Travel Health: Disease Risk by Country
Country-by-country disease history and WHO regional context for travelers. Browse 236 countries grouped by 6 WHO regional offices.
Plan Health-Aware Travel
Before you travel, scan the disease history for your destination. We have 3,149 WHO-tracked outbreak events on file across 236 countries and territories — one verified record per WHO Disease Outbreak News publication.
This page groups countries by WHO regional office. Open any region to find the countries with the most reported events; open a country to see every disease ever reported from there. None of this replaces a clinician’s pre-travel consult — it gives you context for that conversation.

Frequently Asked Questions
Should I cancel a trip if I see an outbreak event?
One outbreak event is rarely a reason to cancel travel. Use the country profile to see the full history and consult your national travel health authority (CDC, NHS, ECDC) for current guidance.
Which diseases matter most for international travelers?
The list to the right shows diseases reported in 8 or more countries — these have the broadest geographic footprint. Cholera, dengue, and viral hemorrhagic fevers commonly appear at the top.
What does the WHO region grouping mean?
The World Health Organization divides the globe into six regional offices (AFR, AMR, EMR, EUR, SEAR, WPR) that coordinate surveillance. Two countries in the same region often share epidemiological context, mosquito vectors, or outbreak response infrastructure.
