What happened

WHO publishes Disease Outbreak News (DON) when it wants rapid global awareness of an event. DON numbers (such as 2026-DON600) are unique notice IDs.

Why it matters

Travelers, clinicians, and journalists search DON numbers during crises. Linking DON text to maps and email alerts reduces missed updates.

Symptoms to watch

DON pages list clinical features only when WHO includes them - there is no standard symptom block for every disease.

Who may be affected

Populations named in the DON - sometimes travelers on a specific itinerary, sometimes residents of a region.

What officials say

WHO is the authoritative voice in the DON; national agencies may publish complementary HANs or press releases (for example CDC HAN 00528 for hantavirus).
