Where to Find Travel Warnings Related to Health Risks Abroad

The question of where to find travel warnings specifically related to health risks is one that catches many travellers off guard, because health risk information is distributed across a different set of portals than security and political warnings. Most people know to check the FCDO for terrorism risks or civil unrest. Far fewer know where to go when they want to understand whether their destination is currently experiencing a disease outbreak, what vaccinations are required or recommended, whether the water is safe, or whether a novel pathogen has been reported in the region in the past weeks.

The answer involves a layered system of government and intergovernmental sources, each operating at a different level of detail and update frequency. Getting the full picture requires knowing which source to consult for which type of health risk information — and understanding how those sources connect to each other. Travel Warning Check provides a cross-government health risk score for over 55 destinations as part of its full report, pulling from the same government advisory systems described below into a single consolidated risk verdict. But the sources themselves are the foundation, and every traveller should understand what each one covers.

The FCDO Country Health Sections

For UK nationals, the journey begins at gov.uk/foreign-travel-advice. Every country page on the FCDO portal contains a dedicated Health section, positioned alongside the safety, entry requirements, and local laws sections. This is where the FCDO summarises the key health risks relevant to British nationals travelling to that specific country — including information on healthcare quality, what medical facilities exist and what standard to expect, whether particular vaccinations are required for entry, and whether any specific health alerts are active.

Each FCDO country guide includes a health section with advice, and the FCDO links extensively to TravelHealthPro as the experts on health risks overseas. TravelHealthPro’s website has specific advice on the health risks travellers will face in their destination country, as well as recommendations on vaccines and other precautions they can take. The NHS also provides general information on travel vaccinations. GOV.UK

The FCDO Health section is a signposting tool rather than a clinical reference — it points travellers towards the right specialists rather than attempting to replicate their depth of coverage. For the most serious or rapidly evolving health situations, the Warnings and Insurance section at the top of each country page will also contain specific health-related warnings if the FCDO has assessed a health risk as sufficiently serious to affect the overall advisory level.

TravelHealthPro: The UK’s Primary Specialist Health Travel Resource

TravelHealthPro, operated by the National Travel Health Network and Centre (NaTHNaC), is the UK government’s designated specialist reference for travel health — the source the FCDO links to from every country page it publishes. For any British traveller wanting granular health risk information for a specific destination, TravelHealthPro is the primary port of call after the FCDO.

Travellers can visit the Country Information pages of TravelHealthPro’s website to find useful resources and recommendations on travel vaccinations, malaria, disease outbreaks and other risks where relevant. Travelhealthpro

The platform operates on two parallel tracks. Its country information pages provide destination-specific vaccine recommendations, malaria risk assessments, food and water safety guidance, and information on insect-borne disease risks for every country in the world. Its outbreak surveillance database, accessible at travelhealthpro.org.uk/outbreaks, tracks active disease outbreaks worldwide in near real-time, organised by a three-tier alert system.

TravelHealthPro’s alert feature categorises risk levels for disease outbreaks, special events, mass gatherings, and natural disasters worldwide. Green alerts indicate that usual precautions for the destination should be followed. Amber alerts indicate that extra precautions should be followed and the situation should be monitored closely. Red alerts follow FCDO travel advice, meaning FCDO has advised against all or all but essential travel. Travelhealthpro

As of mid-March 2026, the TravelHealthPro outbreak surveillance database carries active alerts including mpox clade Ib cases confirmed in Austria and Sweden, chikungunya outbreaks across multiple countries in South America and the Caribbean, yellow fever alerts in Bolivia and Peru, and a Shigella and Salmonella outbreak in travellers returning from Cape Verde that has been running since October 2025. These are updates that would not necessarily reach a traveller who consulted only the FCDO’s country pages without also checking TravelHealthPro’s live outbreak feed. Travellers are advised to subscribe to FCDO destination advice for security updates and travel warnings, while using TravelHealthPro’s alert feature for health-specific monitoring. Travelhealthpro

The CDC’s Travel Health Notices

For the most comprehensive real-time picture of global disease outbreak activity affecting international travellers, the CDC’s Travel Health Notices portal at wwwnc.cdc.gov/travel/notices is the world’s most systematically maintained public reference of this type. The CDC uses Travel Health Notices to inform travelers about global health risks during outbreaks, special events or gatherings, and natural disasters, and to provide advice about protective actions travelers can take to prevent infection or adverse health outcomes. CDC

Notices are graded across four levels. Level 1 means practice usual precautions. Level 2 means practice enhanced precautions. Level 3 means reconsider non-essential travel due to significant health risk. Level 4 means avoid all travel due to extreme health risk with no available precautions.

The portal is updated continuously — 794 notices were active or had been issued as of mid-March 2026, covering active outbreaks including yellow fever in Venezuela (issued 16 March 2026), chikungunya in Mayotte (10 March 2026), a Global Polio notice updated 9 March 2026 covering more than 25 countries, and global dengue transmission affecting at least 15 countries. The CDC also maintains destination-specific pages at wwwnc.cdc.gov/travel/destinations/list, which bring together all active Travel Health Notices alongside vaccine recommendations and destination-specific health risk information for every country in the world.

