major outbreaks in less than two decades demonstrate the coronavirus family's pandemic potential. Scientific consensus indicates that the diversity of coronaviruses in animal reservoirs, particularly bats, and increasing human-animal interface create ongoing spillover risk. The interval between the emergence of SARS-CoV-1 and SARS-CoV-2 was about 17 years.
