TL;DR
- WHO Disease Outbreak News is the global reference for confirmed outbreaks.
- CDC Travel Health Notices and ECDC translate outbreak data into traveler guidance.
- ProMED-mail is the fastest informal signal — often days ahead of official confirmation.
- Vaccination requirements (yellow fever, polio) are published by WHO and enforced at borders.
- TravelAlert monitors all four and pushes outbreak news for your specific destinations.

Why outbreak monitoring is hard for travelers
- WHO confirmation can lag the first cases by weeks. CDC posts follow WHO. By the time it's official, you've already been there.
- Outbreak data is fragmented by country, by disease, by agency.
- Vaccination requirements (yellow fever, polio) are enforced at borders — but not all countries publish current rules in English.
- Endemic-vs-outbreak language is confusing. 'Dengue present in Thailand' is true year-round; you care about whether cases are above baseline this month.

Frequently asked questions
What is the best source for global disease outbreak news?
WHO Disease Outbreak News is the authoritative confirmed-outbreak source. ProMED-mail is the fastest informal signal — often days or weeks earlier. TravelAlert monitors both.
How early do outbreak warnings reach travelers?
Informal networks like ProMED often surface signals weeks before WHO confirmation. Official CDC travel notices typically follow within days of WHO confirmation. TravelAlert pushes both as they appear.
Are yellow fever vaccinations still required to enter some countries?
Yes — for many countries in sub-Saharan Africa and parts of South America, proof of yellow fever vaccination is required at the border if you've been in an endemic zone. WHO publishes the current list.
Should I worry about dengue?
Dengue is endemic across much of the tropics. The question is whether cases are above baseline in your specific destination this season — exactly what outbreak surveillance tracks.
Does TravelAlert recommend vaccinations?
We surface official requirements and current outbreak context, but vaccination decisions should be made with a travel-medicine clinic.