UK travellers planning trips to the United States, Canada, or other destinations where the CDC is the primary health authority for outbreak intelligence will find the CDC portal provides information that TravelHealthPro may not cover in the same level of detail. Cross-referencing both for any destination is a sound practice.

The WHO Disease Outbreak News and Travel Advice Portal

The World Health Organization publishes two complementary resources that together represent the global institutional authority on disease outbreak intelligence relevant to travellers.

WHO’s Disease Outbreak News are published relating to confirmed or potential public health events of unknown cause with significant international health concern that may affect international travel or trade, or known causes which have demonstrated the ability to cause serious public health impact and spread internationally. WHO These reports are available at who.int/emergencies/disease-outbreak-news and represent the WHO’s formal communication of outbreak events under the International Health Regulations — the framework that governs global health emergency notification between member states.

The WHO’s dedicated travel advice portal at who.int/travel-advice consolidates the organisation’s guidance for international travellers, including its yellow fever country list, dengue and chikungunya advisories, and updates for travellers in response to specific outbreak events. This is the authoritative international reference for understanding which countries have active requirements or recommendations around specific vaccines, and which regions the WHO has identified as currently posing elevated risk for particular diseases.

The WHO’s International Health Regulations Emergency Committee confirmed on 1 March 2026 that the poliovirus situation continues to constitute a public health emergency of international concern with respect to wild poliovirus type 1 and circulating vaccine-derived polioviruses WHO — meaning that poliovirus retains its formal PHEIC designation and that the polio precaution applies to travellers heading to any of the more than 25 countries currently listed as affected.

Canada’s Public Health Agency Travel Health Notices

Canadian nationals and, usefully, any traveller seeking a second government’s assessment of health risks should consult the Public Health Agency of Canada’s travel health notices at travel.gc.ca/travelling/health-safety/travel-health-notices.

The Public Health Agency of Canada’s travel health notices outline potential health risks to Canadian travellers and recommend ways to help reduce them. A level 3 travel health notice warns travellers to avoid non-essential travel to the destination due to high risk to the traveller’s health. A level 4 travel health notice advises travellers not to travel to the destination for any reason. Travel.gc.ca

Canada’s health travel notice system operates parallel to — but independently from — the CDC’s system. Comparing the two can reveal cases where one government’s health intelligence network has identified an evolving risk before the other has formally issued a notice, providing an earlier signal to travellers planning trips to affected destinations.

The broader Canadian government travel health portal at travel.gc.ca/travelling/health-safety provides health risk information, vaccination guidance, and destination-specific health advice for Canadians — and is freely accessible to any traveller regardless of nationality.

Australia’s Smartraveller Health Resources

The Australian government’s Smartraveller platform integrates health risk information directly into its country advisory pages, making it one of the more seamlessly integrated national travel health warning systems available. Each destination page on Smartraveller carries a Health section covering vaccination requirements, healthcare quality, the availability of specific medications, and whether any active health alerts apply.

The Australian government’s advice to travellers heading to destinations with active health risks includes keeping up to date about health risks with Smartraveller subscriber alerts, protecting against insect-borne diseases and diseases spread by animals, practising good personal hygiene and food safety, and avoiding contaminated food and water. Smartraveller

The Smartraveller subscription service allows travellers to receive email notifications when health-related advisories are updated for any destination they have registered. The Australian Department of Health recommends that travellers research their destinations on the Smartraveller website, see a doctor for medical advice and to find out what vaccinations they need for travel, and visit the Smartraveller website regularly to check for international developments and subscribe to updates. Australian Government Department of Health

The FCDO Country Health Pages in Practice

Each FCDO country page structures its health information consistently, which helps travellers know where to look regardless of destination. The standard sections within the FCDO’s Health tab cover healthcare availability and quality in that country, recommended vaccines and whether any are required for entry, malaria risk and prophylaxis recommendations where relevant, the availability of prescription medications, and links through to TravelHealthPro for the full clinical detail.

For a country currently experiencing an active outbreak that the FCDO has assessed as affecting British nationals significantly, health information will also appear in the Warnings and Insurance section at the top of the page — the most prominently displayed part of any FCDO country advisory. This cross-placement between health and warnings sections reflects the FCDO’s acknowledgement that health risks, when severe enough, function as travel warnings in the same operational sense as security risks.

Country-specific information on medical facilities can be found in the health section of the FCDO foreign travel advice pages, alongside links to TravelHealthPro which explains best practice when travelling with medicines, and NHS guidance on whether specific medicines can be taken abroad. GOV.UK

Building a Health Warning Check Into Pre-Booking Research

The architecture of travel health warning information rewards a systematic approach. No single source covers everything. The most current picture comes from layering the FCDO country health section (for UK-specific advice and healthcare quality information), TravelHealthPro outbreak surveillance (for live outbreak alerts tiered by severity), the CDC Travel Health Notices (for the most comprehensive global outbreak database), and the WHO’s Disease Outbreak News (for formal international health emergency reporting). Travel Warning Check draws on government data from four countries simultaneously — including the health and medical risk category — making it the most efficient starting point for a rapid pre-booking health risk assessment before conducting the deeper source-by-source checks.

