Otherwise, this market will resolve to "No".

An explicit characterization includes official WHO statements, reports, press briefings, or publications that clearly describe the outbreak as a "pandemic." A Public Health Emergency of International Concern (PHEIC) alone will not qualify unless it is also described as a pandemic.

The primary resolution source for this market will be official WHO communications. A consensus of credible reporting may also be used.

Masernfälle in den USA im Jahr 2026?

This market resolves based on the total number of West Nile neuroinvasive disease cases (encephalitis, meningitis, and acute flaccid paralysis) reported among New York City residents in 2026, as published by the New York City Department of Health and Mental Hygiene on its West Nile Virus Reports page at nyc.gov/site/doh/health/health-topics/west-nile-virus-reports.page.

Cases are counted as whole numbers, so each outcome covers a distinct range with no overlap or gap.

The 2026 count shown on the source as of January 1, 2027 is the starting figure. 

If the DOHMH publishes or revises the 2026 count on or after January 1, 2027, this market will resolve based on the count shown on the source at 11:59 PM ET on the 14th day after the first such update, or on March 31, 2027, 11:59 PM ET, whichever comes first. If no such update occurs, this market will resolve on March 31, 2027, 11:59 PM ET, based on the 2026 count shown on the source at that time.

If no 2026 count has been published on the source by March 31, 2027, 11:59 PM ET, this market will resolve based on the sum of 2026 West Nile neuroinvasive disease case counts reported by CDC ArboNET for the five New York City counties (Bronx, Kings, New York, Queens, and Richmond). Revisions published after this market resolves will not be considered. If the DOHMH changes its reporting format or URL structure, the closest equivalent NYC Health Department publication of 2026 West Nile neuroinvasive case data will be used.

Screwworm National Emergency declared by...?

This market will resolve to "Yes" if, at any point between market creation and September 30, 2026, 11:59 PM ET., a confirmed case of Ebola is reported in a country that had not reported any confirmed Ebola case in the current outbreak as of market creation. Otherwise, this market will resolve to "No".

The "current outbreak" is the Bundibugyo ebolavirus outbreak declared by the DRC on May 15, 2026. A "qualifying country" is any country other than the Democratic Republic of the Congo, Uganda, or France, each of which had recorded at least one confirmed case attributable to this outbreak as reported by Centers for Disease Control and Prevention (CDC) https://www.cdc.gov/ebola/situation-summary/index.html.

A "confirmed case" is a laboratory-confirmed Bundibugyo ebolavirus infection attributed to the current outbreak. A case counts for whichever country the qualifying source assigns it to in its reporting, regardless of where exposure, symptom onset, or specimen collection occurred. Resolution turns on the date a qualifying source publishes the confirmation — not the date of exposure, onset, or laboratory result. A report published after the deadline does not count even if the infection occurred earlier.

The primary resolution sources for this market will be official information from the relevant national and international health authorities, including CDC and the World Health Organization (WHO); however, an overwhelming consensus of credible reporting will also suffice.

The resolution source for this market will be official information from the CDC.

Neue besorgniserregende COVID-Variante vor 2027?

This market will resolve according to the weekly influenza-associated hospitalization rate per 100,000 population for the United States, as reported by CDC FluSurv-NET for the specified week.

The resolution source for this market will be CDC FluView / FluSurv-NET (see: https://www.cdc.gov/fluview/index.html). If the FluSurv-NET hospitalization rate for the specified week is not released by 11:59 PM ET on the tenth calendar day following the date of the prior FluView weekly report release, this market will resolve to the lowest bracket.

CDC FluView reports the weekly FluSurv-NET hospitalization rate per 100,000 population to one decimal point (e.g., 0.1). Thus, this is the level of precision that will be used when resolving the market. 

Note: Only the CDC FluSurv-NET weekly hospitalization rate per 100,000 population for the specified week will qualify, regardless of the cumulative influenza-associated hospitalization rate, estimates, projections, state-level reports, or other influenza surveillance metrics published by the CDC or other sources.
