How it spreads
Transmission routes differ by pathogen; follow WHO, CDC, ECDC, or national guidance for accurate, pathogen-specific information.

Why people track it
Yellow fever often appears in official dashboards when activity rises, investigations open, or travel rules change. OutbreakThreat does not estimate personal risk; we surface what agencies have already published so you can read the original notice in context.