The timing of this research matters as much as the sources used. It is recommended to check the travel health notice page for your destination twice: once when planning the trip, and again shortly before departure. Health, safety and security conditions may change between the date you book your travel and your departure date. Travel.gc.ca A destination carrying no active health alerts at the time of booking may have acquired one by the time of departure — particularly for mosquito-borne diseases, which are seasonal and can move rapidly between regions.

The subscription services offered by TravelHealthPro and Smartraveller mean that travellers do not need to actively revisit these portals to stay informed. Both allow travellers to receive email notifications when health-related information is updated for any subscribed destination, providing a passive monitoring layer that supplements the active checks conducted at booking and departure.

Quick Takeaways

• The FCDO country Health section at gov.uk/foreign-travel-advice is the starting point for UK nationals, providing healthcare quality information, vaccine requirements, and links through to TravelHealthPro for full clinical detail.
• TravelHealthPro at travelhealthpro.org.uk is the UK government’s specialist health travel resource, operating both destination-specific country information pages and a live outbreak surveillance database tiered by green, amber, and red alert categories.
• The CDC Travel Health Notices at wwwnc.cdc.gov/travel/notices maintain the world’s most comprehensive continuously updated database of active disease outbreaks affecting travellers, with formal notice levels from 1 through 4.
• The WHO’s Disease Outbreak News and travel advice portal represent the formal international health emergency reporting framework, including the current poliovirus PHEIC designation and ongoing mpox and dengue advisories.
• Canada’s travel health notices and Australia’s Smartraveller health pages provide additional independent government health warning sources worth cross-referencing, particularly for destinations where health risk intelligence is evolving rapidly.
• Check health warnings twice: at the point of booking and again in the 48 hours before departure, as outbreak situations can change materially between those two moments.
• Travel Warning Check consolidates government data across four countries including the health and medical risk category into a single real-time safety score, making it the fastest cross-government starting point before moving to source-specific research.

Frequently Asked Questions

Where do UK travellers find official health warnings for overseas destinations?

The primary official source for UK nationals is the Health section of each country page at gov.uk/foreign-travel-advice, which is directly linked to TravelHealthPro — the UK government’s specialist travel health resource operated by NaTHNaC. Each FCDO country guide includes a health section with advice, and the FCDO links extensively to TravelHealthPro as the experts on health risks overseas, with TravelHealthPro providing specific advice on the health risks travellers will face in their destination country as well as recommendations on vaccines and other precautions. GOV.UK

What is the difference between the FCDO health section and TravelHealthPro?

The FCDO Health section is a summary signposting tool that covers healthcare quality, key vaccine requirements, and general health risks at a country level, directing travellers to TravelHealthPro for full clinical detail. TravelHealthPro provides the complete vaccination recommendations, malaria risk zones, disease-by-disease risk assessments, and operates a live outbreak surveillance database with a three-tier alert system. TravelHealthPro’s alerts categorise risk levels for disease outbreaks, special events, mass gatherings, and natural disasters worldwide, with green indicating usual precautions, amber indicating enhanced precautions, and red following FCDO travel advice against all or essential-only travel. Travelhealthpro

Does the WHO publish travel health warnings that travellers can access directly?

Yes. The WHO’s Disease Outbreak News are published relating to confirmed or potential public health events of unknown cause with significant international health concern that may affect international travel or trade, or known causes which have demonstrated the ability to cause serious public health impact and spread internationally. WHO These are available at who.int/emergencies/disease-outbreak-news. The WHO’s travel advice portal at who.int/travel-advice consolidates travel-specific guidance including its yellow fever country list, dengue and chikungunya advisories, and outbreak-specific traveller guidance.

How often is the CDC Travel Health Notices database updated?

The CDC Travel Health Notices are updated on a continuous basis, with new notices issued whenever the CDC identifies an outbreak or health event meeting its criteria for traveller notification. A Travel Health Notice can be posted for a disease outbreak with higher than expected cases in a country or region, sporadic cases of a disease in an unusual or new geographic location, natural and human-made disasters with severe environmental health risks, and mass gathering events that can lead to disease outbreaks. CDC As of March 2026, the CDC issued new notices as recently as 16 March — the yellow fever warning for Venezuela — demonstrating that the database can and does receive same-week updates during active outbreak events.

Should I check health warnings both when I book and before I travel?

Yes, and specifically twice — once at the time of booking and again in the days immediately before departure. It is recommended to check the travel health notice page for your destination twice: once when planning the trip, and again shortly before departure, because health, safety and security conditions may change between the date you book your travel and your departure date. Travel.gc.ca Subscribing to TravelHealthPro email alerts and FCDO country-specific alerts at the time of booking creates a passive monitoring layer that will notify you of significant changes between those two check points without requiring repeated manual visits to each portal.
