About This Event
This market will resolve to "Yes" if the CDC issues a Level 3 (“Reconsider Nonessential Travel”) Travel Health Notice for any disease by December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". A Level 3 notice listed for any amount of time during this market’s timeframe will suffice for a "Yes" resolution. The primary resolution source for this market will be the CDC’s official Travel Health Notices page (https://wwwnc.cdc.gov/travel/notices); however, a consensus of cred
Current Market Outlook
The market is pricing a 60% chance the CDC issues a Level 3 Travel Health Notice before 2027. That is not a sure thing, but it is the market's base case. It means the crowd sees an active outbreak or new disease threat as more likely than not within the next 170 days. For context, the CDC currently has zero Level 3 notices active. The last one was for the Mpox outbreak, which was downgraded in May 2023.
Key Factors Driving the Odds
The biggest factor is the ongoing H5N1 bird flu situation in the United States. As of April 2026, the CDC has confirmed 68 human cases since 2024, mostly among dairy and poultry workers. The virus has not achieved sustained human-to-human transmission, which is the threshold for a Level 3 notice. But the market is pricing in a 60% chance that changes by year-end.
Second, the 2026 dengue fever season is underway in the Americas. Brazil reported 2.1 million cases in the first quarter alone. If dengue spills into Puerto Rico or the U.S. Virgin Islands at high enough rates, the CDC could issue a Level 3 for those territories. That happened in 2024 for Puerto Rico.
Third, the market is betting on a new pathogen. The World Health Organization's 2025 priority pathogens list includes "Disease X" and several novel coronaviruses. A 60% probability suggests traders believe a new Level 3-worthy event is more likely than a quiet year.
What Could Change These Odds
The biggest risk is H5N1 mutating for human transmission. The USDA reported in March 2026 that the virus is now circulating in 48 states. A single mutation in the hemagglutinin protein could trigger widespread human cases. That would push the probability toward 90% or higher.
On the downside, if the summer and fall pass without a new outbreak, the odds will collapse. The CDC typically downgrades Level 3 notices within 3-6 months of an outbreak peaking. If we hit November with no new notices, the market should trade below 20%.
The key dates are the summer travel season (June-August), when disease surveillance is highest, and the CDC's October 2026 advisory committee meeting, which could change travel notice criteria.

Overview
This prediction market asks whether the U.S. Centers for Disease Control and Prevention (CDC) will issue a Level 3 Travel Health Notice ("Reconsider Nonessential Travel") for any disease by December 31, 2026. Level 3 is the second-highest tier in the CDC's four-level travel notice system, which ranges from Level 1 ("Practice Usual Precautions") to Level 4 ("Avoid All Travel"). The CDC issues these notices based on the risk of disease transmission in specific destinations, often triggered by outbreaks of infectious diseases such as COVID-19 variants, mpox, dengue, or yellow fever. A Level 3 notice indicates a high risk to travelers and recommends they avoid nonessential trips to affected areas. The CDC's Travel Health Notices page (wwwnc.cdc.gov/travel/notices) is the primary resolution source. The market will resolve to "Yes" if any Level 3 notice is active for any amount of time during the market's timeframe, regardless of the disease or destination. This includes new notices issued after the market's start or existing notices that remain in effect. The market does not require a specific disease or region; any Level 3 notice qualifies. Recent history shows the CDC has issued Level 3 notices for a variety of diseases. During the COVID-19 pandemic, the CDC issued Level 3 and Level 4 notices for nearly every country. In 2022, the CDC issued a Level 3 notice for mpox (then called monkeypox) after the global outbreak. In 2023 and 2024, the CDC issued Level 3 notices for dengue in several countries, including Brazil and Thailand, and for polio in a few nations. The frequency of these notices depends on global disease surveillance and outbreak severity. People are interested in this market because it touches on public health preparedness, travel industry impacts, and the likelihood of future pandemics or major outbreaks. Travelers, airlines, and tourism boards monitor these notices closely, as they can influence travel decisions and economic activity. The market also reflects broader concerns about emerging infectious diseases and the effectiveness of global health surveillance systems.
Historical Context
The CDC's Travel Health Notice system was established in 2013, replacing a simpler two-tier system. The current four-level system was introduced in 2017. Level 3 notices have been issued for a range of diseases including COVID-19 (2020-2022), Ebola (2014-2016, 2018-2020), Zika (2016-2017), yellow fever (outbreaks in Brazil and Angola), and polio (2022-2023). The most frequent Level 3 notices in recent years have been for dengue, with multiple countries affected annually. During the COVID-19 pandemic, the CDC issued Level 3 notices for nearly every country at various points. In March 2020, the CDC issued a Level 3 notice for global travel, effectively advising against all nonessential international travel. This was unprecedented in scope. The system was strained as the CDC tried to keep up with rapidly changing risk levels. By 2021, the CDC added a Level 4 category specifically for COVID-19 hotspots, which later became more common. Since 2022, the CDC has issued Level 3 notices for mpox (August 2022), polio (September 2022), and dengue (multiple countries in 2023 and 2024). The mpox notice was notable because it marked the first time a Level 3 notice was issued for a disease that was not primarily travel-associated. The polio notice was issued after cases were detected in New York and London, showing that domestic cases can trigger travel advisories. The dengue notices have become routine, with the CDC updating its list each year based on seasonal transmission patterns.
Why It Matters
A Level 3 notice from the CDC has real economic consequences. The travel and tourism industry, which contributed $1.9 trillion to the U.S. economy in 2023 according to the U.S. Travel Association, can be significantly affected. When the CDC issued a Level 3 notice for Mexico in 2020 due to COVID-19, U.S. airline bookings to Mexico dropped by over 60% in a single month. Even a single Level 3 notice for a popular destination can shift travel patterns and reduce consumer spending. Beyond economics, these notices affect public health decisions. Travelers who ignore Level 3 warnings may face higher insurance costs, difficulty getting medical care abroad, or quarantine upon return. The notices also signal to healthcare providers to consider specific diseases when diagnosing returning travelers. For example, a Level 3 notice for dengue in Southeast Asia prompts doctors to test for dengue in patients with fever who recently visited Thailand or Vietnam. The market's outcome will reflect the state of global disease surveillance and the likelihood of future outbreaks that could disrupt travel.
Current Status
As of late 2024, the CDC has active Level 3 notices for dengue in several countries including Brazil, Thailand, India, and the Philippines. There is also a Level 3 notice for polio in Afghanistan and Pakistan. No new major outbreaks have triggered additional Level 3 notices in recent months. The WHO has not declared any new PHEICs since the end of the COVID-19 PHEIC in May 2023. Looking ahead to 2026, the main candidates for new Level 3 notices include a potential resurgence of mpox (especially the more severe clade I), a new influenza pandemic (such as H5N1 bird flu), or a major dengue outbreak in a new region like Europe or the United States. Climate change is expanding the range of mosquito-borne diseases, which could lead to more Level 3 notices for areas not previously affected. The CDC has also been updating its risk assessment methodology, which could make it easier or harder to issue Level 3 notices in the future.
Frequently Asked Questions
What does a CDC Level 3 travel notice mean?
A Level 3 notice means the CDC recommends travelers reconsider nonessential travel to the affected destination due to a high risk of contracting a serious disease. It is the second-highest warning level, below Level 4 which advises avoiding all travel.
How often does the CDC issue Level 3 notices?
In a typical year, the CDC issues 10-20 Level 3 notices. This number spiked dramatically during the COVID-19 pandemic in 2020-2021. Since 2022, the number has returned to near-normal levels, with most notices for dengue and polio.
